I apologize if this question has been previously asked and answered. I have
googled for an answer with no luck.
I have been requested to use OpenJPA on a project. The tool appears straight
forward and works well, I have ran the reverse engineering example on my own DB
- it works great.
I am not sure that it will annotate your exiting code but (I think) it will make
an external mapping file for you or generate the annotated classes from the
ground up. Check out the MappingTool class/docs

That's what I've found too. The reversemapping tool will create new java
files based on the database tables, and provide an orm.xml file. No
annotations though.
You can always add them based on the generated orm.xml file although that
might be easier said than done if you have a lot of entities.
That is correct: the reversemappingtool only currently supports
generating an orm.xml file. We would like to add support for
generating annotations someday, but it is not there yet.
Take a look at the reversemapping example in a recent openjpa
snapshot for an example of running the
Also, FWIW, the BEA Workshop tool (eclipse-based) will
reverse-generate classes from a database as well, and supports putting
the metadata into annotations.

That sounds like the right way to do it. So my container would, on
startup, instantiate OpenJPA's PersistenceProviderImpl, and invoke
createContainerEntityManagerFactory() with a PersistenceUnitInfo that I
implement?
Yes. Note that OpenJPA already has an PUInfo implementation that you

Certainly!
We do have our homegrown solution that does that (along with some other

Hi,
Are you writing this in an EJB, or some other artifact type?

IMO, mailing list is probably good for discussing strategies and
