axis第一个例子

首先安装axis和tomcat6，将axis安装目录下webapps下的axis拷贝到tomcat的webapps目录中去，并在axis\web-info\lib目录下拷贝可选的jar包
然后编写helloclient代码，然后将其拷贝到D:\Tomcat6\webapps\axis下，并命名为HelloClient.jws。

public class HelloClient { public String getName(String name) { return "hello "+name; } } 

启动tomcat，在浏览器输入：http://localhost:8080/axis/HelloClient.jws
显示以下结果：
There is a Web Service here
Click to see the WSDL
点击，可查看wsdl文件
或者输入http://localhost:8080/axis/HelloClient.jws?wsdl

wsdl文件的剖析：
<definitions>wsdl的根元素，定义web服务的名称，并声明wsdl其余部分使用的命名空间。
<types>：定义web服务于服务用户之间交换的信息的所有数据类型。XML schema是默认的类型系统。
message：表示web服务于服务用户之间传递的数据的逻辑定义，描述单向消息，包含0或多个消息元素part。part主要指请求参数或响应返回值。
portType：通过组合message定义的各种请求和响应消息，定义了web服务支持的各项操作的抽象定义。
binding：指定portType定义的操作和消息的具体协议和数据格式。
port：指定与web服务的绑定地址。
service：聚集一组相关的port元素
当输入http://localhost:8080/axis/HelloClient.jws?method=getName时，显示结果：

  <?xml version="1.0" encoding="UTF-8" ?> 
- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
- <soapenv:Body>
- <getNameResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
  <getNameReturn xsi:type="xsd:string">hello null</getNameReturn> 
  </getNameResponse>
  </soapenv:Body>
  </soapenv:Envelope>

在浏览器中输入http://localhost:8080/axis/HelloClient.jws?method=getName&parameter=luokaiyun时，显示的xml结果如下：

<?xml version="1.0" encoding="UTF-8" ?> 
- <soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
- <soapenv:Body>
- <getNameResponse soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/">
  <getNameReturn xsi:type="xsd:string">hello luokaiyun</getNameReturn> 
  </getNameResponse>
  </soapenv:Body>
  </soapenv:Envelope>

在axis的web-inf目录下还有一个server-config.wsdd文件，服务部署描述，该文件一开始没有，可以自行添加如下：

<?xml version="1.0" encoding="UTF-8"?>
<deployment xmlns="http://xml.apache.org/axis/wsdd/" xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">

 </transport>
 <transport name="local">
  <responseFlow>
   <handler type="LocalResponder"/>
  </responseFlow>
 </transport>
</deployment>

所有要部署的web服务在此文件中都有描述，有了这个文件，就可以在浏览器中输入http://localhost:8080/axis/servlet/AxisServlet，以查看可用的服务
本例子显示服务如下：
And now... Some Services
AdminService (wsdl)
AdminService
Version (wsdl)
getVersion
HelloWorld (wsdl)
sayHello

部署完服务后，可直接在浏览器中输入如：http://localhost:8080/axis/services/HelloWorld来访问helloworld服务，结果：
HelloWorld
Hi there, this is an AXIS service!

Perhaps there will be a form for invoking the service here...
