May I ask what makes it obligatory for jboss-seam.jar to be declared as an ejb module. I think this was not required before. Any links/documentation on the subject? Here is what I found: http://docs.jboss.com/seam/1.3.0.ALPHA/reference/en/html/tutorial.html vs http://docs.jboss.com/seam/2.0.0.B1/reference/en/html/tutorial.html The jar is declared as an ejb module from B1 onward. Does this have something to do with conforming to the spec and allowing java modules to be moved to /lib? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4086655#...
