Persistence.xml - spring JPA?

The anwer consists of two parts. Denisk was correct about the location of persistence. Xml, it should be under src.

I was missing some dependencies to datanucleus (I thought they are provided). After adding them I got plenty of relevant exceptions. After resolving them everything works.So - it was coincidence of two problem, each of them masked part of the other.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
