RE: Tomcat 4.0.4 Performance - PROBLEM
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:

So far, Tomcat 4.0.4 with Jasper2 has passed our stress test for memory leaks.

The performance is indeed much better.
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.

Oooo, Peter is right. Add ant.jar to the lib folder also.
Thanks Peter.

hi victor,
it worked fine for me with tomcat 4.0.3 and jasper2 on win2k. It looks
like it couldn't load something. Did you delete the working folders
maybe? Here is the generated file I got.

For this Jasper 2 build (fairly old, and has a bug), you need to have a
/WEB-INF/lib folder (even if it is empty). This got fixed since then.
