    Default Re: How to run Java Program with including external jar

    When i tried to run this program from command prompt,
    Can you post the full contents of the commandline you entered?

    If you are using the -jar option, does the jar file contain a proper manifest file?
    Are the required class files present in the jar file?
    If you don't understand my answer, don't ignore it, ask a question.
