Resource Definitions in context file for JNDI lookup

I have a query related to the contents of element in context.xml file for Jndi look up and the resource-ref element in web.xml . The Tomcat 5.5 reference gives an overview of the Resource element.

  1. As per the reference above , the valid attributes for Resource element are auth,description,name,scope,type but we do include driverClassName , url, username, password etc and a same is in the sample in the Tomcat docs. So is the explanation in the former link wrong?

  2. The reference states that the inclusion of the <Resource> element in context.xml file is equivalent to the resource-ref element in web.xml . If so , can we give the driverClassName , url, username, password and the remaining attributes in web.xml and give the context.xml file a miss ? I don't think we can . So why is the reference so confusing?

  1. Yes, it looks like the first reference is not comprehensive on all the attributes of the Resource element, the second one is much more comprehensive.

  2. It is stated a little wrongly - instead of saying that the resource is equivalent to the resource-ref element in web.xml it should have said that the resource-ref in web.xml maps to the resource element in context.xml. It is a way to provide a local reference with its own name for the resource within a web application, and then during deployment time to map this internal resource name to a real container specific jndi resource - What is resource-ref in web.xml used for?
