JMeter just generates HTTP requests for a web site. It doesn't matter which technology the web site was built in - JSP, ASP, PHP, HTML etc.). Am I right in saying that "Event Functions" are clientside scripts? If so, JMeter does not have a script interpreter so can't run any clientside scripts. Normally you would write requests to simulate each of the possible outcomes of these scripts to test the web site's behaviour.
(By the way - this question has nothing to do with Apache/Tomcat. You should really have posted it in the Testing forum). [ June 22, 2005: Message edited by: Paul Sturrock ]
