Hi,
I want to weave interceptors which loaded by a user-defined class loader (like NetworkClassLoader), but I got a javassist.NotFoundException. My code is as follows
ClassLoader loader = new ... // my class loader
Thread.currentThread().setContextClassLoader(loader);
Class clazz = Class.forName("aspect.GreetingInterceptor", false, loader);
AdviceBinding binding = new AdviceBinding();
binding.setPointcutExpression("execution(* *.Test->*(..))");
binding.addInterceptor(clazz);
AspectManager.instance().addBinding(binding);
Test t = new Test();
t.print();
My class loader reads aspect.GreetingInterceptor.class file and calls defineClass() to load it. At the end of the code above, aspect.GreetingInterceptor is supposed to be invoked. When aspect.GreetingInterceptor is in classpath and specified as addInterceptor(aspect.GreetingInterceptor.class), it works fine. However, I got following exception when aspect.GreetingInterceptor is loaded dynamically.
Exception generating JoinPoint_print4216308509294254048_1: aspect.GreetingInterceptor
java.lang.RuntimeException: Error generating joinpoint class for joinpoint Method[method=public void Test.print()]

Does anyone know how I can use dynamically loaded class as an interceptor?
