communication from httpsession with jsf, please give me a hand
hi man, i am making a hits count, i want to insert begintime into database when a session created. and insert into endtime when it destoryed.
i have puzzled by communication from httpsession with jsf.
i think it is diffcult to say hello to jsf from httpsession code. but any solution can result?
my code belows:
//OnlineCounterListener.java
public class OnlineCounterListener implements HttpSessionListener {
private MyTestFinder myTestFinder;
public void sessionCreated(HttpSessionEvent hse) {
myTestFinder = (MyTestFinder) Component.getInstance("myTestFinder");
if(myTestFinder!=null)
myTestFinder.createMyTest();
System.out.println("--------------------------hello jsf i love you!");
}
public void sessionDestroyed(HttpSessionEvent hse) {
}
}
