Should I use javax.persistence.jdbc.* properties or openjpa.Connection* properties?
Also, just an observation: after reading the docs, I found that if I omit specifying the "transaction-type" attribute of the "persistence-unit" element, it will automagically pick the correct type depending on whether it's running standalone (JSE) or deployed to a JEE container (in my case, JBoss6). Furthermore, (I could be wrong, but this the behavior I am seeing) - when deployed to the JEE container, the container-provided connection will be identified by the JNDI resource name, specified by the "jta-data-source" element and the "openjpa.Connection*" properties seem to be ignored (thankfully)... yet when running in a standalone JSE app, "jta-data-source" seems to be ignored and the "openjpa.Connection*" properties are in effect. The end result is that I can use the same persistence.xml, without editing, to deploy to either standalone (JSE) or app server (JBoss-6, JEE). This is pretty convenient, I wonder if this is by design? Thanks, Chris
