I have the following situation :
Project A - Contains a few entities
and is independent
Project B - Contains a few entities
and is independent
Project C - Contains few entities
and is dependent on Project A & Project B.
I am using Maven to manage dependencies
and builds.
When I try to test Project A
and project B it goes through fine. Each of them has a persistence.xml
and a separate persistent context.
When I run Project C , It does map any of the entities. I have tried to use the auto-detect, specified the jar file attribute ... but nothing seems to work.
It gives me a Mapping Exception saying unknown entity
and wont persist or read the Entities from Projects A or B. I have posted the 3 persistence.xml files here.
Also, I tried using the class attribute
and using the same persistent context but it just wont find the files.
Any help is really appreciated.
Thanks in advance !
