Re: [aspectj-users] compilation erros

[Matthew Webster <matthew_webster@xxxxxxxxxx>]

Yusuf,

What are you actually trying to do?
The problem your pointcut is that it is matching _every_ joinpoint in the
control flow of createComponentView()which
I suspect is not what you want. Normally you would target on particular
join point then perhaps restrict the matches to a particular control flow.

Subject	[aspectj-users] compilation erros

Hi,

I am getting compilation errors in the attached file for a very simple aspect. I was wondering if someone could help me decode the errors. Thank you.

This is what the aspect looks like:

package com.tomotherapy.app.ps.components.prescription;

import org.aspectj.lang.annotation.*;

@Aspect

public class TestPrescriptionViewAspect

{

    @Around("cflow(execution(PrescriptionView PrescriptionComponent.createComponentView()))")

    public PrescriptionView aroundCall()

    {

        return (PrescriptionView)new TestPrescriptionView();

    }

}

And this is code that I’m trying to weave:

package com.tomotherapy.app.ps.components.prescription;

import com.tomotherapy.shared.appfrmwrk.component.TomoComponent;

public class PrescriptionComponent extends TomoComponent

    <PrescriptionModel, PrescriptionView, PrescriptionController, IPrescriptionController>

{

    public PrescriptionComponent(){

    }

    protected PrescriptionView createComponentView()

    {

        return new PrescriptionView();

    }

}
