JavaEE 6: javax.naming.NameAlreadyBoundException: Use rebind to override

Question

I have a business interface being implemented by two EJBs.

UserManagementService

@Remote
public interface UserManagementService {
    // ...
}

UserManagementServiceJpaImpl

@Stateless(name="userManagementServiceJpaImpl")
public class UserManagementServiceJpaImpl implements UserManagementService {

    @EJB(beanName="userManagementDaoJpaImpl")
    private UserManagementDao userManagementDao;

    // ...
}

UserManagementServiceMockImpl

@Stateless(name="userManagementServiceMockImpl")
public class UserManagementServiceMockImpl implements UserManagementService {   

    @EJB(beanName="userManagementDaoMockImpl")
    private UserManagementDao userManagementDao;

    // ...

}

When I deploy the application to Glassfish 3.1 I get the following error:

java.lang.RuntimeException: Error while binding JNDI name com.transbinary.imdb.service.UserManagementService for EJB : userManagementServiceMockImpl

Could someone help me understand why am I getting this error and how to resolve it?

Answer 1

I got this same exception. In my case I changed my code from
@Stateless(mappedName = "whatever")
to instead be
@Stateless(name = "whatever")
and it solved my issue
