JSP Expressions do not evaluate!
JSPs that otherwise appear to work do not expand JSP expressions and
instead have include the actual expression in the generated HTML.
This is caused when using JSP2.0 against a 2.5 web.xml. Jasper 2.0
silently fails to evaluate the expression - but most other JSP functions
appear to work.
The solution is to either use a 2.4 web.xml format or upgrade to use
jasper 2.1 (simply running java5 should be sufficient for jetty to automatically select jasper 2.1 if the jars are present).
