The <env-entry>, <resource-ref>, and <ejb-ref> values in the deployment descriptor
are for use when you are running a servlet container inside a J2EE server. Tomcat
doesn't support them when running standalone.
A good way to introduce application-wide initialization parameters, though, is to
use the <context-param> element. Values you enter here can be retrieved from any
servlet or JSP page in the web app like this:
String value = getServletContext().getInitParameter("name");

You would not really want to use system properties for this in the first place.
What would you do if you're running two different web apps in the same servlet
container, and they both needed a property named "abc"?
