jetty的一个小程序

用jetty写了一个小程序,主要是解决局域网内很多人不能上网的问题.我的想法是通过一台可以上网的主机,启动这个服务.其他人访问他就可以浏览网页.写的很糙.不过能跑,有的页面还是有问题.

思路:

浏览器   -->    jetty服务,httpclient(这里的url写死的 http://www.google.cn/search?q= 查询内容)   -->   google
浏览器   <--    这里有流操作,把一些url替换掉                                                    <--   google

一下都是一样的,还有翻页也没写. get提交加一个 属性start=0 或10 20 ...   

不过感觉很慢,就是随便写着玩的.  希望大家给点意见.  

图片为要导入的包.
