Hi,
Referring to Pro JPA2, it is mentioned in Chapter 2 that persistence unit and entity manager factory have 1:1 correspondance.
But I tried in my application to create more than one EntityManagerFactory using same persistence unit. I used Persistence class to create EntityManagerFactory.

So, how is it one-to-one correspondance?
Please help.

Thanks,
Sudhanshu

I think that is how you would look at it from a logical view, however there is (at least I can't find one) no restriction in the JPA specifications that there should only be one EntityManagerFactory per persistence unit.
