求，pusulet的使用方法

我现在想做一个网页聊天的系统，我用的是pusulet框架，下载的别人的例子改的，也算是实现了，可是聊天时一会可以用一会发不出去信息了，控制台不定时的提示-----??? removed  ,我试着找找他出现removed客户的联接的规律，找得我头都快爆了，我怀疑我用它的方法不对，请会用的帮个忙，给俺说说怎么用，
下面我就把我做的给大家讲一下，有兴趣的朋友看看我的代码：web.xml<?xml version="1.0" encoding="UTF-8"?>

pushlet的配置文件
sources.properties ：
source2=com.test.pushlet.PustletEventpushlet.properties ：较多，等会我发个图片吧

上面那个类是PustletEvent 类，
下面这个是界面，两个：<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%><!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">
