Java Development Tools

Hi Guys,

I just wondered wheter there is a fat jar for Jdeveloper.
Let me explain:
I am building stand alone jar file and I want to include other jar files,
I heard about an option in eclipse which get this done: fat jar,
not quite sure how it works but the jars are included in a fat jar and when a class not found exception occurs, the classloader is looking inside the jars in the fat jar. then loads the class. This way you can include jars within a fat jar.
Is this also an option within Jdeveloper?
Here is the fat jar link:
