Hi everyone. This is a long message so please bear with me. :)
I am attempting to get tomcat running 'inprocess' from mod_jk2 under
apache on solaris. I am getting random results, which is very annoying,
hopefully someone can help.
Versions:
os: sparc solaris 8, 32 bit
apache-2.0.44
tomcat-4.1.24
mod_jk2 from jakarta-tomcat-connectors-4.1.24-src
java - j2se-1.4.1-b21
I wish to use the inprocess method of running tomcat because I would
like my users to not have to maintain a 'running' tomcat server as well
as apache.
I have a few problems, which probably stem from a larger problem.
When I start apache, tomcat doesn't always get started, but does
sometimes! When starting apache I see in the error_log:
[Wed Apr 02 13:59:13 2003] [error] workerEnv.initChannel() init failed
for channel.jni:jni
[Wed Apr 02 13:59:13 2003] [error] workerEnv.initWorkers() init failed
for worker.jni:onStartup
[Wed Apr 02 13:59:13 2003] [error] workerEnv.initWorkers() init failed
for worker.jni:onShutdown
[Wed Apr 02 13:59:13 2003] [error] mod_jk child init 1 -2
I see a group of these messages for every apache thread that is started.
Most of the time I get a bunch of these and tomcat does not get
started. I then stop apache, then restart it... if I am lucky I may
only get a couple groups of these failure messages then a success,
tomcat gets started:

I also see activity in my tomcat based application log. I have
identical results with the examples context.
Now, when it DOES load I only occasionally get a valid response. I hit
http://localhost/examples/servlets/index.html and see the page
displayed, only with a few broken images. I do a shift-reload and some
of the proken images appear, but others become broken. I hit
shift-reload a few times and I get the occasional internal server error
from apache. When either of these occur I see in the error_log:
[Wed Apr 02 14:14:37 2003] [error] lb_worker.service() all workers in
error or disabled state
[Wed Apr 02 14:14:37 2003] [error] mod_jk.handler() Error connecting to

I have read other people's posts about mod_jk2 and inprocess but have
not seen any reported problems such as these.
Now for some information on my configuration.
