tomcat valve - Extends ValveBase class : java.lang.ClassNotFoundException -

i have created 1 web base of operations application in java , used valvebase class of java. code below :

public class renewsessionvalve extends valvebase { private string authenticationurl = "j_security_check"; @override public void invoke(request req, response res) throws ioexception, servletexception { // todo auto-generated method stub system.out.println("invoke in sessionfixationvalve "+req.getrequesturi()); if (req.getrequesturi().contains(authenticationurl)) { // save old session session oldsession = req.getsessioninternal(true); savedrequest saved = (savedrequest) oldsession. getnote(constants.form_request_note); system.out.println("before invalidating session"); // invalidate old session req.getsession(true).invalidate(); req.setrequestedsessionid(null); req.clearcookies(); system.out.println("after invalidating session"); // create new session , set request session newsession = req.getsessioninternal(true); req.setrequestedsessionid(newsession.getid()); system.out.println("saved obj : "+saved); // re-create info old session // new 1 if (saved != null) { newsession.setnote(constants.form_request_note, saved); } } system.out.println("before invoke"); // after processing request forwards getnext().invoke(req, res); } }

now compiled file , create jar file of project , set lib folder of server. part of server.xml file changed :

<host appbase="webapps" autodeploy="false" name="localhost" unpackwars="true" xmlnamespaceaware="false" xmlvalidation="false" deployonstartup="false" deployxml="false"> <valve classname="com.cmc.renewsessionvalve" /> </host>

now create 1 new project , run it. gives me error below :

this might due have placed jar in wrong server directory.
