Has anyone used Oracle thin driver to connect. I copied oracle supplied Jar file in common/lib and changed server.xml file to create context. Tried using that context in JSP per example in help pages of Tomcat, I keep getting error invalid driver. I do notice now oracle driver is called jdbc14.jar, believed earlier version was classes12.jar, could that be a problem - though i tried my example with classes12.jar i keep getting same error. Is creating context an alternate way of doing the same thing that we do with import="java.sql", since if I include import statement and do not use context it works.
