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.
