EJB 3.0 circular injection problem
Hello,
I using jboss 5.0.0 GA (also tryied on jboss 5.1.0.GA)
I have problem with injection. I have two services:
@Local
public interface DepatureService {
void find();
}
@Stateless
public class DepatureServiceImpl implements DepatureService {
@EJB
EmployeeService employeeService;
@Override
public void find() {
}
}
@Local
public interface EmployeeService {
public void hire();
}
@Stateless
public class EmployeeServiceImpl implements EmployeeService {
@EJB
DepatureService depatureService;
@Override
public void hire() {
}
}
When I remove injection for example in EmployeeServiceImple or inDepartmentServiceImpl then works fine. But when I have this circular injection I get the following exception:
