Tool to pseudotranslate Java resource bundles

HI all, 
does anybody know of a tool or a way to do a pseudotranslation or a
dummy translation (e.g.: German) of Java resource bundles. I need this
for i18n testing purposes.
The tool JILKIT offers this but the only dictionary available is
simplified Chinese. I would like to have a European language like
German. I would need to upload a dictionary and I haven't been able to
find one for German.
Any help will be greatly appreciated!
Thanks in advance, 
Gladys
