a stateful session bean called 'controller' creates a new object called 'worker'. The worker creates and calls also new objects via reflection. One of these reflected objects should call a method in the controller. That's why I have tranferred a reference of the 'controller' to the reflected objects. When I try to call now methods out of the controller in my reflected objects I'm getting the exception: NoClassDefFound. The class name is the name of the controller and this controller was deployed. Why is this not working?
