Wrap Stub with dynamic proxy?

Question

Hi All,
I am looking for the answer of this question from couple of days.
I want to create an Interceptor chains on RMI level for an EJB client communicating with an Application server.
This client can communicate using RMI/JRMP or RMI/IIOP, nevertheless the semantics is RMI.
I want to wrap the stub on client side (Maybe static stub already placed on classpath / dynamic downloaded stub) with dynamic proxy and
want to apply some interceptors on it before actual invocation of method.
Is there anyway to wrap stubs with dynamic proxy in any existing client(with no source code only binary form)?

But you're not doing that. You are casting String to Comparable.Why do you think so?
System.out.print("Proxy is instance of Comparable? ");
System.out.println(Proxy.newProxyInstance(Comparable.class.getClassLoader(), new Class[] { Comparable.class },new Proxer(new String("String1"))) instanceof Comparable);
System.out.print("Proxy is instance of String? ");
System.out.println(Proxy.newProxyInstance(Comparable.class.getClassLoader(), new Class[] { Comparable.class },new Proxer(new String("String1"))) instanceof String);
System.out.print("Proxy is instance of Object? ");
System.out.println(Proxy.newProxyInstance(Comparable.class.getClassLoader(), new Class[] { Comparable.class },new Proxer(new String("String1"))) instanceof Object);
Output:
Proxy is instance of Comparable? true
Proxy is instance of String? false
Proxy is instance of Object? true
