Java WebService Tomcat Apache Web

地址：http://hi.baidu.com/itpassion/blog/item/9ce50dfb4fc66065024f5673.html

1、选择要转换的java文件，生成class
2、写wsdd
3、发布

剩下的就只有调用了wsdl2java

我原来的系统是CICS的，对后台封装了一层，现在用webservice再封装一层，前台页面，控制，数据传输，数据处理统统都可以分开了，爽
//以下是从网上找的关于AXIS的入门教程

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);
          }
      }
}

您也可以写server-config.wsdd

<?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"> 
<globalConfiguration>  

    <parameter name="adminPassword" value="admin"/>  
    <parameter name="attachments.implementation" 
            value="org.apache.axis.attachments.AttachmentsImpl"/>  
    <parameter name="sendXsiTypes" value="true"/>  
    <parameter name="sendMultiRefs" value="true"/>  
    <parameter name="sendXMLDeclaration" value="true"/>  
    <parameter name="axis.sendMinimizedElements" value="true"/> 
   
    <requestFlow>   
     <handler type="java:org.apache.axis.handlers.JWSHandler">    
      <parameter name="scope" value="session"/>   
     </handler>   
   
     <handler type="java:org.apache.axis.handlers.JWSHandler">    
      <parameter name="scope" value="request"/>    
      <parameter name="extension" value=".jwr"/>   
     </handler>  
   
    </requestFlow> 
  
</globalConfiguration> 
<handler name="LocalResponder" type="java:org.apache.axis.transport.local.LocalResponder"/> 
<handler name="URLMapper" type="java:org.apache.axis.handlers.http.URLMapper"/> 
<handler name="Authenticate" type="java:org.apache.axis.handlers.SimpleAuthenticationHandler"/>   
    <handler name="print" type="java:stub.LogHandler"/>
  
    <service name="sayhello" provider="java:RPC">
     <requestFlow>
       <handler type="print"/>
     </requestFlow>
    <parameter name="className"     value="stub.server.SayHello"/>  
    <parameter name="allowedMethods"    value="*"/>  
</service>


<transport name="http">  
    <requestFlow>   
     <handler type="URLMapper"/>   
     <handler type="java:org.apache.axis.handlers.http.HTTPAuthHandler"/>  
    </requestFlow> 
</transport> 
<transport name="local">  
    <responseFlow>   
     <handler type="LocalResponder"/>  
    </responseFlow> 
</transport>
</deployment>
