Allocate exception for servlet enterLet: javax.naming.NameNotFoundException:
ITrmnlAuthenticationBL not bound
@Remote
public interface ITrmnlAuthenticationBL{
}
@Stateless
public class TrmnlAuthenticationBL implements ITrmnlAuthenticationBL{

public class EnterLet extends HttpServlet {
@EJB(mappedName = "ITrmnlAuthenticationBL")
private ITrmnlAuthenticationBL trmnlMg;
