[hibernate-dev] Hibernate as JPA persistence-provider in SAP Netweaver

[De Silva Jayasinghe, Robin]

Hi Steve!

I accept the fact that the connection obtained by SessionFactory is in no relation to the one used by the Session. However, Table 2 in chapter 4.5.2 of "EJB 3.0 Core Contracts and Requirements" states that during dependency injection in a SLSB the access to ResourceManager is not allowed. We interpret this part of the spec in a way that a SLSB is not allowed to access to any resources (including datasources). Of course we accept the fact that you might interpret the spec in a different way. I only want to raise some awareness that Hibernate in its current state does not run as smooth as it could on Netweaver. 

Best Regards,
Robin
