mod_jk2 inprocess tomcat / apache

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:

[Wed Apr 02 14:01:00 2003] [error] workerEnv.initChannel() init failed

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

error or disabled state
[Wed Apr 02 14:14:37 2003] [error] mod_jk.handler() Error connecting to 
tomcat 120000


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.

In my server.xml I do have my Coyote/JK2 AJP 1.3 Connector listening on 
port 8009, the default.  I am not even sure if I need this for inprocess 
but I am not aware of how else pache may communicate with tomcat.  Can 
anyone shed some light here?


Thanks for reading this!

Are you providing a user name and password?
I am not familiar with this driver, but with the IBM DB2 driver a property 
of prompt=false is also needed.
