Well, I'm at a loss.
After even downloading 6.0.24 with the Windows Installer service and cleaning
up the context.xml and web.xml files in the respective places:
/webapps/META-INF/context.xml
And /webapps/WEB-INF/web.xml
Still, the errors I get:
javax.servlet.ServletException: javax.naming.NameNotFoundException: Name jdbc
is not bound in this Context
org.apache.jasper.runtime.PageContextImpl.doHandlePageException(PageContextImpl.java:862)

My META-INF/context.xml file's contents:
<Context>
<Resource name="jdbc/myoracle"
auth="Container"
type="javax.sql.DataSource"
factory="org.apache.tomcat.dbcp.DataSourceConnectionFactory"
driverClassName="oracle.jdbc.driver.OracleDriver"
maxActive="125"
maxIdle="15"
maxWait="70000"
removeAbandoned="true"
removeAbandonedTimeout="300"
logAbandoned="true"
username="usernm"
password="pwd"
url="jdbc:oracle:thin:@servername100:1526:SID"
minEvictableIdleTimeMillis="5000"
timeBetweenEvictionRunsMillis = "10000"
testWhileIdle="true" />
</Context>
And WEB-INF/web.xml
<resource-ref>
<description>Change Ctrl App</description>
<res-ref-name>jdbc/myoracle</res-ref-name>
<res-ref-type>javax.sql.DataSource</res-ref-type>
<res-auth>Container</res-auth>
</resource-ref>
In addition to the previous servlet mappings that were on there before with
version 4.1.31
How/why would it not find the naming context?
Uuuuuggggghhh!!

I'll totally remove factory. It was necessary in my 4.1 build.
I'll also tweak the other ms time settings, and the WhileIdle - to borrow, like
you suggest and see if that works better, of if at all.
I'll also try removing the resource-ref and see what occurs.
Thanks, Chris.

How about either factory="org.apache.tomcat.dbcp.BasicDataSourceFactory"
or specifying no factory at all and accepting the default (which is that shown
above)?

Right: common/lib, server/lib, and shared/lib are essentially all merged into a
single /lib in Tomcat 6. You can play with catalina.properties and make all
kinds of ClassLoader hierarchies, but it's usually not worth it.

All that looks okay to me, although 700ms isn't a long time to wait for a
connection to come back from the pool: my guess is that you'd rather wait for a
while for a connection and give the user a complete, if late, response rather
than just giving them an error screen.
My position is that testWhildIdle isn't really useful: if you test on borrow,
that's usually sufficient unless you want to basically eliminate the
possibility that a connection will have to be re-established during a user
request.
Finally, 30 seconds is a very short "abandoned timeout", though only you can
determine what is appropriate in your environment. If you have some code which
executes 3 10-second queries, then your connection is considered abandoned :(

In my experience, <resource-ref> is not necessary in web.xml but does follow
the spec.
So, still getting this error, then:
