Hi,
Myself Sanjeev Kumar from Lufthansa System. This regarding the support of
EJB3/JPA by TENEO. I am doing some proof of concept(POC) with
TENEO,EJB3/JPA and hibernate. The restriction from my side is that I
cannot annotate the model with OR mapping due to power desinger
limitation. I did the following POCs:
1. I generated the hibernate OR mapping file using power designer, and
configured the teneo to lookup this mapping file instead of generating it
own in memory (by using PersistenceOptions.USE_MAPPING_FILE, as "true"). I
am able to save and retreive domains object using this strategy.
2. In the second test, instead of using the hibernate mapping file, I have
generated the OR mapping file (EJB3/JPA compliance) using power designer.
As mentioned above, I cann't annote the model itself due to tool
limitation. I am exploring the teneo to configure it to use this OR
mapping file. I am not sure wthether this can be possible with TENEO or
not.
Request you to please let me know, does TENEO can be configures to work in
this way.
Thanks & Regards,
Sanjeev

Hi Sanjeev,
There are probably some differences in the mapping. I would generate the same mapping file through
Teneo and then do a comparison. Then if you specific differences post them here (or better in the
EMF newsgroup) and I can give more background info.

Hi Sanjeev,
Correct the xml of Teneo is aimed at offering a possibility to annotate the model not to follow the
orm EJB3/JPA spec. Now I also understand what you mean, I thought that you were generating a
Hibernate hbm file and not an orm file.
So I am afraid that currently the answer to your question is that this is not possible (generate an
orm file and use that as input to Teneo).
