You invoke your container with the AspectJ load-time weaver (LTW),
which plugs into the class loader. There are details in the AJ
documentation. You should google for information about LTW with your
particular container, just in case there are special issues.

Thanks for replying Dean Wampler,
As he said that I have to do load weaving with my EJB container. How
can I
do that?

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!!!
Kindly Regards,
Noppanit Charassinvichai
