Hi All,
I�m new to EJB3.0 and JBoss so struggling with all the strartup 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

public interface UserService extends Serializable {
public User findUser(String userName);
public boolean addUser(String userName, String firstName, String lastName);

Session Bean
public class UserServiceImpl implements UserService {

This is the class which gets called from the JSP.
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 className = context.lookup("UserServiceImpl/remote").getClass().getName();
userSvc = (UserService)context.lookup("UserServiceImpl/remote"); //ejb-name
System.out.println("-->> lookup object successfully");



Im getting this exception
java.lang.ClassCastException: $Proxy81

I don�t have any jboss.xml or any other xml files as I suppose that we don�t those with EJB3.0.
Any help would be greatly appreciated
