    Default .jar help

    So i've wrote many programs in java but never ran them outside the IDE. I have read a lot about creating .jar files. I wrote a simple and famous Hello World Class the just shows a JOption message pane that says Hello World. I use Eclipse with Windows 7. I exported the project in Eclipse to a JAR file. I go to the command line and do java -jar HelloWorld.jar and it runs my program just fine. This is not what I need to do. I want to be able to just double click on it and have it work. ON ANY COMPUTER I PUT IT ON. So I created a batch file that does the Command line stuff for me. I put the .jar file and my .bat file on a flash drive and put it on another computer (Windows 7 also with java 1.6) and I put the .jar file in the same directory my .bat file says it will be and the program DOES NOT RUN! WHY!!! Do I need to include another folder in the same directory as the .jar?? What do I need to do to make an executable thats portable??? And user friendly. People dont want to type CMD lines. Double Click and done. Thanks for the help!

    Do you get any warning messages or anything? And can't your (non-linux) users just double click the jar to run it? Have you looked into webstart at all?

    Make an executable jar by sticking a proper Manifest file into the jar.
    That way the user can double click the jar and it should run.

    That should give you enough buzzwords to Google on.
