[aspectwerkz-user] Custom annotations with jdk5 and ElementType.TYPE?

Thanks Alex,
(what a silly mistake I made) the test now works, however..what I would
really like to be able to do is use a TYPE annotation to bind an aspect to a
class instance. (the same as if I were using an interface to bind aspects).

Config:
 <aspect class="WithinAspect" deployment-model="perInstance">
	<pointcut name="withinInvocation" expression="execution(*
@org.neo.swarm.interceptor.within.InterceptWithin.*(..))"/>
	<advice name="execute" type="around" bind-to="withinInvocation"/>
 </aspect>

Annotation:
 @Retention(RetentionPolicy.RUNTIME)
 @Target(ElementType.TYPE)
 public @interface InterceptWithin {
 }

Applied to this class:
 @InterceptWithin
 public class SomeComponent {
	public String doStuff(){
		return "stuff";
  }
 }

Is this possible or is my config broken again? AW doesn't like to formatting
of the XML and blows up with the error blow 
Many thanks 
Neil.

Hi Neil

Use the full qualified name of the annotation in the pointcut expression (I
guess this one is in some package)
