How to access port 8080 of JBoss Package

I think it is a stupid question, but bother me several days.
After I installed JBoss Package 6.1 for IS 6.1,
I can’t get access to [url]http://localhost:8080/WarAndPeace/displayWarAndPeace.jsp[/url] work.

Besed on the jboss-web.xml :
… <security-domain>java:/jaas/webMethods</security-domain> …
I guessed I can login using ‘Administrator/manage’.
But it didn’t let me get in.

What did I miss?
