readobject method throws ClassNotFoundException

Question

I\'m trying to pick up Java and wanted to test around with Java\'s client/server to make the client send a simple object of a self defined class(Message) over to the server.

 String s = readClassName();
 Class c = Class.forName(s); // Here your code breaks
 Object o = c.newInstance();
 ...populate o...
