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:

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