EJB注入为空

Question

I've written an EJB3 business logic and deployed under Glassfish. I'm now going to test it through a client in same container, injecting interface with @EJB.

The problem is that this interface is null

THE CLIENT

public class EjbTest {

@EJB
private static RepAlertManager rep;


    public static void main(String[] args) throws IOException, SQLException {

    try 
    {
        DBConnection.setTypeConnetionLocal(true);

        List<Long> result = rep.doSomething("ENTRATE");

        for(Long temp:result){
            System.out.println(temp);
        }

    } 
    catch (Exception e) 
    {
        e.printStackTrace();
    }
    }
}

THE LOCAL INTERFACE

public interface RepAlertManager {

     public List<Long> doSomething(String message) throws SQLException; }

THE STATELESS bean extending data source

@Stateless public class RepAlertManagerImpl extends DataSource implements RepAlertManager {

public RepAlertManagerImpl() throws IOException {
    super();
}


public List<Long> doSomething(String message) throws SQLException {

        // some code
} }

DATA SOURCE bean is a stateless bean setting connection in the constructor and releasing it through a get() method

This one might help, provided you're using Java EE 6
Testing an EJB with JUnit

Also don't use static when injecting. CDI can't inject a static var.
