Hi guys,
I am trying to create a service that our other servlets will use. Its supposed to set itself up on ContextInitialized and clean up on ContextDestroyed.
My problem is that a key attribute I store in the ServletContext and need toa ccess for celanup is VANISHING from the attributes before ContextDestroyed get called :(
I am *positive* I am not resetting it myself. Where is it going and why???
This has been immensely frustrating to try to debug.
The code is below if anyone wants to look at it

=====================================
[code]
public class TimerManager implements ServletContextListener{
static final private Logger logger = Logger.getLogger(TimerManager.class.getName());
static final private String TIMERLIST="com.rebelmonkey.TIMERLIST";
public void contextInitialized(ServletContextEvent sce) {
logger.info("Initializing Timer Manager");
setTimerList(sce.getServletContext(),
new LinkedList<Timer>());
}
public void contextDestroyed(ServletContextEvent sce) {
logger.info("Closing Timer Manager");
List<Timer> timerList = getTimerList(sce.getServletContext());
for(Timer t : timerList){
logger.info("Canceling timer "+t);
t.cancel();
}
timerList.clear();
}
static Timer getTimer(ServletContext ctxt){
Timer timer = new Timer();
getTimerList(ctxt).add(timer);
return timer;
}
static void disposeTimer(ServletContext ctxt, Timer timer){
getTimerList(ctxt).remove(timer);
timer.cancel();
}
private static List<Timer> getTimerList(ServletContext servletContext) {
List<Timer> timerList = (List<Timer>) servletContext.getAttribute(TIMERLIST);
logger.info("Retreived attribute "+TIMERLIST+" of value "+timerList);
return timerList;
}
private static void setTimerList(ServletContext servletContext, List<Timer> list) {
logger.info("Setting attribute "+TIMERLIST+" to "+list.toString());
servletContext.setAttribute(TIMERLIST, list);
}
}
