    A .jar file contains program resources. See the API doc for the jar command for how to create a .jar file.

    A .jar file has the same structure as a .zip file. Any utility that can open and extract files from a zip file can do the same with a jar file.
    If you want to change the contents of a jar file, extract its contents to a folder using a zip utility, update the files in the folder and then use the zip utility to create the jar file with the same structure as it had before this process began.

    I've never worked with secured jar files and there may be restrictions on what can be done to the jar file.

    This thread moved from What's wrong section - There is no OP code with problem here.
