I'm no expert but could you show the contents of persistence.xml in your project?
check out whether you create tables or create and drop tables.

Please,make sure that you have given same persistance unit name as you created.

i was facing "Could not resolve a persistence unit corresponding to the persistence-context-ref-name" beacuse i have not given persistence unit name proper.
