Re: [aspectwerkz-user] A couple of questions

Here is a note for what I mean on AspectJ 5 feature completion. I am
assuming that as AW user what you want is
- offline compilation
- online / load time weaving mode
- aop.xml files for load time weaving, not required to run with Java 5
- aspects in plain java files, not required to run with Java 5

Right now AspectJ 5 M4 as all that except:
- be able to define pointcut in XML (instead of aspect class)
- mixin support

So I mean that we are just close to finish all that. We will then do a
RC1 with that things that -if you want - you should definitely try
before we ship the final version. I hope to see RC1 within a month and
final before christmas - as we intended to achieve.

So the last step in this process is to evangelize what we have done ie
clearly write from an AW user perspective what that means and what to
do / where to start / what to concentrate on.
So far there is only raw documentation about what AspectJ 5 is, how
load time weaving is configured and such - available on aspectj.org
"AspectJ 5 developer book". A good starting point but not really hands
on.
