Class not found error while creating Derby Context Aware Function with ClientDataSource driver

Question

I am using derby as datasource in weblogic with org.apache.derby.jdbc.ClientDataSource driver. I have started derby database with ${WL_HOME}/common/derby/bin/startNetworkServer.sh

Datasource is getting created properly but while fetching connection and creating context aware function it throws class not found error.

Caused by: java.sql.SQLSyntaxErrorException: The class 'test.vti.VTITest' does not exist or is inaccessible. This can happen if the class is not public.

How to include test.vti.VTITest in classpath so that ClientDataSource driver can find it?
