tomcat datasource definitions - shared vs individual

http://tomcat.apache.org/tomcat-7.0-doc/config/context.html says "Any nested elements, e.g. <Resource> elements, that are defined in a default Context will be created once for each Context to which the default applies. They will not be shared between Context elements."

Default contexts:
$CATALINA_BASE/conf/context.xml
$CATALINA_BASE/conf/[engine]/[host]/context.xml.default

http://tomcat.apache.org/tomcat-7.0-doc/config/globalresources.html#Resource_Definitions describes how to define a database pool that is shared across all Contexts (define the <Resource /> within <GlobalNamingResources /> within $CATALINA_BASE/conf/server.xml).

Is there any way to define a global database pool without touching server.xml?

Thanks!

Figured that was the case, but sometimes you get lucky :)

If such a thing existed, what would be a reasonable location for the <Resource /> definitions?  Perhaps a file $CATALINA_BASE/conf/global.resources.xml?

Don't think so.  Sounds like a reasonable enhancement request (which would have more chance of going in if accompanied by a patch).
