The value stored in JNDI is an object - a proxy object that implements the interfaces you define. So...no, you can't pull out an object that only implements one of the interfaces you've defined. However, you should be casting the proxy from JNDI into the interface you want... Interface1 myBean = (Interface1)PortableRemoteObject.narrow( | new InitialContext(props).lookup("address"), | Interface1.class); ...and that way, you'll have compile-time constraints to only invoke operations defined by Interface1. (Code above only for remote lookup; local can skip the "PortableRemoteObject.narrow()) step) S, ALR View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4020840#...
