java WebService例子

一、Axis安装 1、环境 J2SE SDK 1.3 or 1.4: 我使用 1.4.2 Servlet Container: 我使用的Tomcat 5.0 2、到 http://ws.apache.org/Axis/网站下载Axis安装包3、解压缩安装包，将Axis_UNZIP_PATH\Axis-version\webapps下的Axis包拷贝到TOMCAT_HOME\webapps\下，以下约定Axis_HOME为该TOMCAT_HOME\webapps\Axis目录4、启动tomcat,访问http://localhost:8080/Axis 检查安装是否成功5、以上步骤执行成功，可以开发webservice例子了Axis支持三种web service的部署和开发，分别为：1、Dynamic Invocation Interface ( DII)2、Stubs方式3、Dynamic Proxy方式 二、编写DII(Dynamic Invocation Interface )方式web服务 1.编写服务端程序HelloClientpublic class HelloClient
{
     public String getName(String name)
     {
         return "hello "+name;
     }
} 2、将源码拷贝到Axis_HOME下，重命名为 HelloClient.jws 3、访问连接http://localhost:8080/Axis/HelloClient.jws?wsdl，页面显示Axis自动生成的wsdl 4、编写访问服务的客户端 TestHelloClient.java import org.apache.Axis.client.Call;
import org.apache.Axis.client.Service;
import javax.xml.namespace.QName;
import javax.xml.rpc.ServiceException;
import java.net.MalformedURLException;
import java.rmi.RemoteException;public class SayHelloClient2
{
     public static void main(String[] args)
         {
         try
                 {
   String endpoint =
   "http://localhost:8080/Axis/HelloClient.jws";     Service service = new Service();
             Call call = null;             call = (Call) service.createCall();             call.setOperationName(new QName(
                "http://localhost:8080/Axis/HelloClient.jws",
                            "getName"));
             call.setTargetEndpointAddress
                         (new java.net.URL(endpoint));             String ret = (String) call.invoke(new Object[]
                         {"zhangsan"});
             System.out.println("return value is " + ret);
         }
                 catch (Exception ex)
                 {
        ex.printStackTrace();
         }
     }
}
三、编写Dynamic Proxy方式访问服务 1、编写部署服务端程序，同上边DII方式，本次仍使用上边部署的HelloClient 2、编写代理接口 public interface HelloClientInterface
extends java.rmi.Remote
{
     public String getName(String name)
         throws java.rmi.RemoteException;
}3、编写并执行客户端程序TestHelloClient.java import javax.xml.rpc.Service;
import javax.xml.rpc.ServiceFactory;
import java.net.URL;
import javax.xml.namespace.QName;public class TestHelloClient
{
     public static void main(String[] args)
         {
         try
         {
             String wsdlUrl =
                         "http://localhost:8080/Axis/HelloClient.jws?wsdl";
             String nameSpaceUri =
                         "http://localhost:8080/Axis/HelloClient.jws";
             String serviceName = "HelloClientService";
             String portName = "HelloClient";             ServiceFactory serviceFactory =
                         ServiceFactory.newInstance();
             Service afService =
                         serviceFactory.createService(new URL(wsdlUrl),
          new QName(nameSpaceUri, serviceName));
             HelloClientInterface proxy = (HelloClientInterface)
         afService.getPort(new QName(
                     nameSpaceUri, portName),
                                         HelloClientInterface.class);
             System.out.println
                         ("return value is "+proxy.getName("john") ) ;
         }catch(Exception ex)
         {
             ex.printStackTrace() ;
         }
     }
}
四、编写wsdd发布web服务，编写stub client访问web服务 1、编写服务端程序server,SayHello.java，编译server.SayHello.java package server;
public class SayHello
{
     public String getName(String name)
     {
         return "hello "+name;
     }
}
2.编写LogHandler.java
import org.apache.Axis.AxisFault;
import org.apache.Axis.Handler;
import org.apache.Axis.MessageContext;
import org.apache.Axis.handlers.BasicHandler;import java.util.Date;public class LogHandler
extends BasicHandler
{
public void invoke
(MessageContext msgContext)
throws AxisFault
     {
         /** Log an access each time
                 we get invoked.
          */
         try {
             Handler serviceHandler
                         = msgContext.getService();             Integer numAccesses =
   (Integer)serviceHandler.getOption("accesses");
             if (numAccesses == null)
                 numAccesses = new Integer(0);
numAccesses = new Integer
(numAccesses.intValue() + 1);
Date date = new Date();
String result =
date + ": service " +
msgContext.getTargetService() +
" accessed " + numAccesses + " time(s).";
serviceHandler.setOption
("accesses", numAccesses);
System.out.println(result);
         } catch (Exception e)
                 {
             throw AxisFault.makeFault(e);
         }
     }
}
3、编写wsdd文件 deploy.wsdd
"http://xml.apache.org/Axis/wsdd/"
   xmlns:java=
                         "http://xml.apache.org/Axis/wsdd/providers/java">          
   
provider="java:RPC">
   
     
   
      value="server.SayHello"/>
      value="*"/> 

4、将编译后的文件拷贝到Axis_HOME/WEB-INF/classes下，如：D:\tomcat\webapps\Axis\WEB-INF\classes 5、发布服务： java org.apache.Axis.client.AdminClient deploy.wsdd 6、生成client stub文件 a:方式1 将SayHello.java拷贝到Axis_HOME/下，重命名为SayHello.jws， 执行下面的命令生存client stub java org.apache.Axis.wsdl.WSDL2Java
-p client   http://localhost:8080
/Axis/services/SayHello.jws?wsdl
b:方式2 执行如下命令生成SayHello.wsdl java org.apache.Axis.wsdl.Java2WSDL
-oSayHello.wsdl -lhttp://localhost:8080
/Axis/services/SayHello -nsayhello server.SayHello执行如下命令生成client stub java org.apache.Axis.wsdl.WSDL2Java
SayHello.wsdl   -p client生成的stub client文件列表为： 1.SayHello.java 2.SayHelloService.java。 3.SayHelloServiceLocator.java 4.SayHelloSoapBindingStub.java 6、编写客户端程序，编译并执行 public class SayHelloClient
{
     public static void main(String[] args)
         {
         try
                 {
     SayHelloService service = new client.
        SayHelloServiceLocator();
           client.SayHello_PortType
                   client = service.getSayHello();
             String retValue=client.getName("zhangsan");
             System.out.println(retValue);
}
catch (Exception e)
{
System.err.println
("Execution failed. Exception: " + e);
         }
     }
}您也可以写server-config.wsdd

         xmlns:java="http://xml.apache.org/axis/wsdd/providers/java">
      
              value="org.apache.axis.attachments.AttachmentsImpl"/> 
    
    
    
  
  
     
       
       
      
  
       
        
       
     
  
  
 



  
  
 
  
   
     
   
    
    
 
     
      
     
  

 
     
     
  


这个更好用些
