// This is the class that overrides the GenericPortlet class methods
// You can create your own portlet just customizing the code skeleton
// available below. It provides mainly a working example on:
//    1) How to manage combination of Actions/Views
//    2) How to manage portlet preferences and help
//    3) How to show information using the Log object
//    4) How to execute a distributed application with GridEngine
