Put a java project in a jar file

Hi all!
Don't know if I really put that in the right forum, but I hope you will help me anyway...

I have written a Java application, now I want to pack that application into one jar file so that one is able to execute the jar file and run the application but also that one is able to unzip the jar file and gets the source code (within the same directory structure I used while developing).
I tried out different solutions, and I was -of course- able just to zip the whole project directory into an jar file, but that doesn't allow to execute the application. Then I made a self executable jar file (btw using ant) which was "working" as well except that the some thirdparty libs could not be found (but I put them into the jar as well and also in the classpath entry in the manifest).
Does anyone know a good solution for this problem or a good site which explains this issue in detail? (well I was searching for ages now, but if there's a secret place...

)
Thanks ind advance and best regards
Gino

Use utility "jar" to create the jar file from directory tree with
class files.
You need save only class files, not source java files.

Ok thanks!
I found now another acceptable way to provide the sources and the class files in one...

You should see description of jar utility: if you wish create
EXECUTABLE jar, you have build some special 'manifest' of
the jar...
(because jar can contains a lot of classes with main function, what
main should use JVM ? According jar manifest)
