local class incompatible: stream classdesc serialVersionUID
I know what you people are going to say: this error occurs when you serialize an object and the classes used to serialize/deserialize the object are different versions.
But that is the problem: as far as i know, client/server use the same jar (LITERALLY the same jar, they reside on one machine). But since he gives me two different versions of the same class, i have no idea what is going on.
Is there a way to figure out from which location (which jar) he loads a specific class?
thanks in advance
