In JBoss 4.0.5.GA, it seemed that using the same Java interface class for both local and remote EJB business interfaces worked for most configurations; I can't say what the behavior in 4.0.4 is, but I wouldn't be surprised if it was similar to that for 4.0.5.GA. Here is a related jira issue, which indicates the behavior was fixed for JBoss 4.2.x: http://jira.jboss.com/jira/browse/EJBTHREE-751 View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4081306#...
