(on Ubuntu)Does anyone have Tomcat6 serving servlet pages to Apache2?

[qmacg]

On Ubuntu Linux, I'm having a hard time configuring Apache2 with Tomcat6. Does anyone have a working version of Apache2, Tomcat6 and Mod_jk? Perhaps someone could provide some samples of their working server.xml, workers.properties and /etc/apache2/apache2.conf files. When I bring up http:localhost/ on my browser, the default Apache .html displays properly and when i bring up the

http://localhost:8080/examples

pages, I can run the servlets properly in the browser. Any help would be appreciated..:

(I've pasted some of my config files below...)


Here is my mod_jk.conf file... at /etc/apache2/conf.d...:
JkWorkersFile /etc/libapache2-mod-jk/workers.properties
JkMount /*.jsp ajp13
JkMount /servlet/* ajp13
Alias /examples "/usr/share/tomcat6-examples/examples"
<Directory "/usr/share/tomcat6-examples/examples">
Options Indexes FollowSymLinks
</Directory>
<Location "/examples/WEB-INF/">
#AllowOverride None
deny from all
</Location>
Alias /BookNook "/var/lib/tomcat6/webapps/BookNook"
<Directory "/var/lib/tomcat6/webapps/BookNook">
Options Indexes FollowSymLinks
</Directory>
<Location "/BookNook/WEB-INF/">
#AllowOverride None
deny from all
</Location>


Here is my worders.properties file... at /etc/libapache2-mod-jk...:
workers.tomcat_home=/var/lib/tomcat6
workers.java_home=/usr/lib/jvm/java-6-sun
ps=/
worker.list=ajp13

# Define a worker named 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
# Defining a worker named inprocess and of type jni
worker.inprocess.type=jni
# Additional class path components.
worker.inprocess.class_path=$(workers.tomcat_home)$(ps)server$(ps)lib$(ps)tomcat-ajp.jar - Changed this line to match location of library.
worker.inprocess.cmd_line=start
worker.inprocess.class_path=$(workers.java_home)$(ps)lib$(ps)tools.jar - This line based on something I read. (Also modified to match installation)
# Unix - Sun VM or blackdown
worker.inprocess.jvm_lib=$(workers.java_home)$(ps)jre$(ps)lib$(ps)i386$(ps)server$(ps)libjvm.so - Changed this line to match location of library.
# Setting the place for the stdout and stderr of tomcat
worker.inprocess.stdout=$(workers.tomcat_home)$(ps)logs$(ps)inprocess.stdout
worker.inprocess.stderr=$(workers.tomcat_home)$(ps)logs$(ps)inprocess.stderr

Here is the server.xml file below in /etc/tomcat6 directory...:

I went down that path but instead use mod_proxy and mod_proxy_ajp -- it accomplishes the same goal and is much simpler.

Let me know if you need further info.
