JavaEE 6: javax.naming.NameAlreadyBoundException: Use rebind to override
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
By default GlassFish Server specific default JNDI names are applied automatically for backward compatibility. So com.transbinary.imdb.service.UserManagementService is the the default JNDI name for both the implementations of UserManagementService interface. Which was why I was gettting javax.naming.NameAlreadyBoundException exception.
But because the EJB 3.1 specification defines portable EJB JNDI names, there is less need for GlassFish Server specific JNDI names.
To disable GlassFish Server specific JNDI names for an EJB module, set the value of disable-nonportable-jndi-names element to true. The default is false.
It solved the problem.
