Subject Re: about variable DB schema name support

Quick answer, you can use the openjpa.jdbc.Schema property at EMF creation
time. IIRC this won't work with EMF injection though.

A kludgy way to go would be to not define a schema in p.xml or in the
entities and let it pick up the default schema from your datasource. If you
can use a resource reference in persistence.xml then you can map the
resource reference to different datasources at deploy time.

You'd have to set a custom property on the datasource (or use different
logins) to get different schemas - but it should work.

Otherwise I think there'd have to be some additional hooks in the app
server at deploy time.
