Dynamically point domain in Apache to application running on Tomcat

Question

Hi all,

I have question. Let's assume that I have API which allows me to add dynamically add DNS records. Now, I would like to run simple application on Tomcat and put Apache in front of it, so that any domain added to DNS pointing on this Apache would be served by application running. I read a bit about Dynamically Configured Mass Virtual Hosting on http://httpd.apache.org/docs/2.0/vhosts/mass.html but this seams would work when domains would point to some directory, when usually I was using mod_jk to use Apache and Tomcat together.

Please forgive me if I am asking about something obvious for administration gurus, but I do not have to much experience with this subject.

Thanks in advance!
