Re: [aspectj-users] Pointcut - NoAspectBoundException

[Andy Clement <andrew.clement@xxxxxxxxx>]

Normally the aspect state (for singleton aspects) is initialized very early - by code inserted into the static initializer for the aspect.  I probably need to see a more complete failing example to comment on what is happening to you. If I try to replicate what you describe, I don't see the NoAspectBound, so I must be doing something a little different to you.  Normally a NoAspectBound could indicate your aspect is advising itself and attempting to run advice before the static initializer has done its job. If you can post a failing sample I'll explain why it is doing what it is doing.

On your second point:

As you haven't specified static or !static, that pointcut should be matching calls to static or non-static methods. If you wanted to limit it to static:

call(static * com.blah.profiler.aspects.HelloWorld(..))

If you wanted just non static

call(!static * com.blah.profiler.aspects.HelloWorld(..))

Hope that helps,

cheers,

Andy

Found the issue to my problem.

The default constructor was calling a method of another class before the aspect was initialized, which caused the exception.

What is the approach to initialize aspect state without hitting this exception?

I'm trying to create a generic pointcut that allows me to have a Before/After hook into method calls.  The point cut I use is:

    @Pointcut("call(* *(..))")
    public void callPointCut() {
    }

However I'm getting the following error when running the test program:

Exception in thread "main" org.aspectj.lang.NoAspectBoundException: Exception while initializing com.blah.profiler.aspects.ProfilerAspects: org.aspectj.lang.NoAspectBoundException: com.blah.profiler.aspects.ProfilerAspects

I'm assuming the following method is causing the grief in HelloWorld.

public static void main(String[] argv)

When I use the fully qualified class name in the pointcut definition I don't get this error, however I don't understand why the problem above is a issue in that case as well.

For example the following point cut:

    @Pointcut("call(* com.blah.profiler.aspects.HelloWorld(..))")
    public void callPointCut() {
    }

Is called for non-static methods i've defined in HelloWorld.  How do I include static methods in the Pointcut definition?
