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.

Can someone tell me why I need to have my database source defined in

it in only one location?
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
<GlobalNamingResources>
<Resource name="jdbc/app-pool" auth="Container"
type="javax.sql.DataSource"
driverClassName="org.postgresql.Driver"
url="jdbc:postgresql://xxxxxxxxxxx"
username="postgres"
password="postgres4now"
maxTotal="30" maxIdle="30"
maxWaitMillis="-1"
removeAbandonedOnBorrow="true"
removeAbandonedTimeout="90"
testOnBorrow="true" validationQuery="select 1"
validationQueryTimeout="30000"
testWhileIdle="true"
timeBetweenEvictionRunsMillis="60000"
testOnReturn="true"
/>
</GlobalNamingResources>
Below is my database resource as defined in context.xml
<Context >
<Resources allowLinking="true" />
<Resource name="jdbc/app-pool" auth="Container"
type="javax.sql.DataSource"

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?
