Embedded Grid demo

What does the sample do?

This sample demonstrates how to start and use an embedded JPPF driver and node programmatically, in the same JVM as the client.

How do I run it?

From a command prompt, type the following:
  • On a Linux/Unix/MacOS system: ./
  • On a Windows system: run.bat

The demo produces an output put that looks like this, where messages from the demo itself are prefixed with `>>>`:
