EJB3 injection with the logical name

[Siva Masilamani]

Hi

Could somebody please explain me how this things work?

 public class Client {

    @EJB(name="TestSLAnnotationBean")
    private static TestSLAnnotationRemote client;
    //private static StatefulBeanRemote client;

    /**
     * @param args the command line arguments
     */
    public static void main(String[] args) throws Exception {
        // TODO code application logic here
        System.out.println("Output is :" + client.businessMethod());
        InitialContext ic=new InitialContext();
        Object o=ic.lookup("java:comp/env/TestSLAnnotationBean");
        TestSLAnnotationRemote client=(TestSLAnnotationRemote)o;
        System.out.println(client.businessMethod());
    }
}   

In the above code what the ejb annotation says?

Inject the reference to the TestSLAnnotationRemote and then bind the variable to the name TestSLAnnotationBean insteadof com.client.Client/client?

Please let me know if my understanding is correct.

From JEE-API: The name element from javax.ejb.EJB defines "The logical name of the ejb reference within the declaring component's (e.g., java:comp/env) environment."

Thus, in your example, the app client deploy tool creates an entry in the app client's ENC with name "java:comp/env/TestSLAnnotationBean". During runtime the app client container performs dependency injection before it calls the app client's main method (see, for instance, JEE 6 spec, section EE.10.4).
