I am working on a new MDB and I decided to use EJB3. I downloaded JBoss 4.2.1 (which seems to have EJB3 build in) I can't seem being able to find jars to compile my code. In particular I am having an issues with @ActivationConfigProperty annotation. I've tried to add all jars files that I could find with the jboss instalation, but that did not help. Does JBoss has definition for this class or maybe I need to get it somewhere else? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4091250#...
