>From the document: The resources defined in this element are not visible in the per-web-application contexts unless you explicitly link them with <ResourceLink> elements. If you use a GlobalNamingResource element, you will then have to use a <ResourceLink> element in the <Context> element of server.xml. I think you would then use the name attribute specified in the <ResourceLink> element in your /WEB-INF/web.xml <resource-ref> or <resource-ref-env> elements (specifically <res-ref-name> or <resource-env-ref-name>). I'm not at a machine where I can try this, but that's my reading of the documentation.
