Hi All,
I'm new to EJB3.0 and JBoss4.0.3 SP1, so kind of struggling with all the
initial startup problems.
I have a session bean, which I'm testing but I'm not able to get the remote
reference through JNDI lookup.
Heres's my components
@Remote
public interface UserService extends Serializable {
public User findUser(String userName);
public boolean addUser(String userName, String firstName, String lastName);
}
--------------------------------------------------------------------------------------
Session Bean
@Stateless
@Remote(UserService.class)
public class UserServiceImpl implements UserService {
.............
...........
}
--------------------------------------------------------------------------------------
This is the class which gets called from the JSP(using JSF...) and is the
client in this case.
Both EJB and web are running in the same instance of of JBoss
public class AuthenticationDelegate {
public static AuthenticationDelegate authenticationDelegate = null;
private static @EJB UserService userSvc;
.....................
..................
Context context = new InitialContext();
String cName=context.lookup("UserServiceImpl/remote").getClass).getName();
userSvc = (UserService)context.lookup("UserServiceImpl/remote")//default jndi
naming (bean-name/remote )
System.out.println("-->> lookup object successfully");
.............
.............
}
--------------------------------------------------------------------------------------
Im getting this exception when im doing the lookup.

I don't have any jboss.xml or any other configuration xml files as I suppose we
don't need those with EJB3.0.
Any help would be greatly appreciated
Thanks
Ved
