Looks like the current version is JBoss 4.0 - looks to me like this is
J2EE 1.4?  I may have the ability to change this in the future but
this is what the current view is.

I've seen the '@' element in a tutorial I'm working through:
http://programming.manessinger.com/tutorials/an-eclipse-glassfish-java-ee-6-tutorial/

In the code I see a lot of classes called 'XxxHome' that inherit from
javax.ejb.EJBHome.  No use of '@'.  So I gather I need to learn the
hard way too...

Got it installed both from the EE Jdk and with Eclipse as some sort of
package eclipse thing (eclipse wasn't able to restart the glassfish
domain when it wasn't the integrated version).
