I set up Jasper2 on Tomcat 4.0.3 as previously recomended. Our webapp worked great.
But other webapps, inclding the JSP examples don't work. Wehen invoking a jsp such as
this: http://host:8080/examples/jsp/dates/date.jsp this exception is displayed:
javax.servlet.ServletException: Servlet.init() for servlet jsp threw exception

I'm off to run our stress test script to see if the memory leak shows up (or not).
I'll keep you all posted.
