I don't think jar inside jar will work, you may want to extract it out.

yes, one-jar is what you need! :-)
As I know it is plugin for Maven, but I think that you can use it with Ant as well...

It's  Maven 'Shade' you're thinking of. If you're using Eclipse, simply include your jar as a dependent library and its export facility will create a 'fat jar'
