Hi Everybody,
I want to know if it is possible to user spring together with teneo. At the moment we use spring and hibernate to create the OR-mappings.
Because of problems with lazy-loading we decided to test Spring + EclipseLink.
Then we noticed that Teneo could generate Hibernate and EclipseLink so if we could use Spring+Teneo this would be a flexible solution because we could generate Hibernate and EclipseLink mappings.
So the question is: Is it possible to use Spring directly with Teneo. I posted a similar question in an other forum. Here somebody referenced to http://www.elver.org/hibernate/hbdatastore.html#spring .
The documentation says, that spring uses HbSessionDataStore/HbEntityDataStore. Does this mean that I can use Spring+Teneo only when I use Hibernate specific DataStores?
Maybe someone who used this feature can help me.
Thanks a lot.

Hi,
I am currently using EMF models in a Spring 3.x MVC application.
The persistence layer is implemented with the help of Teneo and EclipseLink 2.1.
So far I faced some issues, but I was able deal with them:
1. Load time JPA weaving with EclipseLink does not work for EMF models, therefore you should use the java agent supplied by EclipseLInk for JPA enhancements. (I'm running the application inside Tomcat container)
2. Teneo generates an ORM.xml mapping for use with EclipseLink. Depending on the complexity of your model, you could be able to use it as it is generated, or you will have to manually modify it to reflect your model.
Overall I find the use of EMF modeling with Spring based dynamic web applications very cool.
I'm also using EMF models for modeling DAOs and for modeling the services layer, not only for the domain objects model.
