httpclient调用webService
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

maven依赖如下：

//采用SOAP1.1调用服务端，这种方式能调用服务端为soap1.1和soap1.2的服务
doPostSoap1_1(postUrl, orderSoapXml, "");
doPostSoap1_1(postUrl, querySoapXml, "");
//采用SOAP1.2调用服务端，这种方式只能调用服务端为soap1.2的服务
//doPostSoap1_2(postUrl, orderSoapXml, "order");

}
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。
