[jboss-user] [JBoss AOP] - Re: Dynamic AOP and User-Defined Class Loader

[shu_boston]

Hi,

Thank you very much for your help. I tried what you said in the topic you created, and I have bad news and good news :P

Unfortunatelly, it still doens't work with 2.0.0 CR8, but I found it works with 1.5.6. When I override getResource(), my application is sometime required to load "Object.class" and "Throwable.class". Yes, "Object.class" not "java.lang.Object.class". Then, my classloader (getResource()) loads "java.lang.Object.class" by calling super.getResrouce("java/lang/Object.class") instead of loading "Object.class", however, I still got the following exception.

I'm actually fine now since my code works with 1.5.6 thanks to your advice, however I think this is a bug in 2.0.0 CR8. Hope this help you.

Thanks
