Re: [aspectj-users] aspectJ with EJB problem
Actually, it would print

Hi Toy My Surname
Hi Toy

If you run this code as a normal Java application (replacing the InitialContext stuff with "new MyBean()", for example), it works fine.

First, did you compile the code with ajc? If not, are you using load-time weaving with your EJB container?

I haven't used EJBs in a long time, so I'm not sure how this code is really implemented and managed by the container. However, I suspect that you aren't getting an object of type MyBean, but some proxied object or even a subclass (like they used to do in EJB v2). 

Try adding a plus sign, "+" in your pointcut definition:

pointcut insertSurname() : execution(public String MyBean+.sayHello(..));

This tells AspectJ to match on subclasses too. That might work. If not, perhaps someone else on the list will have the answer.

Good luck,

Dean

Dear, All
 
I was trying to use AspectJ with EJB. My program is very simple, but I have a little problem.
 
This is my Bean which is very simple
 
@Stateless(mappedName="HelloWorld")
public class MyBean implements MyBeanFacade
{
      @Override
      public String sayHello(String name) {
            return "Hi "+name;
      }
 
}
 
And this is my aspect
public aspect TestAOP {
 
      pointcut insertSurname() : execution(public String MyBean.sayHello(..));
     
      after() returning(String name) : insertSurname()
      {
            System.out.println(name +" My Surname");
      }
}
 
 
 
And this is my client tester
 
      public static void main(String[] args) throws Exception {
            // TODO Auto-generated method stub
            InitialContext context = new InitialContext();
            MyBeanFacade bean = (MyBeanFacade)context.lookup("HelloWorld");
            System.out.println(bean.sayHello("Toy"));
      }
 
And I packed these classes together and deployed to Glassfish, but when I invoked the bean. It did show “My Surname”. It just showed “Hi Toy” on my Console. I think it suppose to show “Hi Toy My Surname”. Something like this. Please help me!!!
