a) It was a runtime error. I got an exception saying that It couldn't find the persistent unit when I called Persistence.createEntityManagerFactory.
b) Release Candidate 8
c) I call Persistence.createEntityManagerFactory("persistent unit name", props)
d) Updates will be done by one application. All the others will be reading data. Hence, I just want one library instead of having multiple copies so that I can avoid version incompatibility issues.
