Hi I wanted to check if this setting in Server.xml is still valid,
<Valve className="org.apache.catalina.valves.CrawlerSessionManagerValve" crawlerUserAgents="*[bB]ot.*|.*Yahoo! Slurp.*|.*Feedfetcher-Google.*." sessionInactiveInterval="180"/> <Valve className=" org.apache.catalina.valves. DeadThreadDetectionValve" threshold="300"/> I edited by server xml and added these valves,but I adding tomcat refuses to start up and I see for some reasons Tomcat is not able to find those classes. Do I need do download some jar files to make it work ? I am looking for these valves just to make sure that I collect valid data from crawlers. and manage long running threads. - Kiran
