Synopsis: remove opera ("pkg_remove -vf" if appopriate), remove any
previous versions of jdk 1.3.X...reinstall the latest linux-jdk 1.3.1
(after doing a cvsup update...things have changed in the last week or so),
make sure that /usr/local/share/opera/ is completely gone (pkg_remove
won't remove the plugins directory if you made non-default changes like I
did...), then install /usr/ports/linux-opera/ (opera 5.05-tp1) again.
I'm viewing the chat applet on your home page via Opera right now! I can
also view the applets on the start page at java.sun.com. However, the
chat.yahoo.com pages still appear not to work.
Using the tip I learned from http://klop.yi.org/~ronald/opera/ about the
OpenMotif RPM (duh...I tried using the .tgz file and extracting the files
to /usr/compat/linux manually), I finally got operamotifwrapper to
recognize libXm.so.2. I had previously installed the OpenMotif source
code port and the linux .tgz file which of course didn't work!
On a side note, one of my employers uses Java, XML/XSL, and Tomcat/JSP's
quite heavily on their web pages. The webserver (unfortunately) has to
run on Linux because of the currently poor *BSD Java support. However,
great advances have been made in the past two weeks with the native *BSD
JDK 1.3.1 port. In fact, for the first time, I'm able to install and
execute our JSP pages without any linux jdk emulation. Performance still
sucks compared to the linux webserver, but it is much better than the
performance of any of the linux-based jdk's (IBM's or Sun's). Kudos to
all those working on the *BSD java port.
It appears that the primary performance difference is due to the fact that
Tomcat under linux starts multiple (threaded?) JVM's (with NO changes to
the tomcat startup scripts)...while the FreeBSD native 1.3.1 and the
Sun/Linux-emulation JDK only start one. The IBM/Linux JDK 1.3.1 starts
multiple JVM's, but the tomcat process is not able to communicate with any
of them (even with linprocfs). The aforementioned Linux (native) server
showed the exact same performance problems under JDK 1.2.2 (only a single
JVM loaded) but dramatically improved under JDK 1.3.1 (no changes to
tomcat or jsp pages...just the stock version upgrade/install). A page
that took 35 seconds to load under JDK 1.2.2 took 9 seconds with JDK
1.3.1...but that same page takes 20 seconds to load on the *BSD native JDK
1.3.1 (on a box with 40% better CPU horsepower than the Linux box).
I look forward to the day when I can finally replace that Linux box with
Open/FreeBSD ;-)
