Does this answer your question? [No Persistence provider for EntityManager named](https://stackoverflow.com/questions/1158159/no-persistence-provider-for-entitymanager-named) — Prathap Reddy, Aug 08 '20 at 07:10
Error states that the provided `persistence provider` is not valid. Are you sure on the given `persistence provider`? — Prathap Reddy, Aug 08 '20 at 07:15
I was not trying to use Hibernate as its for a teaching purpose of JPA. I found the solution after spending a couple of hr. I added the eclipselink jar which resolved the issue — Lokanath Nayak, Aug 09 '20 at 06:13
