After 5 years I have returned to jboss because I wanted to evaluate JBPM (I’ll write about it later). But this I already knew pitfulls of JEE . Avoid EJBs!.
I downloaded latest stable version of jboss and run it empty to test: no errors, perfect!
I configured my ide (idea 7.0) and run it with a simple jsp application . Awesome still no error. Idea 7.0 realy has a good integration with jboss. Only imported point i you should name exploded folder name with proper suffix (.jar/.war/.ear)
At this what u have out of box :
This means when u move from tomcat/jetty to jboss you should change maven dependecies of these projects. They are already ready and running
