Axis 

配置:

1,axis本身可以servlet的形式集成到任何支持servlet的Web容器(web.xml)

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

2,当然需要让Web容器找到org.apache.axis.transport.http.AxisServlet

将axis所需库和资源配置到classpath里面
或者将axis的lib目录拷贝到WEB-INFO下

3,然后让axis接管WebService的url(web.xml)

- < 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 >

4,剩下的只需要告诉axis每个WebService对应着哪个Java类即可(server-config.wsdd(与web.xml同目录))

- < service name =" OrganizationWebService " type ="" provider =" java:RPC " style ="rpc " use ="encoded ">
  < parameter name ="scope " value ="Request " />
  < parameter name =" className " value =" nucleus.organization.webservice.OrganizationWebService " />
  < parameter name =" allowedMethods " value =" isValid, personOfID, personsOfRole, queryCategories, queryPersons " />
  < namespace > http://webservice.organization.nucleus </ namespace >
  < typeMapping encodingStyle ="http://schemas.xmlsoap.org/soap/encoding/ " qname ="ns1:CategoryInfo " languageSpecificType ="java:nucleus.organization.webservice.CategoryInfo " serializer ="org.apache.axis.encoding.ser.BeanSerializerFactory " deserializer ="org.apache.axis.encoding.ser.BeanDeserializerFactory " name ="CategoryInfo " xmlns:ns1 =" http://webservice.organization.nucleus " />
  </ service >
使用:
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";

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
<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="*"/>
</service>
</deployment>


3、将编译后的文件拷贝到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);
}
}
}
