S:\Projekte\aquarium-manager>

if you need the sourcecode, you can checkout http://code.google.com/p/aquarium-manager/
from my point of view i think the error has something to do with the two warnings when the application is startet about the missing manifest
can you please give me some hints how to fix these npe?
