Hi Hermod, Thanks for your information, but this approach is not what I want, according to http://www.eclipse.org/aspectj/doc/released/devguide/ltw-configuration.html there're 3 ways to enable load-time weaving, your suggestion is #1 agent, but I would like to use #3 Custom classloader (WeavingURLClassLoader).
My application is multi-Classloader application, a sub-component has its own ClassLoader (My App classloader) to load its classes to get working, my intention is to use WeavingURLClassLoader to wrap in My App classloader, so my classes can be weaved at load time. I want to know how and what I need to do to use WeavingURLClassLoader.
