以及需要用到Http方式和Openfire通信的第三方库（JabberHTTPBind）。
JabberHTTPBind是jabber提供的XMPP协议通信的Http bind发送的形式，它可以完成WebBrowser和Openfire建立长连接通信。

下面这段代码尤为重要，它是设置你链接openfire的地址。这个地址一段错误你将无法进行通信！
<script type="text/javascript">
window.contextPath = "<%=path%>";
window["serverDomin"] = "192.168.8.22";
</script>
$.WebIM方法是主函数，用它可以覆盖local.chat中的基本配置，它可以完成聊天窗口的创建。$.WebIM.newWebIM方法是新创建一个窗口，只是消息的接收者是一个新用户。
$.WebIM({
sender: userName,
receiver: receiver
});
$.WebIM.newWebIM({
receiver: receiver
});
remote.jsjac.chat.login(document.userForm);方法是用户登录到Openfire服务器
参数如下：
httpbase: window.contextPath + "/JHB/", //请求后台http-bind服务器url
domain: window["serverDomin"], //"192.168.5.231", // 192.168.5.231 当前有效域名
username: "", // 登录用户名
pass: "", // 密码
timerval: 2000, // 设置请求超时
resource: "WebIM", // 链接资源标识
register: true // 是否注册
remote.jsjac.chat.logout();是退出、断开openfire的链接

这里的方法基本上是聊天窗口上的应用，主要是本地聊天程序的js、HTML元素的操作。如字体、字体大小、颜色、表情、消息的发送等，不涉及到聊天消息发送的核心代码，其中有用到发送远程消息的方法。
remote.jsjac.chat.sendMessage(text, receiver); 这个是发送远程消息的方法，参数1是消息内容、参数2是消息的接收者
如果你有看到这篇文章http://www.cnblogs.com/hoojo/archive/2012/06/18/2553886.html 它是一个单纯的WebIM本地的聊天界面。
3、远程聊天JavaScript核心代码，它是和jsjac库关联的。

至此，这个应用的全部代码已经贴出来，如果你按照我这边的结构形式应该是可以完成这个聊天应用的。如果你有什么问题或想法，欢迎你给我留言或评论！
JabberHTTPBind是jabber提供的XMPP协议通信的Http bind发送的形式，它可以完成WebBrowser和Openfire建立长连接通信。
主要通信流程如下图所示：
用户A通过JavaScript jsjac.js库发送一条消息到JabberHTTPBind这个Servlet容器，然后JabberHTTPBind的Servlet容器会向Openfire发送XMPP协议的XML报文。Openfire Server接收到报文后解析，然后发送给指定的用户B。JabberHTTPBind获取到Openfire Server发送的数据后，解析报文向当前Servlet容器中的链接的Session中找到指定的用户再发送数据给用户B。
WebBrowser端用的是jsjac和JabberHTTPBind建立的连接，所有数据都要经过JabberHTTPBind解析/转换发送给Openfire。
先上张图看看效果，呵呵~这里是用户hoojo和girl的聊天画面，双方在进行互聊……
可以发送表情、改变字体样式（对方界面也可以看到你的字体样式），同时右侧是显示/收缩详情的信息
收缩详情
聊天界面部分截图
用户登录、注册，sendTo表示你登录后向谁发送聊天消息、并且建立一个聊天窗口
登录成功后，你可以在日志控制台看到你的登陆状态、或是在firebug控制台中看到你的连接请求状态
登陆失败
只有connecting，就没有下文了
登陆成功后，你就可以给指定用户发送消息，且设置你想发送消息的新用户点击new Chat按钮创建新会话
如果你来了新消息，在浏览器的标题栏会有新消息提示
如果你当前聊天界面的窗口都是关闭状态，那么在右下角会有消息提示的闪动图标
这里已经贴出了所有的源代码了，如果你非常的需要源代码（但我希望你能自己创建一个工程去复制源代码，这是我希望看到的），那么你可以通过以下方式联系我

下面这段代码尤为重要，它是设置你链接openfire的地址。这个地址一段错误你将无法进行通信！
复制代码 代码如下:
<script type="text/javascript">
window.contextPath = "<%=path%>";
window["serverDomin"] = "192.168.8.22";
</script>
$.WebIM方法是主函数，用它可以覆盖local.chat中的基本配置，它可以完成聊天窗口的创建。$.WebIM.newWebIM方法是新创建一个窗口，只是消息的接收者是一个新用户。
复制代码 代码如下:
$.WebIM({
sender: userName,
receiver: receiver
});
$.WebIM.newWebIM({
receiver: receiver
});
remote.jsjac.chat.login(document.userForm);方法是用户登录到Openfire服务器
参数如下：
httpbase: window.contextPath + "/JHB/", //请求后台http-bind服务器url
domain: window["serverDomin"], //"192.168.5.231", // 192.168.5.231 当前有效域名
username: "", // 登录用户名
pass: "", // 密码
timerval: 2000, // 设置请求超时
resource: "WebIM", // 链接资源标识
register: true // 是否注册
remote.jsjac.chat.logout();是退出、断开openfire的链接

这里的方法基本上是聊天窗口上的应用，主要是本地聊天程序的js、HTML元素的操作。如字体、字体大小、颜色、表情、消息的发送等，不涉及到聊天消息发送的核心代码，其中有用到发送远程消息的方法。
remote.jsjac.chat.sendMessage(text, receiver); 这个是发送远程消息的方法，参数1是消息内容、参数2是消息的接收者
如果你有看到这篇文章http://www.cnblogs.com/hoojo/archive/2012/06/18/2553886.html 它是一个单纯的WebIM本地的聊天界面。
3、远程聊天JavaScript核心代码，它是和jsjac库关联的。

这个文件的代码就是用jsjac库和openfire建立通信的核心代码，代码中已经有注释，这里我就不再赘述。如果有什么不懂的可以给我留言。
4、消息区域、编辑器代码 send.message.editor-1.0.js
复制代码 代码如下:
/**

**/
var agent = window.navigator.userAgent.toLowerCase();
var sendMessageEditor = {
// 获取iframe的window对象
getWin: function () {
return /*!/firefox/.test(agent)*/false ? sendMessageEditor.iframe.contentWindow : window.frames[sendMessageEditor.iframe.name];
},
//获取iframe的document对象
getDoc: function () {
return !/firefox/.test(agent) ? sendMessageEditor.getWin().document : (sendMessageEditor.iframe.contentDocument || sendMessageEditor.getWin().document);
},
init: function (userJID) {
//打开document对象，向其写入初始化内容，以兼容FireFox
var doc = sendMessageEditor.getDoc();
doc.open();
var html = [

},

//获取编辑器的body对象
var body = doc.body || doc.documentElement;
//获取编辑器的内容
var content = body.innerHTML;
//对内容进行处理，例如替换其中的某些特殊字符等等
//Some code
//返回内容
return content;
},
//统一的执行命令方法
execCmd: function (cmd, value, d){
var doc = d || sendMessageEditor.getDoc();
//doc对象的获取参照上面的代码
//调用execCommand方法执行命令
doc.execCommand(cmd, false, value === undefined ? null : value);
},
getStyleState: function (cmd) {
var doc = sendMessageEditor.getDoc();
//doc对象的获取参考上面的对面
//光标处是否是粗体
var state = doc.queryCommandState(cmd);
if(state){
//改变按钮的样式
}
return state;
},
insertAtCursor: function (text, d, w){
var doc = d || sendMessageEditor.getDoc();
var win = w || sendMessageEditor.getWin();
//win对象的获取参考上面的代码
if (/msie/.test(agent)) {
win.focus();
var r = doc.selection.createRange();

r.collapse(true);

}
} else if (/gecko/.test(agent) || /opera/.test(agent)) {

5、css样式 chat-2.0.css
