I use the Admin Console (Sun Admin Server) and pick up the war file. Following
vbkraemer's suggestion above, I was able to get things working by:
1. Deploying my application (choosing the WAR file)
2. modify the persistence.xml to use a different JDBC reference
3. redeploy the application, but selecting the already deploy directory under (domains\domain1\applications\j2ee-modules)
I'd still like to know where the final configurations are stored since it's been suggested that persistence.xml is only used at application deployment and not startup.
