Hi Eric, It actually looks like what you've done is correct. Make sure that you've recomppiled the org.apache.taglibs.standard.examples.startup.Init class and that the container is noticing your changes. For instance, add some logging to that class and see if your message is printed to the log.
(I note that the final line you added, while sufficient to expose a scoped attribute to your JSP page and thus to JSP, doesn't end with a ";", which might indicate you didn't recompile the class.)
