How to deploy different web applications on different ports

[mocha_java]

Hi,

I am using JBoss 4.2.1GA.

I have two web applications, say, one is public.war, and another is private.war. I need to deploy public.war to the port 8080 and private.war to port 8081.

How can I configure JBoss to make it work?

Thanks in advance!

One more clarification:
public.war cannot be accessed through 8081, and private.war not through 8080
