Both WebLogic and JBoss are J2EE compliant application servers, so you can move web apps from one to another without big headache. There are some server specific deployment descriptor xml files, though.
The easiest and fastest way to learn JBoss, IMO, is to follow their 'Getting Started Guide' in Documentation section.
