[jboss-jira] [JBoss JIRA] Commented: (EJBTHREE-1050) Application client support for persistence unit

[Emmanuel Bernard (JIRA)]

Emmanuel Bernard commented on EJBTHREE-1050:
--------------------------------------------

Had a chat with Carlo, here is the proposed solution:
 - enable remote datasource from the application container to the server container
 - deploy the PU locally though Persistence.createEMF

The benefits are:
 - we can also inject DS resources
 - it will work with any JPA implementation
 - can potentially play well with the other client side TX involvements??

Not tunneling the EM API has several benefits as well:
 - network: EM is done to optimize DB calls, not calls to it's API
 - it avoid to keep some sort of stateful remote EM on the server

Drawbacks:
 - second level cache might not play too nicely, we need to keep an eye on it
