Hello,
The german version of the GlassFish site is kind of outdated. Latest news is the announcement of GlassFish 3.0.1:
https://glassfish.java.net/de/
Are there plans to update this site? If not wouldn't it be better to redirect to the english version? It's still the first hit if you search for glassfish on google in Germany.
best regards
Florian Hirsch
