Apache/Tomcat/mod_jk. How to make several urls to point to different tomcat instances?

My case:

I have several webapps running on my tomcat server like this:

demo.mys开发者_StackOverflowerver.com/application1

demo.myserver.com/application2

demo.myserver.com/application3

This is what I want:

Application1.mydomain.com to point to demo.myserver.com/application1

Application2.mydomain.com to point to demo.myserver.com/application2

Application3.mydomain.com to point to demo.myserver.com/application3

This is what I have done:

1. I have set my DNS server to point Application1.mydomain.com and so on to my servers IP address.

2. I have set up apache webserver, apache tomcat6 and the JK2 plugin to make them communicate.

3. I have configured a virtual domain for all my domains in httpd-vhosts.conf and enabled it in httpd.conf.

httpd.conf:

Include conf/extra/httpd-vhosts.conf

httpd-vhosts.conf:

<VirtualHost *:80>
ServerName Application1.mydomain.com
JkMount /* workername
</VirtualHost>

4. I have verified that everything works fine with just apache.

My problem is when I try to use the JKMount to redirect the requests to my application. How can I do this? Or is it a better way of doing this?
