This is the basic problem with newbies using [IDE wizards|http://forums.sun.com/thread.jspa?messageID=11008689#11008689] to complete tasks - it results in a failure to have any idea what is actually happening 'behind the magic'.
The real answer to this question lies in [manifest files|http://java.sun.com/docs/books/tutorial/deployment/jar/manifestindex.html]. (And it has nothing to do with YourEclipse.)
