Is it possible to persist hybrid model using Teneo? [message #487842]

For example, A normal Java Class is defined as below:

Public class MyStore{
Book book;
}

Assume that Book is an EMF class, which is referenced by the JavaBean
class MyStore, how to save them all by Teneo?

Thanks a lot!

Hi David,
This should work but you have to extend the HbSessionDataStore/HbEntityDataStore class, override the mapModel method and
add your own classes/mapping files to the configuration. Something like this:
protected void mapModel() {
super.mapModel();

// and then add your own classes/mapping by getting the Configuration object
// by calling getHibernateConfiguration/getConfiguration

}

Btw, I think this is an interesting case to support so feel free to post any obstacles you encounter, then I can solve them.

Are you using hibernate annotations or hbm.xml for your non-EMF classes?

Last thing, support for Teneo is given on the main emf newsgroup which I added as cc.

Marten, so thanks for your reply! In general, I use hbm.xml as mapping
configuration, but I think that using hibernate annotations is more
suitable if the non-EMF classes is generated by Tool/Compiler.

What are the differences between annotations and *.hbm.xml files in Teneo?

Regards!

Hi David,
Teneo works with JPA annotations in the model and not in the generated code. Internally Teneo translates the annotations
to a hbm which is passed on to Hibernate.

I am not sure if you want to combine non-EMF code (with JPA code) with EMF code which uses Teneo. If so: the key is that
for Teneo/EMF you have to use the HbSessionDataStore/HbEntityDataStore which means that you have to use the
SessionFactory/EntityManagerFactory created by these classes. I think that you can add the JPA annotated classes to the
Configuration object (see the getConfiguration() methods in the DataStore classes). So then you can use one
EntityManager for both Teneo and the non-EMF classes.
