I am wondering how to use serielizable object. My question is this:
Since the server side don't know anything about the serializable object that received from a remote client, how can I use the methods in this object at server side?
I wrote some code, the server read a object from client, and use the object like this:
object.getInfo() , the compiler complained can't resolve symbol :getInfo(); then I tried to write a interface include this method at server side, and the same interface at the client side, but it still can't work.(of course it is a bad code )
Need your kindly help, thx
