title: Jar : No Class Def Found Error
body: <p>I am trying to build a project using Ant Build and i have referenced several jars to make it work. Now When i put the jar created by Ant build in some other machine and run it. 
  I am getting the error saying <code>NoClassDefFoundError org/apache... Not found</code>.
  Is there anyway to put all the referenced jars in the classpath of the project or in the manifest file?<br>
  Or is there anyway to repackage all the jar in a project? 
  I know there is one method using <em>jarjar</em> but I don't have any idea of how to use it.<br>
  Please suggest me some ideas, I've been stuck with this small problem for a long time.</p>
