Subject:   can't run Tomcat correctly using linux-jdk13 and apache
Message-ID:  <3A52A8B2.1FE4CBA2@transbay.net>

next in thread | raw e-mail | index | archive | help
Using apache 1.3.9 with jakarta-tomcat 3.2.1 or 3.1.1 and the freebsd port linux-jdk13,
follow the directions that tomcat has to be running before apache is (re)started,
tomcat comes up on its own evidently okay (no errors to the logs).

Go to (localhost):8080 and tomcat displays its page.
Execute the examples - some may work, but ultimately running an example
produces the following error message:

Java HotSpot(TM) Client VM warning: cannot uninstall alt signal stack

numerous times, the access through the browser for the example hangs with a wait-cursor,
and tomcat examples no longer function at all. Symptoms also include "(java)" zombies
in "ps ax".

*****

We thought it was that the original Linux jdk1.3 for Linux handled signals differently
and the FreeBSD port of this JDK would fix this problem, but evidently not?

Using tomcat 3.1.1 the "cannot uninstall alt signal stack" message comes out every 5 seconds
after tomcat is started. Using tomcat 3.2.1 the message appears when a 'bad' example
is accessed, with references in the tomcat logs to "cannot ... null reference (null/null)"
complaining about null references in the java code.

*****

Can we run this on FreeBSD? linux-jdk1.3 + tomcat 3.2.1 = newest Jserv support?
Or are we forced to use Linux?

Anyone who's gotten this working, please let us know. Thanks.
