ResourceLink is the Tomcat's way of doing JNDI, so if you port your app on some other server, the deployer will not even know what is wrong if you do not have that entry in your web.xml, because this is the only thing that gets to be moved around (server.xml is not)
Looks a bit redundant but it is there for protability. I do not see any other reasons for it being there otherwise.
