Supposed I got things right, composite persistence units are not what I need.
Neither I want to use extensible entities.
I have entities coded following JPA standards and all I'm looking for is a way
to inform the entitymanager about those entities.
Beside the hack of assembling an xml-file in memory and pass the result to
entitymanagerfactory - is there an "officially supported" way to extend the list
of entities?
Could the names be passed as properties, or what else can I do?
kind regards
Gero
