毕业设计的时候涉及了webservice的相关内容，现在重新开始探索，把开始的东西整理一下吧，以便有人查阅～

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_PATHAxis-versionwebapps下的Axis包拷贝到TOMCAT_HOMEwebapps下，以下约定Axis_HOME为该TOMCAT_HOMEwebappsAxis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HelloClient



public 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";
            Servi
ceFactory 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
            <deployment xmlns=
            "http://xml.apache.org/Axis/wsdd/"
            xmlns:java=
            "http://xml.apache.org/Axis/wsdd/providers/java">
            <handler name="print" type="java:LogHandler"/>
            <service name="sayhello"
            provider="java:RPC">
            <requestFlow>
            <handler type="print"/>
            </requestFlow>
            <parameter name="className"
            value="server.SayHello"/>
            <parameter name="allowedMethods"
            value="*"/>
    &n
bsp;       </service>
            </deployment>



3、将编译后的文件拷贝到Axis_HOME/WEB-INF/classes下，如：D: omcatwebappsAxisWEB-INFclasses

4、发布服务：

java org.apache.Axis.client.AdminClient deploy.wsdd

5、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);
            }
            }
            }
