    Heres the deal. I have a jar file with numerous classes in it however I am only using a couple of the classes.

    So I want to create a new jar with just classes I want and thier dependancies.

    Is there an easy already around to do this does anyone know (I can do it myself but would prefer easier way :) )

    Surely you can just unpack the jar and then repack it with only the classes you want?

    Well I what I plan to do is use eclipse to determine the dependancies, but thought there would be an easier way.

    I used this, bit of a pain in the ass to use, but it does find dependencies in the compiled bytecode. It won't build you a cut down jar or anything, so if you already know what the dependencies are then it's of no use.
