Hello, I am having trouble making JBoss AOP (standalone) use my custom class loader. To keep the example simple, let's say I have a ClassLoader called CustomClassLoader which loads classes from a source other than the class path. Now, assume we have these two classes class A { B someVariable; } class B { A someVariable; } When my CustomClassLoader loads Class A and passes the class's byte[] to transform() OR if I use -javaagent and my CustomClassLoader simply calls defineClass, the AOP library tries to resolve the reference to Class B from within Class A. The problem is that it doesn't use my CustomClassLoader to do this -- it searches the classpath all on its own. I've tried changing the threadContextClassLoader, I've tried registering my classloader with the aspect manager. No matter what I do, the AOP framework uses its own class loader. Any help on forcing the aspecting framework to use my own classloader to resolve references would be greatly appreciated. I am using JBoss AOP 1.5.2.GA with JDK 1.5.
