If you happen to get the above error, it could be that the required Oracle jar might not be in Tomcat lib directory.
In the maven dependencies, I see that Oracle-jdbc-11.2.0.1.0.jar and is exporting to the wtpwebapp's application lib directory.
I fixed the issue by copying the ojdbc6.jar file to tomcat's lib directory.
Hope this helps you.
