I want to embed libraries to build a single jar file.

also i must notice that im using Netbeans IDE.

Better Solution using ANT:

They both do not answer your question , you need to use Ant . Refer this forums thread for details http://www.coderanch.com/t/419419/vc/there-way-netbeans-include-external

I used One-jar to make easily distributable jar. Not sure if that fits here.
