have a look at my posts tagged with aspectj and e.g. this post.

Wasn’t the sample code working for you? Why not? Probably I can help you to get it running.

have a look at the weaving process of AspectJ here or here. Although a little bit more abstract, this article might be interesting too.

Basically, a framework like AspectJ reads your aspects, locates the positions in the code where these aspects should be executed and weaves the additional code into your existing code. In the example of your aspect with some logging statements the code gets weaved into the class with your business logic. This way the resulting class file contains both: the code from your aspect and the code from your class with business logic. So, your class with business logic will not call your class with some logging at all - the code will just be executed at the positions (join points) specified in your aspects.

By the way: if you wouldn’t weave your aspects into your existing code, the code defined in your aspects will not be executed. This is an ideal way to strip away debug logging statements from your program for a production environment. You would just have to turn off the aspects and that would be it.

Hope that helps…
