This week's book giveaway is in the Mac OS forum. We're giving away four copies of a choice of "Take Control of Upgrading to Yosemite" or "Take Control of Automating Your Mac" and have Joe Kissell on-line! See this thread for details.
While going through the JPA Specs (Page 130) , I came across the statement below.
If there is a different persistence context already associated with the JTA transaction, the container throws the EJBException.
If this is the case and I am working with two different Entity Managers pointing to two different Databases , will such operation fail?
Consider a use case in which a session bean method is interacting with two databases (2 phase commit). In this case I would have two EntityManager references. As per the statement above doing so could fail so I am a bit confused about how to achieve this?
Hope I am putting my question correctly as I myself is confused after reading this statement.
Or does the spec say or trying to say - different persistence context but for same database.
