JBoss EJB Bean未绑定

Question

I have the following error

 Exception in thread "main" javax.naming.NameNotFoundException: CounterBean not bound

trying to access an EJB JAR CounterBean.jar deployed on JBoss5 from a client application outside the Application Server.

From the Jboss log, it looks like it does not have a global JNDI name? Is this ok? What have I done wrong?

JBoss log:

        s.printCount(i);
        Thread.sleep(1000);
    }
}

This is what I get when I deploy a simple Stateless Session Bean (SLSB) with a remote interface on JBoss 5.x:

    EchoBean/remote-com.stackoverflow.q2440956.samples.services.hello.Echo - EJB3.x Remote Business Interface

When I look at the trace you provided, I can't see anything related to the remote interface (that you'll need for a remote call) and consequently, no JNDI name for it. So the question is: does your SLSB define and implement a remote interface properly?

In my case, my bean is defined like this:

@Stateless
public class EchoBean implements Echo {
    ...
}

And the remote interface looks like:

@Remote
public interface Echo {
    String echo(final String in);
}

Do you have something similar?
