com.sun.proxy.$proxy0 cannot be cast to XXX

I was writing a RMI application. I have a method on the server side, which returns an ArrayList<User> and User is a class I defined myself. The code is like: list = obj.getList(); System.out.println(list.get(0).getName());, and this line generated an exception of "com.sun.proxy.$Proxy0 cannot be cast to User". Can anybody help me about that?

I remember I had this problem before. I added extends Remote at the end of public interface nameOfYourInterface. It worked for me.

If User is an exported remote object, as it seems to be, it appears in the client as the remote interface it implements, not as the implementation class.

So that's what you must cast it to. In this case that means declaring your List as List<UserInterface>, where UserInterface is the name of the remote interface. Adjust to suit.
