Question

I define a class, and then I instate an object of that class type. I want to send this object to another Java application running on a different computer transparently. What is the best technology to accomplish this?

Answer 1

you can create object streams using the java API and send any serializable object. but you’ll have to mind that these go unencrypted through the network:

on the sender’s side:

CustomObject objectToSend=new CustomObject();
Socket s = new Socket("yourhostname", 1234);
ObjectOutputStream out = new ObjectOutputStream(s.getOutputStream());
out.writeObject(objectToSend);
out.flush();

and on the receiving end:

ServerSocket server = new ServerSocket(1234);
Socket s = server.accept();
ObjectInputStream in = new ObjectInputStream(s.getInputStream());
CustomObject objectReceived = (CustomObject) in.readObject();
