Hello,
I'm trying to integrate Apache and Tomcat and am having a devil of a time.
It's probably something simple, but I've read the documentation and several
"how-to" guides and searched the archives but didn't find anything that
helped.
The particulars are below. Apologies if this is obvious, I'm a newbie to
Tomcat.
Thanks for any help,
--Webb Stacy
MY SETUP:
Basics - all are working
Red Hat Linux 7.1 on a Virtuozzo Virtual Private Server on x86
architecture
Apache 1.3.26 - working
Sun JDK 1.4.1_01 - working
Tomcat 4.1.18 - installed from rpm - working on port 8080
Enviornment variables:
JAVA_HOME is /usr/java/j2sdk1.4.1_01
CATALINA_HOME is /var/tomcat4
JASPER_HOME is /var/tomcat4
CATALINA_TEMPDIR is /var/tomcat4/temp
JK stuff - not working
mod_jk-api13-1.2.2-1 - installed from rpm
mod_jk.so in /usr/lib/apache
httpd.conf - no changes made, these lines were already at the end of the
file
(It appears that HAVE_JK is defined when Apache is started,
though I don't understand the mechanism.)
<IfDefine HAVE_JK>
LoadModule jk_module modules/mod_jk.so
AddModule mod_jk.c
Include /etc/httpd/conf/mod_jk.conf
</IfDefine>
workers.properties (in /etc/httpd/conf)
workers.tomcat_home=/var/tomcat4
workers.java_home=/usr/java/j2sdk1.4.1_01
worker.list=ajp13
worker.ajp13.port=8009
worker.ajp13.host=localhost
worker.ajp13.type=ajp13
worker.ajp13.lbfactor=1
worker.loadbalancer.type=lb
worker.loadbalancer.balanced_workers=ajp13
server.xml changes

relevant lines from mod_jk.conf
JkWorkersFile /etc/httpd/conf/workers.properties
JkLogFile /var/log/httpd/mod_jk.log
JkLogLevel info
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
..and a bunch of aliases, mounts, and protection of WEB-INF
directories...
To reconfigure,
Apache and Tomcat were stopped,
then Tomcat was restarted,
then Apache was restarted after 30 sec. wait
THE RESULTS:
Apache serves /index.html successfuly
Tomcat serves mydomain.com:8080/index.jsp successfully
mydomain.com/index.jsp and /servlet/ get "page contains no data"
mydomain.com/examples/jsp and mydomain.com/examples/jsp/index.html get
403 permission denied
no output to mod_jk.log
the end of catalina.out shows

startElement
SEVERE: Begin event threw exception
Catalina.start: java.lang.ClassNotFoundException:
org.apache.ajp.Tomcat4.config.ApacheConfig
...and a stack trace...
(though a jar tvf of $CATALINA_HOME/server/lib/tomcat-jk.jar shows
it's there)
the end of the Apache error log shows
