Re: [hibernate-dev] [OGM] Transactions in Neo4j datastore
Do you have an alternative in mind?
My understanding is that if you write a Neo4J JtaPlatform, then the
transaction will be started:
- if the transaction is manually started by the wrapping code
- if someone uses Session.beginTransaction() or
EntityManager.getTransaction().begin()
You wanted the Neo4J transaction to be started if @Transactional is
added to a CDI bean? I'd say that's the job of the Neo4J team to amke
sure that one works, no?
If we can find a better solution that would be nice but I'm not sure I
understand the problem :)

Hi,
I'm working at the integration between OGM and Neo4j.
Neo4j is fully transactional and it requires to open a transaction
before the execution of any operation on the DB.
To integrate this mechanism with OGM I've created the class
Neo4jJtaPlatform.java[1] that extends AbstractJtaPlatform and it's
registered using the configuration parameter
hibernate.transaction.jta.platform
If I'm correct, while this solution is working, it requires the
application to manage transactions using the Neo4j transaction
manager. Are there alternatives to this approach?
