Is it possible to serialize anonymous class without outer class?

Question

I made a small research on web and reviewed related topics on this site, but the answers were contradictory: some people said it is not possible, others said it is possible, but

Answer 1

Your example as stated above cannot work in Java because the anonymous inner class is declared within class Caller, and you explicitly stated that class Caller in not available on the RPC server (if I understood that correctly). Note that with Java RPC, only data is sent over the network, the classes must already be available on the client and the server. It that respect your example doesn't make sense because it looks like you want to send code instead of data. Typically you would have your serializable classes in a JAR that is available to the server and the client, and each serializable class should have a unique serialVersionUID.
