Tomcat 7 CometProcessor上缺少彗星事件

Question

I am using CometProcessor to implement long-polling on Tomcat 7.0. The thing that bothering me is I don't get any other events except CometEvent.EventType.BEGIN. The code sample:

    @Override
    public void event(CometEvent event) throws IOException, ServletException {

    HttpServletRequest request = event.getHttpServletRequest();
    HttpServletResponse response = event.getHttpServletResponse();
    if (event.getEventType() == CometEvent.EventType.BEGIN) {
        LOGGER.info("Begin for session: " + request.getSession(true).getId());
    } else if (event.getEventType() == CometEvent.EventType.ERROR) {
        LOGGER.error("Error for session: " + request.getSession(true).getId());
        event.close();
    } else if (event.getEventType() == CometEvent.EventType.END) {
        LOGGER.info("End for session: " + request.getSession(true).getId());
        event.close();
    } else if (event.getEventType() == CometEvent.EventType.READ) {
        LOGGER.info("Read from session: " + request.getSession(true).getId());
    }

I assume it could cause memory leaks because on the BEGIN event I store the response object in my local array.

Does any one have any ideas what could be wrong?

Seems there is nothing to invoke the request end so it will just sit there until a timeout occurs. In my experience, END is triggered when you call close, outside the context of the thread that calls begin.
