    Packaging a files to JAR?

    How do I package all my files to a single jar file? I have libraries that
    are jar files themselves.

    My file:
    prog.class

    Includes:
    demo.jar

    I have tried: "jar cvm myNewJarFile.jar prog.class demo.jar" , but that
    didn't work when I tried to run my program.

    I don't know why you need to do that, but if you want to then you do this:

    1. Take all the files out of demo.jar and put them into a directory
    somewhere.

    2. Put prog.class and all files in that new directory into the new jar
    file.

    Christer,

    You almost had it right. You want to use "jar cf myNewJarFile.jar prog.class
    demo.jar". The "f" flag is so you can specify the jar filename.

    I found that the jar file within the jar file could not be used in the classpath
    though. What you might want to do is to extract the jar archive with "jar
    xf jarfile.jar" and put the class files into your jarfile.

    I hope that this helps you out.

    Greg
