Thanks I did this and it worked. I then deployed the EJB3 from the JBoss Messaging sample. It deployed, but I can't call it (assume class mismatch since I no longer have Jboss messaging installed). Stupid question ... from the announcement on R9 it says: "The biggest change is that we switch MDB to be fully JCA Inflow based. This means that the JMS RA is required to be used. " Is "JMS RA" the same thing as JBoss Messaging? View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3979474#...
