[jboss-user] [JBoss Seam] - AspectJ/Jboss Seam integration ?

[jayzaw]

Hi,

I am using AspectJ for verifying preconditions within a call to a service's business operation method. So, to do this I use around(), which means:

- when entering, the preconditions applying have to be verified by calling the methods. The method names of the preconditions are in a database (cached). They should be called by reflection.

- the problems I have are:
a) for using reflection, I have to be able to reference the class' name. Unfortunately, "this" - within an aspect's advice means a reference to the aspect or the advice. But not the class in which the operation currently executes.

b) the project is a JBoss Seam project. The Jboss Seam component incorporating the service is annotated to be a stateless session bean. So I wonder whether:
b1) AspectJ and Jboss Seam components will have conflicts (Seam uses annotations and maybe other technologies which might conflict with AspectJ)
b2) how to integrate AspectJ in a Jboss Seam project - when trying to create an aspect in my Jboss Seam project, it complains that this is not an AspectJ project
b3) what I should look out for when deploying the project (the aspects should be "weaved" into the code at precompile- or compile-time.

Kind regards,

Jay
