Unable to run jar file without lib folder containing swing-layout-1.0.jar

Question

I have done my project through NetBeans 5.0. Eventhough I have copied my lib foloder containing swing-layout-1.0.jar inside my project.jar, I am still unable to run my project.jar in other systems, it is creating an error as Could not find the main class. Program will exit. But if I copy the lib foloder containing swing-layout-1.0.jar in the same path as the project.jar, then my project.jar is running.
But I want to give only the project.jar for other users and not also lib foloder containing swing-layout-1.0.jar each time.
Could someone please help me with this.

When you develop GUI applications using the Netbeans you may endup using netbeans specific jar files in your auto generated code.
And when you build jar files with netbeans it copy the third party jar files used in a application in to a lib folder in the same directory as the jar file of your project. And then set a class path entry to those jar files in your project jar file's manifest file.
So if you want to redistribute the package you have to redistribute your jar file and every thing in the lib folder in with the same directory structure.
If you want to change the structure you will have to change the class path to suit the new structure.
