It's a standard J2EE thing - jdbc/SpringDS is the container-independent 
name you use in your code to provide a layer of indirection, and you map 
it to an actual named container resource (in the JBoss case by supplying 
a jboss-web file). You can do the same in Weblogic:

An explicit lookup would work too but would require code changes every 
time you change to use a different "physical" datasource or if you move 
to a different container.

There's an equivalent syntax for use in EJBs, in the ejb-jar.xml file.
