I've been learning about web services, and I'd like to try my hand at
some basic Java RPC calls with XML/Soap.  I've seen several approaches,
using Apache Axis, Apache SOAP, or the Java Web Services kit. 

I'm a little unsure which one would be the best (read: simplest) to
learn on.  All I really want to do is experiment with XML RPC calls to
localhost.  I need to figure out if the Java kit from Sun is best, which
wraps RPC calls into JAXRPC, or to stick with the Apache SOAP
implementation, with either SOAP or Axis.  The approaches are quite
different, so I'd rather just learn one or the other right now.

I'm having trouble with the Java config.xml and web.xml setups, and
getting Tomcat to load the servers.

Does anyone have any suggestions?

If you want a started, you could pick up Apache's XML-RPC java package, 
which contants xml-rpc classes and simple webserver classes, so all you 
need to do is plug in your rpc modules in and play.

This is not direct SOAP, but I think it is a nice starter to see how 
things work.

Unless you have a specific desire to learn SOAP (the protocol, not the
Apache project of the same name), you might consider looking at XML-RPC
(the protocol). For all intents and purposes, XML-RPC is the primordial
ooze from which SOAP evolved.

Specification: <http://www.xmlrpc.com/>
Apache Java Implementation: <http://xml.apache.org/xmlrpc/>

IMO, Apache SOAP is probably the easiest to learn (of the three projects
you mention). It doesn't support some of the more recent SOAP 
developments
(e.g., WSDL, UDDI) and has the performance disadvantage of using DOM
instead of SAX in the XML pipeline. However, for learning purposes it's
fairly easy to get some basic services working.

Apache Axis is essentially a re-write of Apache SOAP to support the
latest SOAP protocols and improve performance (and thankfully remove the
name collision between project and protocol).

JAXRPC (along with JAXM) is Sun's attempt at creating generic APIs for
XML-based message-passing (both synchronous and asynchronous). The
distribution consists of interfaces and a reference implementation. It
is an express goal of Axis's to implement the JAXRPC interfaces.

My recommendation: get your feet wet with either Apache XML-RPC or 
Apache
SOAP. Then, if you're still interested start learning JAXRPC. 
Ideally, in
the future it'll be possible to plug-in any SOAP implementation in a
similar manner to XML parsers today (via JAXP).

This problem has me pulling my hair out.  Here's a cut and paste of a
sample run.  I started rmiregistry, then 'comp' which is an alias to run
the correct class.  It threw the exception.  I broke out of rmiregistry,
ran it again, and ran my class again, and it worked.  Any idea why this
might happen?  Could there be a huge delay in the code somewhere where a
port isn't getting bound quickly enough?

local:~/myjava> comp
ComputeEngine exception: RemoteException occurred in server thread;
nested exception is: 
java.rmi.UnmarshalException: error unmarshalling arguments;
nested exception is: 
java.lang.ClassNotFoundException:
engine.ComputeEngine_Stub

Ready.

You're the second person to report this, but I can't reproduce it.  What
version of patch is in your path?  I.e. whats the output of 'patch --version'?

From the trace above, my guess is the rmiregistry needs to have it's
classpath set properly as well. That's why when you ran it in
~/myjava, the code worked (classpath by default includes . in its
environment).

Cheers.

Ok, then I have no idea why the patches apply perfectly for me and not
for you.  I assume what you have downloaded checksums correctly and all
that?  If so, try cvsup'ing and make sure what you have is fine from that
point of view.

Hi:

The Jboss 3 port seems to run fine using "java -jar run.jar".  However, the jboss3ctl script (and thus startup.sh) seems to be broken.  Unfortunately, there isn't any source included (or is there?), so I don't know what it's doing.  It runs (when I do "jboss3ctl start"), and claims to startup jboss, and set the PID.  However, it doesn't run, and when I run "jboss3ctl stop" it explains that jboss was never running in the first place.

Is this just my problem, or have other people had this problem?  I have jdk1.2.2/jdk1.3.1 installed, and it seemed to pick this up when I installed it.  As I said, it runs fine with "java -jar run.jar".  Exactly what is jboss3ctl doing when it tries to run jboss?

Please CC me if you respond.  I haven't suscribed to this mailing list.

-Dan

I think I found the problem.  The jboss3ctl seems to be assuming a jdk of 1.2.2, which I have, but am not using.  If I run the jboss3 with the java from 1.2.2, it fails.  If I run it with the java from 1.3.1, it works.  However, the jboss3ctl uses 1.2.2, and fails.

I'm not sure why jboss is failing on 1.2.2--perhaps it setup some specific options when it noticed I had 1.3.1 which don't work with 1.2.2.  However, the jboss3ctl does not seem to be working with 1.3.1.  I'm going to change the jboss makefile to use java=1.3+ and see if that makes a difference.

Hi Dan,

If the jboss3 port uses JDK 1.2, then only JDK 1.2 was available when you 
installed the port. Run 'make clean deinstall install' to make the port use 
your JDK 1.3. If it can't find it, though, it will fallback to a JDK 1.2.

It should work with JDK 1.2 too. Hmmm... Can you tell me what is in the JBoss 
3 log file?

Ernst

Jonathan, you're a genius.  ;-)
I think you solved my problem.  Thanks!  Now I can move on to XML-RPC.

| Unless you have a specific desire to learn SOAP (the protocol, not the

I took a look at XML-RPC, and you are right, that seems to be just what
I am looking for.  I wanted the simplest way to build a web service, and
it looks like that's what I need to do it.  I also wanted to avoid
running a full-blown Apache server just to make a few RPC calls.

| My recommendation: get your feet wet with either Apache XML-RPC or 
| Apache
| SOAP. Then, if you're still interested start learning JAXRPC. 

After looking at the comparison, I can see there is a rather steep
learning curve to parts of SOAP, and also a lot more than I need for
what I want to do.

Can XML-RPC be made to work via http?  For example, my university web
account has a firewall that keeps my applets from contacting the
servlets I've written.  I'd like to be able to attach a web service (a
very simple arithmetic calculator) to the URL for my web page.

So, if my web page is www.foo.edu/~jcm, I'd like to be able to set up
an XML-RPC web service on www.foo.edu/~jcm/calculator, without needing
to run another full-blown webserver, which I don't think I'm allowed to
do anyway.  Is this feasible?

The rmiregistry should never be run with *any* classpth at all.
It should never load classes locally over the filesystem, It 
gets its classpath from the annotated codebase that is gets from every
Remote object that registers with it.

If the registry is run with a local classpath and you do rmi over 
the network (not everythign on the same box) many things will be broken 
because the JVM ignores the annotated codebase that comes with a given 
Object type if it can be found locally and deserialized. So when a different
machine on the network contacts the registry and gets the serialized stub that
stub will have no codebase and there will be no way for the stub to be 
deserialized, resulting in a ClassNotFoundException.

I'm no expert on xml-rpc, I've only just started playing with it, but from
my experiences, you can specify a port nbr to use, and the server can be ru=
n
as a standalone java application.  U don=B9t need to bind it ot a web server
at all (but you can..)

Well, that is interesting.  What I don't get is all I do is run
'rmiregistry&' with no arguments.  But it seems to matter what directory
I'm in.

 Yeah.  I found out some more information.  The log file says that "libhpi" couldn't be found.
Here's the info I've gathered:
1). I did a clean reinstall of jboss3, which created a new daemonctl.c that had 1.3.1 as the path.

2). There is still something interesting on the execl line: the /usr/local/jdk1.3.1/bin/java is the 1st AND second argument.  Taking this out didn't change anything, though.  Is that standard procedure (to put the command twice)?  I have seen something like that before, but I thought the second argument to execl was the first argument to the procedure being run.

3). The startup script now works fine (020.startup.sh).  In fact, if I do 
      su -m www -c "exec jboss3ctl start"
     It also runs fine.  Additionally, I temporarily created a shell for the www user, and this account can also run the daemon w/o a problem.
4). root can run "java -jar run.jar" fine.
5). root cannot run "jboss3ctl start" successfully.  This puts the error into stderr.log I mentioned above:
    /usr/libexec/ld-elf.so.1: Shared object "libhpi.so" not found (I have the lib in the standard place under jdk1.3.1/jre/lib/i386/green_threads)
6). jboss3ctl is user www, group www with these permissions:

    rwsr-sr--

   Theoretically, this means it should already be running as www if I run it from any other account, right?  So why does it seem to require using "su"?
7). It seems like something is wrong with my ENV, or it wouldn't be complaining about the missing lib.  But the www user has no special ENV settings that I know of.  When is su to www (when I created a shell), it has the same ENV as my root user.
8). I created another user, and put them in the www group.  They cannot run jboss3ctl either.
Hope this all helps.
Thanks,
Dan

If the jboss3 port uses JDK 1.2, then only JDK 1.2 was available when you

It should work with JDK 1.2 too. Hmmm... Can you tell me what is in the JBoss 
3 log file?

tomcat4ctl also fails to run (it's essentially identical to jboss3ctl in design).  I'm guessing
something is wrong with the suid bit on this one too.

Maybe it's something in my configuration that's wrong, but I am clueless.

I almost missed this, does this mean it's not possible to make it run on 
-stable, or just that you don't want to port the fixes right now and 
that you'll leave that to a volunteer?

It only works on -stable at this time, but with KSEs coming around the
corner and all bug fixes to thread suspension committed to -current, it
doesn't really make sense for me to keep developing under -stable.

And right, I'd like to get a volunteer to port -current's libc_r to
-stable. I tried hacking it myself, but decided that it was a waste of
my time and that I should focus on core -current libc_r issues and
getting HotSpot working with it instead.

BTW, for a pre-alpha release, it runs surprisingly stable.

As soon as work calms down a bit (release at the end of the month) this
is likely to occur...

hi,

Tried to get tomcat 4 working with sun's jdk 1.4 today,
but always falls to Signal 11 problem :-(

It was surprise for me because ant and javac
are working just fine.

As I could understand from searching recent archives it's
a problem related to unstability linux's HotSpot.

Could anyone suggest way to replace HotSpot with more stable
VM ?

I am open for expirements and patches and hopefully can test
most of them.

Unfortunatelly I'm stick with jdk and tomcat vesions and have to
get this scheme working in order to replace damn buggy linux
with FreeBSD. Only thing stops me is java crashes :-(

PS: And yes, one more requirement -- -STABLE.

Hello everybody;

	As i mentioned in an earlier post, we where blessed with a visit
from a Sun Java guy (Charles Ditzel) courtesy of our local sun reseller
person. we have lotsa good stuff that we bought from him (the reseller,
not charles ) during the closing part of the glory VC days.

	Given my longstanding rabid interest in promoting FreeBSD, I
talked to him about FreeBSD support. He was aware of it's existence, but
not up on the specifics. I didnt find his lack of specific knowledge to be 
troubling because he didnt have specific knowledge about most of the 
stuff. To use a compsci analogy, he seemed to be a root node :-).

	I thanked him on behalf of the list for the support that sun has 
provided up to now ( good suggestion dave! ). I told him that i was 
running 1.3.1p5 pretty flawlessly on FreeBSD and i explained to him that 
the port didnt have hotspot running yet.

	I explained to him further that FreeBSD was going to have some 
challenges moving to 1.4 because of the disappearance of 'classic' mode in 
1.4 and that we could really use some direct contact with Sun Engineers to 
help with HotSpot.

	He was aware of the fact that M$FT has been working in the BSD 
realm and he was interested in facilitating communication between the GBSD 
community and the Sun Java developers.

	So, I would imagine that if we get our heads together and try and 
figure out exactly what it is that we would want from him we would 
probably meet with some success.

	The key point being that we need to create a request that contains 
specific action items that he can 

  1. understand immediately so that he can work on the *problem*, not on 
     trying to figure out what we want.

  2. solve easily by putting us in contact with the person at sun who can 
     help.

If we meet these goals, then we help ourselves by helping him to do his 
developer outreach job effectively. 

I can imagine that being able to write in his self evaluation form for his
salary review 'I helped the FreeBSD Community complete it's port of jdk
1.4.x, thereby expanding the reach of java to X100,000 new machines' would 
make him feel very happy indeed.


I am happy to write the letter, or i am happy to let ernst or greg or bill 
nate or freebsd-core write it. i dont care. i just want this to help 
because i this is a key strategic issue for freebsd.

i hope we can leverage this opportunity!

Hey,

We are glad users of FreeBSD and the patch of the jdk1.3 source. Since
now the jdk1.4 source have been avialable quiet a while I am interesting
in...

Have anybody started to port the jdk1.4 source to FreeBSD and if so
what is current status?

Regards
Kristian K. Nielsen,

Long live a future for Java on FreeBSD.

Na, lay off the guy. I'm probably more directly connect to the Sun JVM
folks in a luny technical capacity than anybody here on this list and this
is mainly because I'm not shy about asking him questions. I know Calvin
Austin and the rest of the folks responsible for the upcoming J2SE 1.5
release, etc... Greg for licensing, etc...

Which has been pretty much nothing at this time on their end as far as raw
dedicated engineers go, but they have provided the license which is a good
thing. Sun's a wierd place, I have access to high level folks to ask
technical support questions, but their political structure doesn't seem to
recognize the BSDs as significant enough to actively support using
engineering resources.

It could be the case that it's too much for them to handle given the
economic times. I certainly understand that. But the task of porting the
entire JVM itself is pretty much localized to the OS port group in
question and you really can't get around those issues (our pthreads bugs, etc...),
so Sun can be of limited help to us anyways.

It's pretty much our show whether we like it or not.

No need to worry any more. The buzz is starting to spread around that
HotSpot is working under FreeBSD now. ;)

How ? what part of the political and corporate structure is he working with ?
This is critical if you want to liason between both groups. He might be
inappropriate to pressure about these things in the same way that I don't
pressure Calvin's group.

We need engineers (roughly 1-2) at Sun to focus on the next release for FreeBSD
and interface with the BSD community about issues related to it. It's got to be
professional much like the Blackdown community. Also, joining the blackdown folks
isn't a bad idea either.

"News"

In that regard, I'm trying to transition out of JVM development and move
into more traditional FreeBSD kernel side stuff, so we need a person
that's capable of doing the work I've done and maintaining it across JVM
revisions. 

I've already begun the process of leaving it to other folks in our group
and refocusing my development effort to KSEs and SMPng.

We've already got that. Tell him what I just told you about our (greg, nate, me)
contact with them already.

It's better for the core engineering folks to deal with the Sun folk directly
or else it might create some confusion just from having too many people poke
into the the mix.

The FreeBSD community is pretty inexperienced with interfacing with corporations
overall and it's best to let folks that understand the politics behind it deal
with the interpersonal and managerial tasks instead. Barraging a random Sun person
about these issues isn't really something productive, which possibly might lead
to a cascade of rumors within Sun making our job more difficult.

It's best to back off unless you know what you're doing. Certainly chatting with
him about what's been going on recently is a good thing.

Problem:

The problem lies in the .java_wrapper script.  This script sets up a few important variables in
the environment that are needed to run the java binary, and then procedes to execute it.  This
works fine most of the time.

See "man sh":

 -p privileged
         Turn on privileged mode.  This mode is enabled on startup if
         either the effective user or group id is not equal to the real
         user or group id.  Turning this mode off sets the effective user
         and group ids to the real user and group ids.  When this mode is
         enabled for interactive shells, the file /etc/suid_profile is
         sourced instead of ~/.profile after /etc/profile is sourced, and
         the contents of the ENV variable are ignored.

According to this, the environment will be ignored if the effective user is not the real user. 
Since this is precisely what will happen if .java_wrapper is invoked by jboss3ctl, it stands to
reason that the necessary vars that are setup in .java_wrapper will be ignored, giving the shared
library error that I get frequently:

 /usr/libexec/ld-elf.so.1: Shared object "libhpi.so" not found

One of the vars that gets set is LD_LIBRARY_PATH.  Note the following from "man ldconfig":

Security
     Special care must be taken when loading shared libraries into the address
     space of set-user-Id programs.  Whenever such a program is run, the
     dynamic linker will only load shared libraries from the hints file.  In
     particular, the LD_LIBRARY_PATH is not used to search for libraries.
     Thus, the role of ldconfig is dual.  In addition to building a set of
     hints for quick lookup, it also serves to specify the trusted collection
     of directories from which shared objects can be safely loaded.

According to this, this var will be ignored in this case, because jboss3ctl is surely a
"set-user-Id" program.  So, the .java_wrapper will fail if called by a suid program like
jboss3ctl.  You could get around this by adding these java libs to the safe paths, but this is
probably not worth it.

Conclusion:

.java_wrapper (apparently sun's current solution) will not work when invoked by a suid program. 
So far, I have encountered two such programs: tomcat, and jboss (essentially the same design).

There is a good reason for not letting suid programs call shared libraries depending on the ENV
variables, so I understand why this happens.

This explains why the bootup script for jboss and tomcat is forced to call su -m www -c
"jboss3ctl" to get the env to work: this avoids a change to user when the executable runs.  If
this worked normally, there would be no reason to force a change with su, because the executable
should already do that.

Solution:

I'm not sure of a good one, because the idea is to allow multiple users to be able to
start/stop/restart the server just by being a member of the group www.  That said, there are many
ways to get minimal functionality:

1). Run as root, using su, like the startup script
2). Use java -jar run.jar
3). Create an account to run the daemon, and allow logins to that account.  Give permissions to
only that account to run it.
4). Fix java so it doesn't need a library path (static).

Please suggest further solutions if you have any ideas.

Errors:

I may have misinterpreted what I found, and my problem may be singular.  I would love to find out
that I am wrong, so if I am, please correct me and explain how to fix my problem.

-Dan

I seem to recall reading that this will only work with 5.x, and
that there were no plans for making it work 4.x.  Is this (still?)
correct?

Is this going to be available in the next patchset?  If so, do you
have any idea when the next patchset will be available?

Thanks.

No, that's kind of up to me at this time. It only runs on -stable, but
only with my hackish bug fix. I'm moving to -current for all of my
new development and that libc_r should be backported to -stable for
more traditional useage.

That's Greg's domain.

Keep in mind, it's pre-alpha and is good for pretty pictures and
playing around at this time.

I thought I answered this one earlier :).  I'm snowed under until the
end of the month (at work) with two product releases.  I expect the next
patchset sometime around July 4th-7th (which is when I'll have time to

I'm having a problem with a java web application that
needs to connect to an oracle db. I just transfered
the application to a FreeBSD box running:
4.6 Release 
linux-jdk-1.3.1.03
jakarta-tomcat-3.3.1_14 
apache-1.3.26

I get the error stated in the subject: 
SQLException Error en Connect No suitable driver 

I'm not sure how to proceed...(?)

tia,

Peter

do you have the driver classes (ie. classes12.zip)
in your CLASSPATH? you can get the archive from oracle
web-site.

Make sure you are using the right version of the jdbc driver. Snag the one
from your oracle installation.

I haven't made any variations to the classpath, but if
I understand correctly the classloader make the class
available upon starting tomcat, given that within the
webapp realm. The class is in
/usr/local/jakarta-tomcat3.3.1/webapps/upload/WEB-INF/lib

*upload is just the name of the servlet

And then there will be much rejoycing and celebration....

This doesn't sound like good news to me.  (Good news for FreeBSD 5 though I 
suppose).   

How lean is the FreeBSD Java team right now?   Does this compromise the target 
of FreeBSD shipping a Sun-approved JVM at all?   I think everyone would 
probably love to know more about the people behind the project here.   

Also I would like to know whether the JVM patchset releases are pretty much 
frozen because of the work around KSEs.  I was hoping to see a more 
aggressive patchset release schedule (I would have expected us to be at 8 or 
9 by now) ... but it seems like we're just dealing with the status quo until 
FreeBSD 5.0 ships.  (That's my rough perception of it)

Cheers,

It's mixed, but they're kind of the same thing, so working threading issues are
pretty much essential for doing JVM hacking.

Basically, I need to continue with my career track and it's not logical for me
to narrow myself doing JVM internals programming. I never really got to do kernel
programming when I was at BSDi per se even though I was headed into the core
engineering staff.

The JVM was sort of a misguided suicidal test for anybody at any technical level
to see if I can handle it or not.

I think I won. ;)

Very lean. It's pretty much just Greg now part time. I'm still half working on
it since I'm around all the dependent systems, but I'd really like to get into
other more kernelly stuff at this time.

I talked to Jeffery Hsu about this on IRC and he thinks it's a good manuever.

I'll be more tightly integrated to pthreads issues until development gets
decoupled by a backport effort of -current's libc_r. That's my guess.

Hi Michael,

thanks again for your advice.  I went back to the docs, and found out I
was doing a lot wrong that I ahve since fixed.  I haven't gotten it
totally figured out, but I definitely fixed the codebase/rmiregistry
problem.

The Porting team is probably pretty lean at the moment.  Bill is working on
HotSpot and I'm working on JCK compliance.  I'm not sure on the status of
anyone else (feel free to let me know :).  This is all on a volunteer basis
and, at least for me, has to fit around work and everything else going on.

Almost all of the fixes that are in the repository (I can think of one
minor exception) are being installed as patches as part of the jdk13 port.
Bill's recent HotSpot work is the only really missing piece and that will
be addressed with patchset 7.  Its fine to want a more aggressive release
schedule, but there is no point releasing a new patchset if there isn't
really anything new to show.

That said, we're not bug free and I'll attempt to keep the bug fixes
coming as reports come in and fixes are found.  Right now, for instance,
I'm working on a bug in exec'ing an external process and waiting for it
to complete which is causing some of the JCK tests to fail bogusly.  If
I had a test case I'd post it, but I haven't narrowed it down yet.  I'll
also attempt to construct test cases for those JCK tests which are
failing and post them too so people can pitch in.  I can't just post
the tests themselves for obvious reasons.

For those who are interested there are currently 19 compiler failures
and 183 runtime failures that stand in the way of a binary release.  As
I mentioned above, many of the runtime failures are bogus and are due
to an exec bug (the tests pass when they are run by hand).

If anyone is interested in contributing, here are a couple of tasks in
no particular order:

1. Get native threads fully functional.  You probably need some pthreads
   knowledge for this, although I have none and I've hacked on things ;).
2. Start working on a port of 1.4.  I've imported the code but haven't
   had time to work on it yet.
3. Pick a bug from those listed for the jdk13 port and work on it.

If your primary interest is NetBSD or OpenBSD then work on making sure
things work there as well (OpenBSD in particular isn't even close with
respect to 1.3.1).

In short, its not a matter of status quo, its just that there hasn't been
a real justification for another patchset before Bill's HotSpot stuff.

Thank you, that's the sort of information I was curious about.

Unfortunately I can't help out here as much as I would like to;  I'm a systems 
manager by trade, too stupid at this juncture to understand that kind of 
code.

Fair enough.  My last email was not in any way a criticism.  You guys are 
doing above and beyond.   My hunch was that we didn't have many people on the 
team to move things along (and I was right).   I'm sure most people on this 
list who depend on the native JVM probably weren't sure of this either.

Perhaps if  this issue (# of committers/size of team) can remain a hot button, 
word might circulate, and we can get some more warm bodies added to the 
effort.   Without at least 2 more people in the mix, my guess is we won't be 
making progress.

I will check around to see if anyone I know can help out.

Cheers,

This is a real problem; as I understand it (and my understanding may be
flawed, or somewhat out of date) Sun _still_ haven't released* a
conformance testing kit, which basically means work has to be indirected
through the one person brave enough to have sold their soul to Sun :-(

Anyhoo, keep up the good work, etc.

I certainly didn't take it as a criticism :).  Just explaining the state
of play.  I may have been doing other committers an injustice, however the
only (FreeBSD) one I've heard from lately is Fuyuhiko-san, who had done
some tests with HotSpot and had a few small patches I believe.  More
active developers are always welcome though and would certainly make
things easier.

Well, progress will be slow at least :).

As I said above, extra help is always appreciated :).  My only general
comments are that people should be prepared to dive in and do some work
before they are given repository access (but please try and coordinate
whatever you are doing, through me possibly(?)).

Greg (et al.):

This seems like as good a time to ask as any ...

I am very good at *Java*, but adequate at best at C/C++.

I "know" C/C++, but I don't know how to use debuggers, don't have any
experience making system calls, etc.  This kind of hard-core practical
knowledge I imagine is important to what you are working on.  (Stuff like
"run it under gdb and tell me what happens" seems to come up, but I have
only the vaguest idea what that means and wouldn't know how to interpret the
output.)

Presumably there are some people with my skill set laying around.  What
would be the best way for *us* to help out (if there are any right now)?

-- David.

Right, the JCK suite is only available to Sun licensees.  Its not a huge
problem, it just means I have to construct some code to demonstrate the
failures rather than being able to just post the test.  Having said that,
you are correct in that it does mean all the testing work must currently
go through one person, which _is_ a problem in that it make me a
bottleneck :(.

There are a number of ways that I believe you (and others) could help. My
skillset seems to be close to yours, by the way. I have stated in previous
mails what people can do to help. Basically it involves creating detailed
problem reports of the existing problems. Another way is to try to reproduce
problems that people report and test out various configurations to narrow
the search down.

Let me suggest another way to help.

I have written a number of web pages (http://www.kjkoster.org/java/) with
howto's and problem descriptions and porting help. If someone would help me
get that text up to date to the current patch sets and expand with
descriptions of known problems and remove the problems that have been fixed.

I would like my web site to be more up to date and provide useful
information for would-be porters. I would like there to be a list of
currently known issues with the various JDK's and the status of the current
ports on the various platforms.

If you are interested, please tell me and we'll work our a way to let you
edit my web pages.

This would help the porting effort in general, because you'd document the
problem that exist

The reason why I am not doing these things is simple: lack of time. I have
two jobs already. :)

I might have reported it already, I don't remember. It's a weird problem:
I have a multithreaded application, one of the threads reads from stdin 
using BufferedReader. When I run this program in xterm, the stdin thread 
blocks and stops all other threads. Running the same program w/o X (on 
console) -- no problem. It's jdk1.3.1p6 on 4.5-STABLE. 

OpenOffice question: OO can not use native jdk1.3.1, only Linux. Is this 
because of native threads or something else?

Whoa. OO actually works on FreeBSD? natively? since when? or are you 
running the linux bins in compat mode?

if you are running the linux bins, then your going to be running it 
against the linux jdk because it's part of your 'world' and the native 
stuff isnt.

if you are running OO native, tell me more, because i'd really like to be 
using it ( i use it at work on my linux box and none of my windows 
brethren are any wiser because the document exchange is great ).

i dont have any idea what's going wrong (other than to say that billh 
moved to current for some probably salient reason :-) ).

but i'd certainly try to make time to try this because it's probably 
something that i could narrow down a bit....

Could you maybe construct a small test program that demonstrates this?

I've no idea.  If it works with the Linux JDK then it appeals to me that
its exec'ing it and it should work just as well with the native one.  Not
having upgraded to 4.6, I can't even build and test it.

I kind of expected that question... I'll put it on my todo list. It's

Yes, that's what I'd assume, but on the other hand OpenOffice seems to be 
very tightly integrated with Java through JNI calls. Doesn't make any 
sense :(

P.S. John, I'll answer your question here to reduce list pollution:
Yes, OpenOffice runs natively on FreeBSD 4.6-STABLE. I think it should run 
even on 4.6-RELEASE. I've been trying to build it from ports for the last 
couple of weeks w/o any success, finally cvsup'ed yesterday and it worked!
Some things still crash, but SWriter seems to work.

Thats a valid question :).  Unfortunately there isn't necessarily a lot
that people in that boat can do.  Here are two suggestions off the top
of my head.

1. Use the native JDK.  The more people using it hopefully the more bugs
   can be found.  If you do find a bug, please report and it and preferably
   try and narrow it down to as simple a test case as you can.  The down
   side is that bugs may not be fixed as soon as you may like, but it does
   help.

2. If you're really interested, try your hand at working on the JDK
   source.  Yes, you may have to learn more about C/C++ (or even assembler)
   but a bit of persistence can work wonders.  Just pick a problem and
   go at it!  Ask questions when you get stuck, you may be surprised at
   how happy people are to help when you're having a fair dinkum go at 
   things.

i think this is a good moment to ask...

Isn't FreeBSD POSIX compliant? or it is just that Java isn't written in 
a very portable way? what issues can come on when changing from linux to 
freebie? from my experience, making a program to build and run without 
issues in both environments is just to write ANSI C/C++ and POSIX.

I'm not very good in Java, but I'm fairly nice in C++ programming (but I 
have no problems working with C).  I also have a problem on working with 
debuggers, but I'm not as old as for not to learn.  If in any way I can 
throw my two cents on the table, and it is helpful, please feel free to ask.

-  have fun

Daniel Valencia

It's a persistence kind of thing. You can only develope it by intense
work like any other displine.

Raise the skill set to the level needed to do this work. Most of it is a
mental problem, but once you get past that it's not as hard as one might
think.

Overall, I think the project is in good condition. I intentionally made
sure (with great pain) that the HotSpot core would at least be
functional enough, so that it could be then maintained by folks without
the diversity of knowledge that I have about libc_r + HotSpot.

That's a good setup for doing a 1.4 port since -classic is missing and
was one of the major drives for me to do it. It lays the foundation for
future work.

You're actually not looking too bad. I don't believe the Linux JDK even
passes all tests from the last time I tried it about a year ago.

That's the last thing I'm going to do in the context of JVM hacking and
a natural transition into libc_r/KSEs for me.

Getting (2) would be cute, but all the technical aspects of this require
that you have a lot of persistence, competency with C and langauge
runtime internals.

Hi all,

I really like some of the concepts of COM in the Windows environment,
like a published interface, a GUID, and built-in versioning.  I
understand Java Beans are the Java version of components, but I believe
they work a bit differently.

Is there anything like COM binary components in Java?

maybe you should look at enterprise java beans? i think they are a bit more
lika COM objects.

Nice site.   

User-contributed docs are obviously wonderful when there isn't anything in the 
FreeBSD Handbook to speak of.  The pages that are in the Handbook now are 
quite dated, only specific to JDK 1.2.  Differences abound since then.   For 
instance, (if I'm not mistaken) the JDK 1.3 is based on the Linux source, 
unlike JDK 1.2 which uses the Solaris source.

I would be willing to help out on an effort to take your documentation as a 
base, roll it up to the JDK 1.3 level, and make an effort to update it with 
all the news that is current to the JDK 1.3 patchset.  

Finally, we would need to take that and express it in DocBook markup, and send 
it to a committer on the FreeBSD Documentation Project (FDP) to validate it.   
I would have reservations contributing docs that are not posted to the 
FreeBSD Handbook.

As an aside...
It would be useful to get the GNATS maintainer to add a new category in the 
database for "java".  (If that is even permissable.)   By doing that, we 
could minimize some confusion about where to file Java bugs.  We would move 
all the existing PR's under "ports" into "java", and also eliminate the need 
for hosting a buglist on a foreign site.

That's not to say your site and efforts are unappreciated (I wouldn't want you 
to think that).   My opinion is that we should formalize the relationship 
between FreeBSD and Java by providing current, accurate documentation in the 
Handbook; and also make sure that _all bugs_ are filed as PR's in FreeBSD's 
GNATS database.

This will free up the people doing the coding from being distracted with 
high-level communications.   The signal-to-noise ratio isn't always good on 
this list; I believe that's because there's not a good base of java 
documentation in the Handbook.  Bill, Greg, Nate and others seem to be 
responding to questions on the overall status of the JDK port more than 
tackling the fundamental issues at play.  

If we can shelter them a little bit from that noise, they would probably have 
more time to code and debug; and it would also create an environment more 
suitable for new committers.

Just my thoughts anyway.  Let me know if these ideas are amenable to you.

Cheers,

with the risk of being overly flip; you like COM because you haven't 
written any full size multiple developer products with it yet!

it get's very fragile and fiddly when you get up to the multiple 100's of 
interfaces.

i could explain some more practical and pragmatic challenges associated 
with COM ( which i agree is pretty darn nifty in theory ), but this is the 
freebsd java list.

umm, CORBA? are you trying to interoperate with a non java app? any non 
java app has to speak the same binary interfacing standard.

you could probably develop a COM-ish thing, but really, it's less of a joy 
than you might think.

Or use LGPLed UNO framework from Sun's OpenOffice. Has bridges for Java,
C++, etc. Looks quite powerful.

We have quite a few in ours, but not hundreds.  There are basically 2
things I like about it:

GUIDs, so if I say I want a certain version of an interface, 
the GUID guarantees it is.

It breaks down to straight function calls for in-process servers.  No
overhead, less work than CORBA.

Please, email me privately.  ;-)

What I really want is the total separation of functionality that
components can provide.  Now, the ugly part of COM is the type library.
That's the necessary link.

What can I do in Java that would allow one class to dynamically bind
(early) to another?

I'm rather convinced at this point that components dramatically improve
project organization beyond a certain point.  My current project uses a
great deal of inheritance, but components really separate functions into
contract interactions.  How can I do this in Java?  Do Interfaces work
well enough for this?  Is there a Java binary equivalent, so the binding
takes place at run-time rather than compile-time?

Would a network classloader do what you want? There'd be still quite a
bit of work to do to handle the interaction.

really? promise? nobody ever adds a new method to the same interface? your 
dev team get's it perfect the first time? if they dont get it right the 
first time ( a typical case in any development effort ) what happens then? 
new interface and new guid? or does the new method just get added to the 
same guid?

has anybody been dumb enuf yet to think that if they dont tell anybody
about a method that they added, then it's 'secret'. hoho. it's secret
until somebody runs that broken-ass* ObjectView?(is that it, i cant
recall)  thingy and gets themselves a new header and idl file complete 
with the 'secret' methods.

*in vc6, which was the last platform i used COM on extensively, the idl 
wouldnt compile because it was broken. i actually got hired into a new 
group at my old job based on the fact that i figured this out and fixed 
the mis-emitted idl so i could use it.

hmm, it breaks down to a call to a function pointer in a vtable, so it's 
not *quite* that simple...but certainly less involved then CORBA, at a 
cost of being trapped in a single OS. There *was* a DCOM port to a few 
things, but it met with less than enthusiastic support.

yes, and you may eventually find yourself groaning vigourously when you 
realize that a needed interface change is going to require you to 
trivially edit and rebuild a whole bunch more files than you would have 
otherwise because of this additional requirement.

this is what i meant about being fiddly.

with the caveat that i have only read about it and not coded with it, the 
broker idea in corba seems to me to be a better solution; u do it your 
way, he does it his way, code the broker to sort it out.

organization is more rigidly enforced, but *changes* to organization are a 
more annoying pain in the ass, and in a development environment ( *not* a 
*product* interoperability environment ) that counts for a lot.

eek, worst of both worlds in my opinion, but it's only my opinion. now you 
have to go back and fiddle with even more things if you decide that you 
want to push back some funtionality into a parent class, or to completely 
rethink the problem (refactor).

I think that this at some point becomes a /usr/X11/bin vs usr/bin/X11 
issue, which is my shorthand for the idea that the pain is the same, you 
just are choosing your pain budget differently then i do.

i am sure that over the course of the next few weeks, other things will 
come up, but i think that i've hit the hi points from my perspective.

> How can I do this in Java?

i'm guessing EJB, but that's a guess absent experience.

> Do Interfaces work well enough for this?

no, i dont think so, because the implementation of the classes that you 
are passing as arguments to the methods that implement the interfaces are 
uncontrolled.

let me know what you come up with.

to return to my thoughts on COM, i think that it's really quite cool for 
defining inter *product* interfaces. 

for example, it's tres bitchin' to think of being able to add a new secure
vpn mail protocol to outlook as a COM object and have it automagically
show up ar a replacement toolbar for the default toolbar in outlook.

it's also worth recalling that WinAmp and XMMS and gimp and anything that 
has 'plugins' have a similar interface.

but, to return to my outlook example, *Nobody's* Done It!

furthermore, nobody sell's 'improvements' that i am aware of ( by that i 
mean a 'thing' that implements a GUID and is cooler than the original 
implementation so you want to buy it and replace the old one.

COM was a solution to a problem that nobody has really seemed to care 
about

MSFT continued to fiddle with it so that it would be simpler to use, but 
they've basically given up. 

there is an absolutely hilarious verity stob essay that i shared with some
of my other COM aware collegues:

http://www.ddj.com/documents/s=1504/ddj0108vs/0108vs001.htm

hope u get a laff. it's been fun to think of this again...

Is this buglist publicly available? If so, where?

Using Mozilla 1.0 the java plugin (1.3.1-p6) doesn't use the proxy
information from the browser, but tries to download the applet
directly.

For example, I go to
http://java.sun.com/j2se/1.3/docs/relnotes/demos.html
and try to load one of the demo applets. I run netstat and
see

Proto Recv-Q Send-Q  Local Address          Foreign Address        (state)
tcp4       0      0  192.168.64.4.2366      192.18.97.71.80        SYN_SENT
tcp4       0      0  192.168.64.4.2365      192.168.64.6.3128      ESTABLISHED

The web page gets loaded via the proxy (on port 3128), but the applet
never gets loaded because it is being loaded via a direct connection
to port 80 on 192.18.97.7

Is there some way I can kick the plugin to use the proxy?
