You should check the @this, @target and @args for accessing the annotation. Than getting the value
is just normal annotation usage.
In the case your pointcuts are not defined in terms of annotation, than you can use the reflection
API to get to the annotations.
Ok,
does this mean, that I can access annotation values only when I define my aspects as annotations too? Can you provide some example how to do this?

Considering that you need those values at runtime, and according to the specification of retention
policies, I would say that no, you are required to use the RUNTIME retention.

You can check the AJ5 Developer's Notebook at
http://www.eclipse.org/aspectj/doc/released/adk15notebook/index.html and mainly for the above
question the Annotation chapter.
