Configuring mod_jk, and the notion of "webapps"
I have been having trouble getting mod_jk to work. After having Googled
and read various information on configuring mod_jk (that's the first
problem -- we need good documentation without having to Google), I
settled on this link which is a pretty good HOWTO:
http://www.meritonlinesystems.com/docs/apache_tomcat_redhat.html
The problem is, once I got everything setup, things didn't work as
expected. Before going into a long diatribe about all the potential
issues, what I checked, etc., I want to inquire about the notion of this
document's advice about your "webapp", as mentioned in http.conf and
server.xml configuration, and as shown in step 5 of this HOWTO, in
directory creation. The document instructs you to create the appropriate
application directories as follows:
mkdir /home/tomcat/webapps
mkdir /home/tomcat/webapps/{YOUR_DOMAIN}
mkdir /home/tomcat/webapps/{YOUR_DOMAIN}/logs
mkdir /home/tomcat/webapps/{YOUR_DOMAIN}/{YOUR_APPLICATION}
mkdir /home/tomcat/webapps/{YOUR_DOMAIN}/{YOUR_APPLICATION}/WEB-INF
mkdir /home/tomcat/webapps/{YOUR_DOMAIN}/{YOUR_APPLICATION}/WEB-INF/classes
In the httpd.conf, the virtualHost directive setup recommended is as
follows:
<VirtualHost 127.0.0.1:80>
ServerAdmin webmaster@{YOUR_DOMAIN}
ServerName {YOUR_DOMAIN}
DocumentRoot /home/tomcat/webapps/{YOUR_DOMAIN}/{YOUR_APPLICATION}
ErrorLog /home/tomcat/webapps/{YOUR_DOMAIN}/logs/error_log
CustomLog /home/tomcat/webapps/{YOUR_DOMAIN}/logs/access_log common
JkMount /*.jsp wrkr
JkMount /servlet/* wrkr
# Deny direct access to WEB-INF
<LocationMatch ".*WEB-INF.*">
AllowOverride None
deny from all
</LocationMatch>
</VirtualHost>
and in configuring the Tomcat context, the configuration recommended is as follows:
<Context path=""
docBase="{YOUR_APPLICATION}"
reloadable="true"
debug="0"/>
I don't get the {YOUR_APPLICATION} part of this. Basically, I have a domain, and from it, I will be serving the contents of one or more web applications.
These web applications of course are WAR files. The directory creation instructions look as if you would be creating the exploded WAR structure manually, and the virtual
host configuration and context configuration appear to be addressing a particular WAR. This doesn't make sense to me. All I want to do is forward all requests with a particular
prefix to Tomcat, regardless of the web application, and based upon the prefix, tomcat will determine which web application will respond (just as if you were using Tomcat without
Apache httpd).
Can someone give me a heads up on how to configure this? Thanks!

I agree with you. We need a better documentation, but at the
end of the day no one ever wishes to contribute.
Mod_jk is open source project and without help from the
community I'm not sure how it's quality can ever rise.
So, I would suggest that if you come to an idea how
to extend the existing docs to the next level, simply
write a small email and send it to the dev@tomcat.apache.org
The guys there will be happy to commit that.
Best regards,
Mladen.

Vanessa,
Thanks for the resource. However, as I've been told, in-process/JNI
is/will be deprecated and isn't recommended with Tomcat 5.5 and Apache
2.x, and it appears that this particular configuration is trying to do
that. Perhaps I've heard wrong. But I guess the confusion underscores
the lack of documentation surrounding this area of Tomcat.

Brad,
I found a good how-to that helped me put mod_jk to work.
www.howtoforge.com/apache2_tomcat5_mod_jk
It's very simple, and it works.
