Axis1.4之即时发布服务

下载axis1.4开发包，解压开发包，将webapps目录下的axis文件夹拷贝到tomcat的webapps目录下。启动tomcat，在浏览器输入http://localhost:8080/axis得到如下页面:

使用axis的发布服务平台，创建和发布WebService服务有两种方式：即时发布和定制发布。即时发布服务很少用，但是为了知识体系的完整性，这里还是讲一下。本篇文章只讲即时发布服务。

写一个没有包的Java类HelloWS.java:

 public class HelloWS
 {
     public String test(String a,String b){
         String result = "a="+a+" b="+b;
         return "server response ok ,u send "+result;
     }
 }

然后将此文件拷贝到tomcat_home\webapps\axis目录下，并将文件后缀改为jws。在浏览器输入http://localhost:8080/axis/HelloWS.jws得到如下页面：

点击链接，浏览器展现一个wsdl文档：

 <wsdl:definitions xmlns:apachesoap="http://xml.apache.org/xml-soap" xmlns:impl="http://localhost:8080/axis/HelloWS.jws" xmlns:intf="http://localhost:8080/axis/HelloWS.jws" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" targetNamespace="http://localhost:8080/axis/HelloWS.jws">

 </wsdl:port>
 </wsdl:service>
 </wsdl:definitions>

这就已经发布了服务。下面我们测试一下：我们新建一个Java工程，导入axis1.4开发包下的所有jar，然后写一个测试类Client：

 package com.client;  

 import java.rmi.RemoteException;  

 import javax.xml.namespace.QName;
 import javax.xml.rpc.ServiceException;  

 import org.apache.axis.client.Call;
 import org.apache.axis.client.Service;  

 public class Client {  

     public static void main(String[] args) throws ServiceException, RemoteException {  

         String url = "http://localhost:8080/axis/HelloWS.jws";
         Service service = new Service();
         Call call = (Call) service.createCall();
         call.setTargetEndpointAddress(url);
         call.setOperationName(new QName(url,"test"));
         String result = (String) call.invoke(new Object[]{"Tomcat","Jetty"});
         System.out.println(result);
     }  

 }  

运行，控制台输出：

这就是即时发布。即时发布在实际应用中几乎不用。下篇文章我们讨论如何利用Apache提供的axis服务平台发布定制服务。
