Howdy, I recall having the charAt NPE -- it went away during an upgrade of the JDK (to 1.4.2) and tomcat (to 4.1.27). At that time I also had them update all the Solaris OS patches required by the JDK. So I don't know which was the deciding factor in the charAt NPE you're getting, but doing all the updates should work ;)
