Error while running the "Using JSPs" example in the Google App Engine Getting Started guide for Java

I was going through the Google App Engine Getting Started guide for Java.  When I got to the "Using JSPs" portion, after deploying the JSP example, I got this error:

HTTP ERROR 500 

Problem accessing /. Reason:The absolute uri: http://www.oracle.com/technetwork/java/javaee/jsp/index.html cannot be resolved in either web.xml or the jar files deployed with this application

It couldn't find the tag library declaration "http://www.oracle.com/technetwork/java/javaee/jsp/index.html".  I changed it to the usual "http://java.sun.com/jsp/jstl/functions" and the example ran fine.

Hope this prevents anyone from getting stuck while doing this tutorial.
