GridResourcesExample.java

This example does the following:

Splits given string into individual words and creates grid jobs for each word.
Every job will save in storage the word passed into it, print it and return the number of letters in that word.

Starting Remote Nodes

To try this example you should start remote grid instances. You can start as many as you like by executing the following script (which simply invokes GridJbossCacheExampleNodeLoader.java): GRIDGAIN_HOME/examples/jbosscache/start-node.bat|sh
Once remote instances are started, you can execute this example from Eclipse, Idea, or NetBeans (or any other IDE) by simply hitting run button. You will witness that all nodes discover each other and will participate in task execution.
