Re: [aspectj-users] How to apply advice to an interface in a jar?

Thanks a lot. Using call instead of execution works.

Hi Benyi,
you are trying to weave the JRE classes, which is quite tricky cause you have to weave the rt.jar at compie time and then run using the java bootclasspath option to use the weaved rt.jar. If you want to trace calls to lists only from inside your code, then try @Before("call(* java.util.List.*(..))") .

How can add an advice to the methods of java.util.List?

I include the following into weaver options in aop.xml

<aspectj>

<aspects>

<aspect name="TestInterfaceAspect" />

</aspects>

<weaver options="-verbose -showWeaveInfo">

<include within="java.util.*"/>

</weaver>

</aspectj>

And

@Aspect

public class TestInterfaceAspect {

@Before("execution(* java.util.List.*(..))")

public void beforeListOperations(JoinPoint jp) {

System.out.println("Call " + jp.getSignature().toShortString());

}

}

but I always get a warning "advice defined in TestInterfaceAspect has not been applied [Xlint:adviceDidNotMatch]"?

I'm using Eclipse 3.5 with AJDT.
