本文介绍如何使用Axis1.4搭建WebService服务及客户端访问流程。包括配置Tomcat和JDK、设置web.xml、部署server-config.wsdd、创建HelloWorld服务示例及客户端调用方法。

webservice的框架有很多种axis1 axis2 cfx......。
其中axis1.4是比较稳定和成熟的一种。。。
一。axis的下载 http://ws.apache.org/axis/
二，jdk和tomcat的配置
三，搭建环境
1 服务端：
新建工程server_axis,解压缩axis-bin-1_4.zip把 axis-1_4\webapps\axis\WEB-INF\lib的包拷到server_axis工程的lib下面。

web.xml文件

新建server-config.wsdd文件入在WEB-INF下面

内容为：

<?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">

    </service>

   <handler type="URLMapper"/>
   <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/>
  </requestFlow>

  </responseFlow>

</deployment>

新建 HelloWorld.java

内容为：

package anni;
public class HelloWorld {
    public String sayHello() {
        return "hello world!";
    }
}

然后是在server-config.wsdd里面发布HelloWorld ，

 <service name="HelloWorld" provider="java:RPC">
  <parameter name="allowedMethods" value="*"/>
  <parameter name="scope" value="Request"/>
  <parameter name="className" value="anni.HelloWorld"/>
 </service>

2，客户端

新建工程client_axis 同样的把那些包拷过去。。。

新建HelloClient.java

package anni;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;

public class HelloClient {
    public static void main(String [] args) throws Exception {
        String endpoint = "http://localhost:9890/server_axis/services/HelloWorld";//注意！差别仅仅在这里！！
        Service service = new Service();
        Call    call    = (Call) service.createCall();
        call.setTargetEndpointAddress(new java.net.URL(endpoint));
        call.setOperationName("sayHello");
        String res = (String) call.invoke(new Object[]{});
        System.out.println(res);
   }
}

这样就OK了,客户端就可以访问到服务羰了。。当然这是最简单的一个访问了。

后面还可以加上日志，验证等。。。

看源码。。。
