I think you are asking for trouble going the multi-EAR route, but you can certainly resolve the JNDI issue trivially by giving your EJB3 components specific JNDI names using org.jboss.annotation.ejb.LocalBinding. | @Statefule | @LocalBinding(jndiBinding="myApp/FooBean") | @Name("foo") | public class FooBean ... | then your jndi pattern would be myApp/#{ejbName} View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3996474#...
