在Weblogic中通过注释查找

Question

I am using EJB3.0, Weblogic 11g

I am trying to do simple lookup from servlet to Statelessbean and run there a method. both under the same EAR. I managed to do it with Jboss. but I know that in Weblogic it's little bit diffrent so I channged my code and this is what I am doing and still no success:

The interface I have declared:

 @Local
 public interface OperatorBlockBeanLocal
 {
    public void testme();

 }

This is the class which implements the Interface:

@Stateless
@Local{ OperatorBlockBeanLocal.class })


@JNDIName(value = "OperatorBlockBean")


 public class OperatorBlockBean implements OperatorBlockBeanLocal
 {
    public void testme()
 {
    System.out.println("OperatorBlockBean");
 }
 }

And this is the servlet which trying to lookup the bean I decalred before:

try
    {
        context = new InitialContext();

        operatorBlockBean = (OperatorBlockBeanLocal) context
                .lookup("java:comp/env/OperatorBlockBean");
        operatorBlockBean.testme();
    } catch (NamingException e)
    {
        // TODO Auto-generated catch block
        e.printStackTrace();
    }

Ofcourse that I get NamingException. anyone has any idea?

thanks, ray.

Try using

@Stateless(mappedName="OperatorBlockBean")
@Local{ OperatorBlockBeanLocal.class }
public class OperatorBlockBean implements OperatorBlockBeanLocal

You can also use EJB injection in your servlet and not do a lookup. Here's how:

@EJB OperatorBlockBeanLocal operatorBlockBean;

The EJB will injected so you don't have to do a lookup.
