Welcome to the wonderful world of O/R mapping :-)

I'm working in a large IT-Company as a consultant in a J2EE prototyping
project. (We have to build a working ground architecture for other projects
that will build real world solutions). As one of the most important tasks we
have identified the Persistence issue. We will do an indepth study of all kind
of commercial products (Avantis Unisuite, CoCobase Versant VEC, Persistence
Powertier, Toplink, IBM VAP). Of course we will also have a look at
ObJectBridge. Using the already running PersistenceBroker with Bean Managed
Persistence entity beans should be quite straightforward.
I'm really interested in seeing the results of performance benchmarks.
I think ObjectBridge will be pretty slow and not very reliable compared to
commercial product running for years.
But OTO its not as difficult to use as all these monster products.

All people who have some experience with such tools tell me that they are
quite a burden in your development cycle and that some/most of them do not
work well.

Agreed. Unfortunately I have no experience with CVS, so I'm looking for a
volunteer to get it running

Sorry, I will have to place it at some more prominent place in the README.html
!

Done !

I set up a developer mailing list:
http://lists.sourceforge.net/mailman/listinfo/objectbridge-developers
please subscribe this list, so that we all can share the content of individual
discussions.

best regards, beste Güße,

Thomas
