Ever get this?
[WARNING] Enter keystore password: Keystore password is too short - must be at least 6 characters
You probably have something like this:
<dname>cn=Gene De Lisa, ou=Devel, L=Philadelphia, ST=PA, o=Rockhopper, c=US</dname>
See that dname element on line 6? If you reformatted your code in Eclipse perhaps it was split over two lines. It has to be on a single line. So, you problem has nothing to do with the password!
