The context.xml has global enviroiment variables (like mail server
related vars) that all the dev applications use. All the different
dev applications also use the same database.
So that is why we define resources in the context.xml file
It sounds like you really *do* want to define the JDBC/JNDI resource in
server.xml and the link it to your applications.
I think the correct way to do that is by defining it in server.xml and
then linking it through your applications' WEB-INF/web.xml files.
You should not have to touch CATALINA_BASE/conf/context.xml.
The only reason you might want to touch context.xml is if you want to
provide the same resource link to all web applications rather than have
to specify it in each web application.

You really shouldn't have anything custom in
CATALINA_BASE/conf/context.xml. That will affect every application
deployed on the server. Perhaps you only have a single application
deployed, but things can get really confusing when you edit that file.
It also makes upgrades more difficult.
I would recommend taking your <Resource> from
CATALINA_BASE/conf/context.xml and putting it into the proper place:
your application's META-INF/context.xml file. You will need to
surround it with <Context> ... </Context> since that file defines the
context.
If you have <Context> in your CATALINA_BASE/conf/server.xml file, you
should remove it. If you want to disable auto-deploy, then you can
always copy your application's META-INF/context.xml file into
CATALINA_BASE/conf/[engine]/[host]/[contextpath].xml.
Finally, you should be able to delete your <Resource> from your
CATALINA_BASE/conf/server.xml file entirely.
Do you have anything in your web.xml that is related? For example:
<resource-ref>
<res-ref-name>jdbc/foo</res-ref-name>
<res-type>javax.sql.DataSource</res-type>
<res-auth>Container</res-auth>
</resource-ref>
I have one of those in my web.xml, but it's not clear to be whether or
not I actually need it. I have *one* of them but my application uses
two different JDBC resources. Both are declared in
META-INF/context.xml and both are available to the application.
I think you need to use <resource-ref> in web.xml when you define
"global naming resources" in server.xml. But if you put them into
META-INF/context.xml it's obvious that (a) they aren't global and (b)
the application expects them.
So I would remove any global naming resources you may have in
server.xml and also remove anything you don't need in web.xml.
Doing all this will make upgrading Tomcat much easier.

It's definitely not a requirement to specify it in both places.
I can only log into my app if I have it defined in both my
context.xml and server.xml
Below is my database resource as defined in server.xml..........
I have xxx out postgres URL for security reasons

Which context.xml are you talking about? The one in
CATALINA_BASE/context.xml or the one in your application's
META-INF/context.xml?
Have you defined your <Context> in CATALINA_BASE/conf/server.xml, or
are you using only META-INF/context.xml?
