Hello everybody
(or should I say Martin Taal Smile

),

we try to use Eclipse Teneo to persist our business models created with Eclipse EMF into a PostgreSQL database and read it from there using the standard JPA EntityMananger API. Unfortunately, the mapping automatically created by Eclipse Teneo does not allow us to use EntityManager.find() method for example as it does not find a valid mapping of our EMF entities.

We created a simple example project attached to this post which can be imported into a default Eclipse Luna Modeling installation/workspace. One just needs to install Eclipse Teneo + Dependencies from [1] and [2], and place the h2 database driver (contained in the attached ZIP) into the dropins folder of eclipse.

We also found an older post [3] which ecountered the similar problem than we do and obviously solved it - just that the solution described there does not work for us.

Do you guys have any idea what is wrong with the setup? In our opinion it can only related to the way we model our entities and/or some Teneo/Hibernate configuration which we are not aware of.

We're glad for any hints not matter if they contain a final solution.

Thanks a lot.

Regards
Timo

I re-created the same topic in the EMF Technology forum as I suppose it fits better there:
