If you are using JBoss AS 6 (EJB3.1) you can use the global portable JNDI names, otherwise the old JBoss specific JNDI naming can be used: [ear name]/[simple bean name]/remote.

Since [ear name]/ is removed when you're deploying only an EJB jar, this explains the exception you're getting: SinaBean is a directory (context in JNDI terms), which can contain the actual How to react?

Re: Cannot narrow remote object error? 666705 Jan 3, 2007 1:59 PM (in response to 666705) I am also getting the same issue. The Enterprise JavaBeans 2.0 specification offers an example of resolving a specific session bean home interface:
Context initialContext = new InitialContext();
CartHome cartHome = (CartHome)javax.rmi.PortableRemoteObject.narrow(
initialContext.lookup(“java:comp/env/ejb/cart”), CartHome.class); Is the result of the general election final on 8th of Nov, 2016? Indeed, that's one of the core EJB value propositions.

and/or other countries. How difficult is it to practically detect a forgery in a cryptosystem? You can not post a blank message. It looks like a class-loader issue (the interface implemented by the bean is not the "same" as the interface you are casting to).
