weblogic上的EJB远程JNDI绑定

Question

I have a simple remote interface:

@Remote
public interface MainDaoEJBRemote {

    void sayHelloRemote();

}

And I have a Stateless EJB that implements my interface:

    @Stateless(mappedName = "MainDaoEJB")
    @Remote
    public class MainDaoEJB implements MainDaoEJBRemote {

        @Override
        public void sayHelloRemote() {

            System.out.println("remote invoked...");

        } 
    }

I have deployed it to a weblogic server.

I have a ManagedBean and I'm trying to lookup for the remote EJB This is my lookup part:

public void sayHello() throws NamingException {
    System.out.println("invoked...");
    Hashtable env = new Hashtable();
    env.put("java.naming.factory.initial",
            "weblogic.jndi.WLInitialContextFactory");
    env.put("java.naming.provider.url", "t3://127.0.0.1:7001");
    env.put("java.naming.security.principal", "user");
    env.put("java.naming.security.credentials", "pass");
    Context ctx = new InitialContext(env);
    try {
        MainDaoEJBRemote mainDaoEJB
                = (MainDaoEJBRemote) ctx.lookup("MainDaoEJB");
        System.out.println("invoked... " + mainDaoEJB.toString());
        mainDaoEJB.sayHelloRemote();

    } catch (NamingException e) {
        System.out.println("NamingException: " + e.getMessage());
    } finally {
        try {
            ctx.close();
        } catch (Exception e) {
             System.out.println("Exception: " + e.getMessage());   
        }
    }

}

When i try to invoked my sayHello() method at the managedBean it throws NamingException : Unable to resolve 'MainDaoEJB'. Resolved ''

Can you tell me how to look up my remote EJB properly? Should I set up the JNDI name of my EJB ?

Answer 1

For remote lookup on WebLogic you should use JNDI name MainDaoEJB#<package>.MainDaoEJBRemote

MainDaoEJBRemote mainDaoEJB
            = (MainDaoEJBRemote) ctx.lookup("MainDaoEJB#<package>.MainDaoEJBRemote")
