Axis支持三种web service的部�|�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.�~�写服务端程序HelloClient

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

2、将源码拯��到Axis_HOME下，重命名�ؓ HelloClient.jws

3、访问连接http://localhost:8080/Axis/HelloClient.jws?wsdl�Q�页面显�C�Axis自动生成的wsdl

4、编写访问服务的客户�? 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方式讉K��服务

1、编写部�|�服务端�E�序�Q�同上边DII方式�Q�本�ơ仍使用上边部��v的HelloClient

2、编写代理接�?

public interface HelloClientInterface
extends java.rmi.Remote
{
public String getName(String name)
           throws java.rmi.RemoteException;
}

3、编写�ƈ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�Q�编写stub client讉K��web服务

1、编写服务端�E�序server,SayHello.java�Q�编译server.SayHello.java

package server;
public class SayHello
{
public String getName(String name)
{
return "hello "+name;
}
}
2.�~�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�g

deploy.wsdd
eployment xmlns=
"http://xml.apache.org/Axis/wsdd/"
xmlns:java=
                                   "http://xml.apache.org/Axis/wsdd/providers/java">
er name="print" type="java:LogHandler"/>
ervice name="sayhello"
provider="java:RPC">
equestFlow>
er type="print"/>
equestFlow>
eter name="className"
value="server.SayHello"/>
eter name="allowedMethods"
value="*"/>
ervice>
eployment>

3、将�~�译后的文�g拯��到Axis_HOME/WEB-INF/classes下，如：D:\tomcat\webapps\Axis\WEB-INF\classes

4、发布服务：

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

5、生成client stub文�g

a:方式1

��SayHello.java拯��到Axis_HOME/下，重命名�ؓSayHello.jws�Q?

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��o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��o生成client stub

java org.apache.Axis.wsdl.WSDL2Java
SayHello.wsdl -p client

生成的stub client文�g列表为：

1.SayHello.java

2.SayHelloService.java�?

3.SayHelloServiceLocator.java

4.SayHelloSoapBindingStub.java

6、编写客��L��E�序�Q�编译�ƈ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);
}
}
}
