[java] Cannot create JDBC driver of class ' ' for connect URL 'null' : I do not understand this exception

I had a similar problem using Tomcat against Oracle. I DID have the context.xml in the META-INF directory, on the disc. This file was not showing in the eclipse project though. A simple hit on the F5 refresh and the context.xml file appeared and eclipse published it. Everything worked past that. Hope this helps someone.

Try hitting F5 in eclipse
