Axis進階用法－Jemmy Walker

Axis不像iBATIS，只需引用一個jar，至少下載的Axis套件裡WEB-INF/lib的jar都要包括進去，清單如下：

activation-1.1.jar

axis-ant.jar

axis.jar

commons-discovery-0.2.jar

commons-logging-1.1.jar

jaxrpc.jar

mail-1.4.jar

saaj.jar

wsdl4j-1.6.2.jar

在去年寫的Ajaxis文章裡是簡述jws的用法，這裡是詳述server-config.wsdd用法，雖然資料久遠，但人老易忘，只能註記下：

介面：Hello.java

package server;

public interface Hello {
public String getHello(String name);
}

實作：HelloService.java

package server;
public class HelloService implements Hello
{
    public String getHello(String name)
    {
        return "Hello "+name+ "! This is AXIS Web Service Response";
    }
}

配置：web.xml (增加以下內容)

<servlet>
<servlet-name>AxisServlet</servlet-name>
<display-name>Apache-Axis Servlet</display-name>
<servlet-class>
org.apache.axis.transport.http.AxisServlet
</servlet-class>
</servlet>

<servlet-mapping>
<servlet-name>AxisServlet</servlet-name>
<url-pattern>/servlet/AxisServlet</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>AxisServlet</servlet-name>
<url-pattern>*.jws</url-pattern>
</servlet-mapping>

<servlet-mapping>
<servlet-name>AxisServlet</servlet-name>
<url-pattern>/services/*</url-pattern>
</servlet-mapping>

配置：server-config.wsdd (放在WEB-INF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">
<handler type="java:org.apache.axis.handlers.http.URLMapper" name="URLMapper"/>
  <service name="hello" provider="java:RPC">
  <parameter name="className" value="server.HelloService"/>
  <parameter name="allowedMethods" value="getHello"/>
  </service>
<transport name="http">
<requestFlow>
    <handler type="URLMapper"/>
</requestFlow>
</transport>
</deployment>

Client端測試程式：AxisWSTestor.java

package client;

import java.net.MalformedURLException;
import java.rmi.RemoteException;
import javax.xml.rpc.ServiceException;
import org.apache.axis.client.Call;
import org.apache.axis.client.Service;
public class AxisWSTestor {

public static void main(String[] args) throws ServiceException, MalformedURLException, RemoteException
{

String endpoint = "http://localhost:8080/SampleAxis/services/hello"; // SampleAxis是war name，services是servlet-mapping的/services/*，hello是server-config.wsdd的service name

        Service service = new Service();
        Call call = (Call) service.createCall();
        call.setTargetEndpointAddress( new java.net.URL(endpoint)) ;

        call.setOperationName( "getHello" );
        String res = (String) call.invoke( new Object[] {"Aihu"} );
        System.out.println( res );
}
}
