javax.persistence.PersistenceException: Exception [EclipseLink-4021] (Eclipse Persistence Services - 2.5.0.v20130507-3faac2b): org.eclipse.persistence.exceptions.DatabaseException
Exception Description: Unable to acquire a connection from driver [org.apache.derby.jdbc.ClientDriver], user [] and URL [jdbc:derby:localhost:1527/sample;create=true]. Verify that you have set the expected driver class and URL. Check your login, persistence.xml or sessions.xml resource. The jdbc.driver property should be set to a class that is compatible with your database platform

I have taken the liberty of removing a bunch of stuff from your post that has nothing to do with the problem. The salient message is this:

No suitable driver found for jdbc:derby:localhost:1527/sample;create=true

Either you do not have the Derby JDBC driver in the classpath, or the URL is not correct. This page indicates that the latter is indeed the case.
