The most straight forward way is to create an RMI method call.

It's built into java from the beginning, reasonably simple and lightweight.

The two programs run in separate processes. You will need to create an interface between the processes (or as Matthew put it: implement inter-process communication). There are millions of ways to achieve this, just to name a few:

  • Create a file-based interface (Test will write into a file and JLabel will read that file)
  • Create a TCP/IP connection between the two
  • Create a HTTP connection between the two (JLabel may run a glassfish thread or something like that)
  • Create a JMS connection
  • Create an RMI method call
  • Create a Webservice (again with JLabel running glassfish)
  • Many more...
