Re: [aspectj-users] Status of using XML config, as opposed to language-based annotations? 
Hi

Let me correct your statement: AspectWerkz is using annotations to
define the aspects, and XML to override the annotation values (thus
you can actually use only xml to define an aspect). AspectJ 1.2 is
using a dedicated language extension. The way you define aspect is not
related to the load time weaving at all.
In AspectJ 5, we will have both annotation style (AspectWerkz like)
and code style (AspectJ 1.2). And we will have xml to control the load
time weaving and refine abstract pointcuts.

The annotation style will indeed be "pure Java" as you wrote though I
am not sure what you mean by "hoping I can add aspects to pointcuts
using pure Java code".

What we will not have in AspectJ 5 that was in AspectWerkz is a way to
define an aspect entirely in XML. The annotation (pure Java 5) will be
mandatory for annotation style, and for prior to Java 5, we are
currently exploring extensions (like our JSR-175 backport
http://backport175.codehaus.org)

You can find more information about that in the AspectJ 5 developer
notebook linked from http://aspectj.org
