httpclient妙用一 httpclient作为客户端调用webservice http://aperise.iteye.com/blog/2223454
httpclient妙用二 httpclient保持会话登录 http://aperise.iteye.com/blog/2223470

    }

　　

优点：

       1.使用httpclient作为客户端调用webservice，不用关注繁琐的webservice框架，只需找到SOAP消息格式，添加httpclient依赖就行。

       2.使用httpclient调用webservice，建议采用soap1.1方式调用，经测试使用soap1.1方式能调用soap1.1和soap1.2的服务端。

 

       缺点：

       唯一的缺点是，你得自己解析返回的XML，找到你关注的信息内容。
