I am working on fixing the bugs in a pre written java/swing application. Now that all bugs are gone I create a jar of the application to distribute it and the jar doesn't run. 

Both classpath file looks the same, the one in eclipse with the one in jar. No luck :(
I hardcoded the path to all .jar files in the manifest file, Still didn't work !

Is there anything else I should be checking as well ? Any help is greatly appreciated. I hate to resort to the last solution of making the testers run the app from eclipse. 
Let me know if If any of the files/code you want me to post here. 

Thanks in advance.
