使用Axis开发WebService

一、Axis安装1.测试环境    JDK 1.5Servlet Container: Tomcat 5.5 2.下载地址:http://ws.apache.org/axis/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.设置classpath编写setEnv.bat:

set AXIS_HOME=$AXIS_UNZIP_HOMEset CLASSPATH=.;%AXIS_HOME%/lib/axis.jar;%AXIS_HOME%/lib/axis-ant.jar;%AXIS_HOME%/lib/commons-discovery-0.2.jar;%AXIS_HOME%/lib/commons-logging-1.0.4.jar;%AXIS_HOME%/lib/jaxrpc.jar;%AXIS_HOME%/lib/saaj.jar;%AXIS_HOME%/lib/wsdl4j-1.5.1.jar;%AXIS_HOME%/lib/log4j-1.2.8.jar;E:/thirdparty/activation/activation.jar;E:/thirdparty/activation/mail.jar

 

 

 二.使用axis支持web service的部署和开发，最主要有两种方式：(一)。Dynamic Invocation Interface ( DII)1.编写服务端程序HelloClient

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

2.将源码拷贝到AXIS_HOME下，重命名为 HelloClient.jws3.访问连接http://localhost:8080/axis/HelloClient.jws?wsdl，页面显示axis自动生成的wsdl4.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();}}}

5.运行TestHelloClient测试;(二)。 Stubs方式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.";serviceHandler.setOption("accesses", numAccesses);System.out.println(result);} catch (Exception e) {throw AxisFault.makeFault;}}}

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>

4.将编译后的文件拷贝到AXIS_HOME/WEB-INF/classes下，如：D:/tomcat/webapps/axis/WEB-INF/classes5.发布服务：java org.apache.axis.client.AdminClient -h localhost -p 8080 -s /axis/servlet/AxisServlet deploy.wsdd命令参数为:

The following Options are available:        -l<url>          sets the AxisServlet URL        -h< hostName     sets the AxisServlet host        -p<portNumber>   sets the AxisServlet port        -s<servletPath>  sets the path to the AxisServlet        -f<fileName>     specifies that a simple file protocol should be used        -u<username>     sets the username        -w<password>     sets the password        -d              sets the debug flag (for instance, - ddd would set it to3 )        -t<name>         sets the transport chain touseCommands:        list            will list the currently deployed services        quit            will send a quit message to SimpleAxisServer        passwd          value changes the admin passwordDeployment Descriptor files:<deployment-descriptor-files>  deploys or undeploys Axis components andweb services described in these filesIf -l or -h -p - s are not set, the AdminClient will invokehttp://localhost:8080/axis/servlet/AxisServlet

6.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 stubjava org.apache.axis.wsdl.WSDL2Java -p client http://localhost:8080/axis/services/SayHello.jws?wsdlb:方式2  执行如下命令生成SayHello.wsdljava 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.java2。SayHelloService.java。3。SayHelloServiceLocator.java4。SayHelloSoapBindingStub.java7.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);}}}  

8.开发自己的WEB应用程序的web service ,需要在描述文件WEB-INF/web.xml文件中添加:

<listener>          <listener-class>org.apache.axis.transport.http.AxisHTTPSessionListener</listener-class>      </listener>        <servlet>      <servlet-name>AxisServlet</servlet-name>      <display-name>Apache-Axis Servlet</display-name>      <servlet-class>         org.apache.axis.transport.http.AxisServlet     </servlet-class>    </servlet>    <servlet>      <servlet-name>AdminServlet</servlet-name>      <display-name>Axis Admin Servlet</display-name>      <servlet-class>         org.apache.axis.transport.http.AdminServlet     </servlet-class>      <load-on-startup>100</load-on-startup>    </servlet>    <servlet>      <servlet-name>SOAPMonitorService</servlet-name>      <display-name>SOAPMonitorService</display-name>      <servlet-class>         org.apache.axis.monitor.SOAPMonitorService     </servlet-class>      <init-param>        <param-name>SOAPMonitorPort</param-name>        <param-value>5001</param-value>      </init-param>      <load-on-startup>100</load-on-startup>    </servlet>    <servlet-mapping>      <servlet-name>AxisServlet</servlet-name>      <url-pattern>/servlet/AxisServlet</url-pattern>    </servlet-mapping>    <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>    <servlet-mapping>      <servlet-name>SOAPMonitorService</servlet-name>      <url-pattern>/SOAPMonitor</url-pattern>    </servlet-mapping>
