the name of the vendor is Avantis and the product is called 'Avantis
Unisuite for EJB'. With this tool you model your EJBs in UML (with Rational
Rose for example) and generate the EJBs and the necessary Avantis classes
from the model. But as I mentionend before, it's actually only available in
Germany.
