problem with output of jar file

[nishant.4545]

Hello everyone
I have written a simple program that displays Hello. Then I have created its jar file using the following command:

jar -efc Hello Hello.jar Hello.class

The jar file runs well in the command prompt by using the following command:

java -jar Hello.jar

But when I double click the jar file, nothing happens. No output is displayed. How can I make the jar file run simply by double clicking it?

Your system must be configured to execute jar files like this. If on Windows, a file association is required. Try reinstalling Java and it should be set up automatically.

If this is just a console application, it is likely that the command window appears and disappears before you can see it, as the program is so short.
