Hi MATHUS,
I do not agree with you a litter.
The EJB Specification only sayes that if you plan to use EJB DI,
you must use @EJB Annotation.
However, Zhao'output displayes that using @Resource can find a SLSB,
At the same time, a ClassNotFoundException is throwed. So, I think that
the output including exception is not accepted by Zhao(including me).
Other ideas?
Best Regard!

Subject: Re: Problem with @Resource
Err, if your HelloWorldRemote attribute is a SLSB, why don't you use @EJB?
Cheers

Hi everybody.
I have a very intersting problem.
I used @Resource to inject a SLSB in ACC,like this:
===============================================================
public class Main {
@Resource(mappedName="hello")
static HelloWorldRemote helloWorld;//SLSB
@Resource(name="hello")
static String hello;
public static void main(String[] args) {
System.out.println(helloWorld.hello());
System.out.println(hello);
}
}
=============================================================
When I run the ACC, I get the right result but with some
Exception,like this:

As I know ,_at_Resource can't be used to inject SLSB.
The behavior of GlassFish V2 is correct?
Any idea ?
Thank you...
