session - Tracking user activity in Java EE -

i track user's sessions. interested in getting user logname, context accessed , time when accessed context.

i thinking of using class implements httpsessionlistener (overriding sessioncreated(final httpsessionevent se) , sessiondestroyed(final httpsessionevent se)) on these methods don't access request (from pull user's logname , context accessed).

any suggestions welcome.

i think servlet filter more suitable want. suggest write custom filter around urls want track.

in dofilter() method have access httpservletrequest needed. request object can httpsession too.

here example:

@webfilter("/*") public class trackingfilter implements filter {      private filterconfig filterconfig;      @override     public void init(filterconfig config) throws servletexception {         this.filterconfig = config;     }      @override     public void dofilter(servletrequest req, servletresponse res,                filterchain chain) throws ioexception, servletexception {         httpservletrequest request = (httpservletrequest) req;         httpsession session = request.getsession(false);          string loggedinuser = "unregistered user";          //assuming have session attribute named user username         if(session != null && session.getattribute("user") != null) {             loggedinuser = (string) session.getattribute("user");         }          date accesseddate = new date();         filterconfig.getservletcontext().log(                 string.format("%s accessed context %s on %tf %tt",                         loggedinuser, request.getrequesturi() ,                                accesseddate, accesseddate)         );          chain.dofilter(req, res);     }      @override     public void destroy() {     } }
