mod_jk and tomcat virtual hosts not working properly

Hi,


First of all I would like to mention that this is my first post on this list, I hope that this question is posted in the right place. I have tried finding a solution for my problem, but it either doesn't exist, or my limited brain can't manage to figure out how to do it (I strongly hope it is the latter).

My issue is with the mod_jk plugin. I want to redirect my subdomain requests jira.example.com to a tomcat 6 virtual host called jiraapp.

If I call the subdomain jira.example.com Im always getting the default tomcat 6 host called localhost.

I tested every part:
1.) mod_jk: if i change the workers name in either workers.properties or under my enabled-site <VirtualHost> or if i change the mapping to my virtual host (/etc/hosts: 127.0.0.1 localhost jiraapp) apache doesnt start.
2.) if I do a lynx jiraapp:8080 on the machine it works and shows the right webapp.

But if I access jira.example.com I always getting the default root-webapp of tomcat 6. So theres no difference in calling jira.example.com or example.com:8080.

My conclusion is that I sucessfully set up mod_jk, apache2 virtual hosts (for the subdomain) and tomcat virtual hosts, because everything works fine if tested alone. But if I try to use everything together and remotely it doesnt work.

Help would be appreciated.
