Java serialization over network

Question

Just want to know if there's a tutorial or a how-to for serializing objects, putting them into a stream over network, and deserialize it on the other side. I understand the principles of serialization, I/O, streams, sockets, and so on, I just would like an example of a client sending an object to a server to start with.

Answer 1

This (pdf) is a useful tutorial which walks you through the basics of serialisation, and sockets, then ties the two concepts together (about halfway through the slides) to show how to serialise an object and send it from client to server (no RMI). I think that's precisely what you want.

Answer 2

Its pretty simple, actually. Just make your objects serializable, and create an ObjectOutputStream and ObjectInputStream that are connected to whatever underlying stream you have, say FileInputStream, etc. Then just write() whatever object you want to the stream and read it on the other side.

Heres an example for you.
