Ok, well perhaps I'm narrowing down, or minimizing the errors.
I seem to be having some kind of conflict with the driver class and possibly
as a result from this, the Context for a connection pool I'd built in the
earlier version. From what I can tell, looking at the TC6 docs, the env lookup
ought to be about the same. I'll double check that, but it looked to be about
just like the way I had it before.
Any way, here's the stack trace error.

----------------------------------
Does it appear the Oracle driver class and tomcat-dbcp jars have classes that
are conflicting?
Thanks, Chuck.

What did you have in mind?
The WEB-INF/web.xml file holds the servlet-spec defined configuration for the
webapp. However, a lot of necessary configuration is left up to the
implementation of the servlet container; Tomcat requires that you supply those
non-spec items primarily in the <Context> element, preferably located as
previously stated.
