Marcell Barbacena commented on JBSEAM-2994:
-------------------------------------------

Well, maybe we do not need a classloader...
We can attach a proxy of WebRequestCycleProcessor that the resolver method dynamically creates a proxy of the same type returned and that load the triggered method annotations. I do not know if it is possible to create this proxy with CGLib...

Like:

public class ProxyRequestCycleProcessor implements IRequestCycleProcessor {
  private IRequestCycleProcessor proxy;
  public IRequestTarget resolve(RequestCycle requestCycle, RequestParameters requestParameters) {
    IRequestTarget target = proxy.resolve(requestCycle, requestParameters);
    return createSeamProxy(target);
  }
  private IRequestTarget createSeamProxy(IRequestTarget target) {
     // creates a proxy using this cglib method interceptor
     // public Object intercept(Object object, Method method, Object[] args, MethodProxy proxy) throws Throwable {
     //   method.isAnnotationPresent(Begin.class) --> do begin 
     //   other annotations...
     // }
  }
}
