Hi Guys, I have the following scenario: I've a database schema per user in my application(an online ERP/CRM). All the schemas have the same tables, I would like to know how to map it in my persistence.xml file. If I need to specify a jta-data-source I'm hardcoding the client for that persistence unit. Do I need to create a persistence-unit per client and map all the classes in all of my persistence-units ?
