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.
Don't get me started about those stupid light bulbs.
