webservice:
?? ?就是应用程序之间跨语言的调用
?? ?wwww.webxml.com.cn
?? ?1.xml
?? ?2.?? ?wsdl: webservice description language web服务描述语言
?? ??? ?通过xml格式说明调用的地址方法如何调用，可以看错webservice的说明书
?? ?
?? ?3.soap simple object access protoacl (简单对象访问协议)
?? ??? ?限定了xml的格式
?? ??? ?soap 在http（因为有请求体，所以必须是post请求）的基础上传输xml数据
?? ??? ??? ?请求和响应的xml 的格式如：?? ?<Envelop>
?? ??? ??? ??? ??? ??? ??? ??? ?<body>
?? ??? ??? ??? ??? ??? ??? ??? ?//....
?? ??? ??? ??? ??? ??? ??? ??? ?</body>
?? ??? ??? ??? ??? ??? ??? ?</Envelop>
?? ??? ??? ??? ?operation name：服务提供的方法
?? ??? ??? ??? ?
?? ??? ?
?? ?静态方法不能发布为外部服务
?? ?
?? ?运用jkd自带的代码生成访问服务器的客户端代码?? ?E:/wsimort -s . http://test.cm/?wsdl
?? ?
?? ?我们可以把webservice看做是web服务器上的一个应用，web服务器是webservice的一个容器
?? ?
?? ?函数的参数在 http://test.cm/?xsd=1
?? ?
?? ?JAX-WS是指 java api for xml -WebService
?? ?
?? ?//测试 WebService服务的 explorer
?? ?Web Service Explorer 可以显示返回的xml格式
?? ?
?? ?targetNamespace 默认为倒置的包名
?? ?
客户端调用WebService的方式：
?? ?1.通过wximport生成代码
?? ?2.通过客户端编程方式
?? ?3.通过ajax调用方式
?? ?4.通过 URL Connection 方式调用


请求过程分析：
?? ??? ?1.使用get方式获取wsdl文件，称为握手
?? ??? ?2.使用post发出请求

?? ??? ?3.服务器响应成功过

bubuko.com,布布扣

几种监听工具：
?? ?http watch
?? ?Web Service explorer
?? ?eclipse 自带工具?? TCP/IP Monitor


??服务端代码：

1.客户端调用（wximport自动生成代码 【推荐】）
