I had the same requirement, I used servlet to do that. If you can use servlet, you can take this reference.

Servlet side

ObjectInputStream objectStream = new ObjectInputStream(request.getInputStream());
User user = (User) objectStream.readObject();
objectStream .close();

Client side

User user = new User();
urlConnectionToTarget.setRequestMethod("POST");
urlConnectionToTarget.setDoOutput(true);
urlConnectionToTarget.setDoInput(true);
urlConnectionToTarget.setRequestProperty("Content-Type", "application/octet-stream");
urlConnectionToTarget.connect();
ObjectOutputStream servletObjectStream = new ObjectOutputStream(urlConnectionToTarget.getOutputStream());
servletObjectStream.writeObject(user);
servletObjectStream.flush();
servletObjectStream.close();

There are two simple ways that I can think of:

  1. Use JAXB to convert the User object into an xml and back to transfer the data between client and server.
  2. Use GSON/Jackson to do the same with a JSON.

Either ways the XML/JSON will directly map to your Objects and are fairly easy to implement.

There are other ways but I assume that you are using a web service and these are best suited for it.

There are many ways:

  1. You can use any of the JSON,XML,SOAP formats.

  2. Or you can use applet

  3. Rmi if using standalone java client.

As mr.icetea suggested you can serialize the java object to json and then pass it . You can do the serialization/deserialization using the jackson library : http://www.mkyong.com/java/how-to-convert-java-object-to-from-json-jackson/
