How to share object between java applications?

Question

I have 2 separate Java Applications running at a time. (Two separate javaw.exe) I need to share an object between them while they are running.

What is the simplest

Answer 1

You can use TCP

1. Use a local software port, say localhost:999.
2. Make one application as server (listening on this port) and other as client (will connect to server at localhost:999, but will use different port for it's own use).
3. Client will serialize your object to stream.
4. Server does de-serialize!
