Trying to get JSF up and running to use as a front end to WEASL (coming
soon). Huge problems with missing classes when running the latest JSF
(1.2) in Tomcat 5.0.28, so fallen back to 1.1. Apparently 1.2 requires
a version of JSP that Tomcat doesn't yet support. Trying out the
examples in Core JSF (http://www.horstmann.com/corejsf/)
but got an NPE;

The solution to this is simply to remove the working directory from
under Tomcat and restart the webapp. All will then be well.
