Hi, all, my task is using rational robot and testmanger to automate stress testing for web application. first, I record VU script, then play it back from a suite in testmanager. without applet application. this working fine. But there is a "document viewer', which is java applet application inside my web application. for any operation related to this applet application, it shows unknown protocol when I playback the VU script. can anybody here tell me how to stress testing a webapp with applet using rational products? many Thanks
