Hi Jason,
I think this could be a missing <ResourceParams> in your web application
context in your server.xml. I mean, you need to declare your
<ResourceParams> inside your web <Context> element or inside your
<DefaultContext> element? If not, try do it to because I think that what
is happening is that your web.xml declares a <resource-ref> but there is
no <ResourceParams> available to configure it.
So, the first error (exception) is that it cannot find the
driverClassName because it cannot read the <ResourceParams> (like it was
null).
P.S.- I think this is a Tomcat/DBCP forum question...
Regards,
Pedro Salazar.
