• 3步把您的java程序转换为webservice


    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>
