[Tomcat6/mod_jk/Apache2.2] JkMount and Url patterns

[Nikhil Lanjewar]

Hi,

Recently I explored a lot about using mod_jk with Apache Web server and Tomcat. Purpose was to expose only port 80 to the internet cloud and handle maximum types of requests on the same port. I could successfully redirect my requests for Tomcat6 using apache and mod_jk. However, there's a limitation that I could find and it would be great to have some suggestions in this regard.

JkMount /servlet/* worker1

Assuming that worker1 has been configured with type=ajp13 and host=example.com, this shall map all the requests of the pattern http://example.com/servlet/* to http://example.com:8080/servlet/*

Now I go ahead writing similar configurations for servlet1, servlet2 and servlet3 with all the url patterns being handled by worker1.
Let's say there are many such servlets hosted on a single Tomcat and I want to avoid writing several configurations by having a context path set for this instance. Something like,

JkMount /tomcat/* worker1

should map http://example.com/tomcat/servlet/* to http://example.com:8080/servlet which, currently maps to http://example.com:8080/tomcat6/servlet/* and gives a 404 Not Found (obviously).

I perceive the above as a combination of Proxy and mod_jk but am unable to figure out the exact configurations that are required to achieve the same. Is VirtualHost of any use in this scenario? Can anyone please provide some explanation?
