Hi After a very long development cycle, we have finally introduced CDI and JPA technologies into oVirt. This means that in the next few month you'll see more and more of our stored procedures replaced with JPA code, which will allow us to have easier entity mapping and enjoy performance boost with caching. Some things to keep in mind: 1. When implementing a DAO class, please make sure to annotate it with the @Named and @Singleton annotations. 2. The engine-daos.properties file is no longer needed, and is removed from our code. 3. If you want to migrate your own DAO to work with JPA, please look at the Bookmark, BookmarkDaoDbFacadeImpl and BookmarkDaoTest classes (see patch https://gerrit.ovirt.org/#/c/33836/). There is a simple infrastructure that will allow you to do most of the things you need quite easily. If something is missing - please drop me an email to lzelkha@redhat.com - I'll be happy to assist. Thanks for everyone who took part in this effort - Oved, Moti, Roy, Yevgeny and everyone else.

kudos Liran, the modernization of our code-base is a very important goal. Those aren't just nice toys to play with.

note: this practice is temporary and it should be updated
