It's not tricky at all if you setup the correct type of NetBeans 
project, as I already said. NetBeans will do it all for you. There's no 
need to start messing with jar's, manifests or Ant. It's very often 
easier to re-create the project as a Java Application than it is to 
"fix" a broken one.

With a NetBeans Java application all you need is the contents of the 
dist/ directory. The main project jar will have a properly constructed 
manifest to allow the jar to be executed with "java -jar project.jar". 
Dependency jar's will be in the dist/lib directory, and a Class-Path: 
entry in the manifest will include that directory. When you build the 
project NetBeans very helpfully tells you exactly how to run it:

"To run this application from the command line without Ant, try:
java -jar "/path/to/project/dist/project.jar".

All you need to distribute to anyone else is the dist/ directory. 
There's even a clue in the name.
