Hi Alan,

Thanks for your interest!

There is a roadmap document (http://objectbridge.sf.net/roadmap.html)
laying out the current status and our future plans.

currently it must be edited manually. But we definitely want to have
such a tool.
I would like to something like the TOPLink mapping workbench, which
provides quite a lot of well structured engineering features.

Sure! OJB relies much on such contributions. We are not sponsored by a
company or any other organisation.
                So everything (even rough code sketches, design ideas,
contructive criticizm if definitely appreciated!

Apart from providing mapping functionality (which allow to map existing
java classes on existing RDBMS tables) we want to have forward- and
reverse engineering features in this workbench :
- from a Java Class model to an xml-repository and to RDBMS tables
- from tables to classes and to an xml-repository.
- from a xml-repository to classes and tables.

There have been several discussions on this topic in the forums.
There is also an outdated entry in the SourceForge TaskManager sketching
my overall idea.

There is also a contrib package on the download page
(contrib-0.7.343.tgz). This archive contains some experimental code
regarding DDL generation.

There is also another SourceForge project (DBGen) that provides
generation of java classes from RDBMS tables.
The code generated won't match for OJB but maybe it's a good point to
start from.

thanks for your offer to help again,
cheers,

Thomas
