Hi Jimmy,
I have solved some of the problems you are facing. I can get Apache
to startTomcat via JNI cleanly. The TomcatStarter problem was solved
by putting $TOMCAT/bin/tomcat-jni.jar on the path. I have couple
of startup servlets which were correctly loaded. I use Cactus so had
to put the log4j*.jar on $TOMCAT/server/lib, once I did that all
my startup servlets came up fine.
But when I hit Apache with a request meant for a Tomcat hosted JSP/Servlet, I get the error below. I tried Apache 2.0.43 since the
pre-built mod_jk2.dll on Tomcat site was compiled with 2.0.43 and I
get the same error. Attached are the jk2 and worker2 files.
Note standalone Tomcat works fine with the web.xml etc. So the culprit
must be worker2 or jk2 properties file. Can't seem to find any docs
on the syntax of these two files. Can you send your files. Mine
are attached.
No matter what I do, always the same msg in Apache errors.log. Close
to giving up on jk2 and planning on trying jk or mod_webapps. It
seems most people are not running Apache2+TC4 in-process. I would hate
to loose performance by going out of process, but if none of the JNI
modes work that I guess will be the last resort

I just got Apache 2.0.44 and Tomat 4.1 working with a little twist. I think
we are trying to accomplish the same thing. I think server.xml is not the
culprit. jk2.properties and worker2.properties are. Also web.xml in Tomcat
home as well as the webapp could affect servlet and jps execution. What do
your jk2.properties and worker2.propeties look like?
My problem is that I cannot get Tomcat fired up properly from Apache without
first running Tomcat manually. I keep on getting 'HTTP Status 503 - Servlet
invoker is currently unavailable' error if I don't run Tomcat first. Of
course this would defeat the purpose of using Tomcat as worker from Apache.
My other problem is that I cannot get org/apache/jk/apr/TomcatStarter
started properly unless I specify whole bunch of jar files using classpath
in [vm:] directory. It looks like jvm that Apache runs have trouble with
class path in my environment. But I don't know how to set it. I am
interested in knowing how you get TomcatStarter working.
Other than those 2 problems, my Apache can serve up html, jsp, as well as
servlet in my webapp fine.

Re-posting with the relevant files attached.
Keep getting the error from mod_jk2 about Error connecting to tomcat
120000.
Using Apache 2.0.44 with Tomcat 4.1.18 on Win2K. Checked my config 1000
times everything looks
good. Is this a know issue ? Is there ant doc/reference on
workers2.properties ?
Attached are my config files.
