NodeTray

Node Tray demo

What does the sample do?

This sample provides a node health monitor that sits in the system tray.
It displays the following information:

• A "computer" icon in the system tray, which turns green when the node is connected to a server, and red when it is disconnected
• System tray notifications when the node status changes
• Information about the node's performance and connection to a JPPF server, when the mouse is hovering over the icon

Here are some screenshots:

How do I run it?

Before running this sample application, you need to install a JPPF server and at least one node.
For information on how to set up a node and server, please refer to the JPPF documentation.
Once you have installed a server and node, perform the following steps:

1. open a command prompt in JPPF-x.y-samples-pack/NodeTray
2. important: to build this sample you need a JDK 1.6 or later, as the system tray APIs are not available in prior Java versions
3. build the sample: type "ant jar" or simply "ant"; this will create a file named NodeTray.jar
4. copy NodeTray.jar in the "lib" folder of the JPPF node installation, to add it to the node's classpath. This is enough to deploy the add-on.
5. start the server and node
6. you should see the new system tray icon

What features of JPPF are demonstrated?

• JPPF node life cycle notifications
• Subscribing to task-level JMX notifications

I have additional questions and comments, where can I go?
