Creating Jars from NetBeans

[Rob Ross]

Does anyone have any experience creating Jar files from NetBeans?
I'm getting an error when I compile my Jar recipie :

duplicate entry: META-INF/MANIFEST.MF
This prevents the contents of the archive from being updated.

I'm trying to bundle all my compiled .class files, as well as all the .jar files my classes are using, into one jar, with a main class selected so that I can execute by just double-clicking the finished jar file.
I have to admit, I haven't really created jar files a lot, and have never had to make a manifest file, so I don't know if I'm doing something wrong. I do know that all the jars I am including along with my class files each have their own manifest, but that should not be a problem because I can successfully build the same jar from ANT or from JBuilder, and our team also can build it from MetroWorks, so that tells me it's an issue with NetBeans.
Any ideas?
Thanks!

This is because you try to include multiple jar files which all have the MANIFEST.MF entry.. and since netbeans unjars them it tries to put it all into same directory (that is what I think happens) and therefore this message..
well, thats at least what my problem where when I got exactly the above message..
