Drools Fusion and Java EE

Question

What are the best practices for using Drools Fusion on a Web/Enterprise Application? Do you know of any useful document?

I've looked through the examples on JBoss (http://download.jboss.org/drools/release/5.1.1.34858.FINAL/drools-5.1.1-examples.zip), but they are Desktop Applications. I don't understand how to keep a Drools session "running" like that on a server.
