java.lang.ClassCastException: $Proxy81

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


@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 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 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

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

Your jndi lookup looks correct. Couple of comments though:

- you don't need @Remote on both the bean interface and the bean class. One or the other.
- you don't need the @EJB annotation in your client class. @EJB annotations are only functional for managed components.
- the bean interface does not need to extemd Serializable

How are you deploying the web and ejb components?

If you are deploying in an ear file, you will need to preface the string in the ctx.lookup with the name of your ear file. Example:

ctx.lookup("earfilename/BeanName/remote");
