Re: Online mode architecture

Hi Chris

The classloading stuff (we call it hook) is already available as a separate
jar (since release 0.8). It is packed in aspectwerkz-core.jar, and requires
bcel.jar and bcel-patch.jar.

For the short story about this, this part was at the beginning an autonomous
project I started on sourceforge. I donated it to Jonas / AspectWerkz when I
joined AspectWerkz.
This part is not documented as a standalone one since the primary goal of
AspectWerkz is not this one. But getting in the source you will see that it
is fairly easy to define your own ClassPreProcessor and even use another
bytecode kit (other than bcel), keeping all low level weaving features
(classloader hierarchy support, offline compilation, native hook, bytecode
kit independance, lightweight).
For further (but out of date and less featured) information, go thru my old
http://besee.sourceforge.net/

Also note that an alternative might be to use JMangler, as AspectWerkz did
before having this  full featured solution of its own (version 0.7.x and
prior).
Also consider that JMangler is GPL / LGPL whereas the AspectWerkz hook part
is BSD licensed.
Depending of your needs, the java 1.4 -Djava.lang.system.classloader  (don't
remember exactly) might also be enough.
