Hi all,

First of all, congratulations for this great piece of work that I am just beginning to fully appreciate.

I tried running a JDBC reverse engineering on our DB model, using Hibernate Tools 3.2beta8 (within Eclipse 3.2.1), with an Oracle 10g db (Oracle9Dialect).

I got a pretty good result, except a nasty error that breaks the start of the HibernateUtil, related to two tables with a join table between them (ManyToMany relationship):

I do understand that I should choose a "side" and not have mappedBy arguments on the two sides, but how can I configure it in the reveng.xml ?
I've browsed the web and forums, but I've not found any way to do it (:-((

Thanks for any help!

current version has a problem with many-to-many and annotations.

workarounds are either disable many-to-many detection
or go in and remove one of the mapped by attributes.

Thank you Max for your insight.

Is there some syntax planned for the reveng.cfg.xml, since I guess it is not obvious to know which one to suppress? Or may be there is some better strategy.

Do you think it will be fixed for the H.Tools CR?

Thanks again,

i will at least make the reverse engineering avoid doing double mapped-by for many-to-many.

Sounds great. Thanks Max!
