Website running on tomcat talking to another website on same machine but different server

Question

I have two servers installed on my machine, Tomcat and Virgo, (an OSGi webserver) that run on different ports. I need a website deployed on Tomcat to link to another website deployed on the other server (which is not mapped to any address), how can I do this? Resolving client side the ip address of the server? What is the correct approach? Thanks.

Requirement is: The user browsing one app will need to be able to click on a link to the other app.
