In Ubuntu you have to make the Jar executable in order for it to be launched. Right click, permissions, enable execution. Hope that helps.

And in XP /win7 what we have to do?

You shouldn't have to do anything aside from double click. You have to make sure you have the Java runtime environment installed. Also verify that the the files extension is for sure a JAR. If you followed the directions in the above link it should walk you through the process.

have you followed the instructions here: http://download.oracle.com/javase/tutorial/deployment/jar/run.html (from the above link) - specifically adding the main class definition in the manifest?

After that, the jar can be executed using the following command:

java -jar jar-file-name

some OS will handle this on double click so you dont have to type this every time, but this is not guaranteed on every OS..

The other option is to create a bat/sh file that can be double clicked to launch the jar.

how to create a runnable JAR file of our 'Java Application'.
in eclipse select project->export->java->then select runnable JAR
will this create 'Java Application runnable JAR file...

I'm at a loss to understand what you're looking for. Darryl pointed you to a writeup that contains the answer you're looking for. You seem to have overlooked that, so I pointed out that, yes, indeed, the answer is in there. I thought for sure you would now read it more carefully. Instead, you're repeating essentially the same question a third time; may be you can apply yourself a bit harder?

As to the Eclipse part: what happened when you tried?
