java调用WebService(客户端)

java调用WebService（客户端）
看下了网上大部分都是写java来编写WS服务端，写了下JAVA的调用端。
WebService可以有Get、 Post、Soap、Document四种方式调用，以下是四种方式的参照说明。
name 属性 说明
HttpGet 添加HTTP GET协议 在追加到HTTP请求URL的查询字符串中传递的方法参数，格式为：?name1=value1&name2=value2...。返回值被当做简单的XML文档放入HTTP响应的正文中（没有<soap:Envelope>）。
HTTPPost 添加HTTP POST协议 在HTTP请求的正文中传递的方法参数，格式为：name1=value1&name2=value2...。返回值被当做简单的XML文档放入HTTP响应的正文中（没有< soap:Envelope>）。
HTTPSoap 添加Http Soap协议 Soap消息在HTTP请求的正文中发送；Soap响应在HTTP响应的正文中发送。
Documentation 添加特殊的Documentation协议 当在启用了此协议的情况下直接请求.asmx页时，Asp.Net运行Helper页创建HTML文档页，该文档页被传递到提出请求的客户端
对于SOAP协议多写了个CXF的调用（对于CXF必须有以下包：）

以下是调用代码
