IntelliJ IDEA 4 integration with Tomcat / JBoss ... HowTo?

I see in the IDEA 4 documentation screenshots JetBrains has jboss setup as a Global Library. Is this the prefered way to integrate jboss with IDEA?

If this is so, what steps are necessary to add such a jboss global library?

Are there similar instructions for Tomcat integration?

I am looking to integrate JBoss & IDEA as tightly together as possible in a way that is most agreeable with IDEA. Just as a sidenote, I am working on Mac OS X 10.3.3.

Thanks in advance for any possible assistance.
