How can I install JiveMessenger with a WebApplication?

I found that all the documents for install guide is for standalone mode,if I want to install it into Tomcat 5 or Other J2EE Server supporting JDK1.5,how can I do?Help please.

Official support for deploying inside an app-server will be coming soon. We’'re going to have a special release that comes packaged as a WAR file. For now, we recommend deploying as standalone.

Matt
