Help with Jar file packaging

[hedgracer]

I have developed an application in Java and am trying to package it into a jar file. I have taken the .class file, .java file, .form file and the manifest file and made a file named FileCon.jar. This file, when double-clicked, works on my machine. Unfortunately, when I transport the file to eventual user's machine the file does not work when double-clicked. I have installed JRE 1.3 on the user's machine and tried to run from command line and the program still would not run. Can someone tell me what I am doing wrong? Thanks for all your help in advance.

What error does it spit out at you? Did you develop this program with 1.3.1?
