WEB services客户端例子

说明:本文材料取自Axis user's guide在Apache的公共Axis服务器上有一个echoString的服务,你向该服务发一个串,该服务能够返回同一个串给你.下面我们写一个WEB services客户端例子来调用该服务:1   import org.apache.axis.client.Call;2   import org.apache.axis.client.Service;3   import javax.xml.namespace.QName;4   5   public class TestClient {6      public static void main(String [] args) {7          try {8              String endpoint =9                       "http://nagoya.apache.org:5049/axis/services/echo";10                 //创建两个JAX-RPC对象11             Service  service = new Service();12             Call     call    = (Call) service.createCall();13                 //SOAP消息的目的地14             call.setTargetEndpointAddress( new java.net.URL(endpoint) );               //要调用的操作名称15             call.setOperationName(new QName("http://soapinterop.org/", "echoString"));16                 //用数组形式传入参数17             String ret = (String) call.invoke( new Object[] { "Hello!" } );18  19             System.out.println("Sent 'Hello!', got '" + ret + "'");20         } catch (Exception e) {21             System.err.println(e.toString());22         }23     }24  }上面的文件在axis的D:\axis\axis-1_1\samples\userguide\example1目录下.

加入需要的包,连接上网络,运行程序,你将得到下面的结果:Sent 'Hello!', got 'Hello!'

用tcpmon或SOAP monitor工具查看传递的SOAP消息,如下:<?xml version="1.0" encoding="UTF-8"?><SOAP-ENV:Envelope xmlns:xsd="http://www.w3.org/2001/XMLSchema"                   xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"                   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">  <SOAP-ENV:Body>    <ns1:echoString xmlns:ns1="http://soapinterop.org/">      <arg0 xsi:type="xsd:string">Hello!</arg0>    </ns1:echoString>  </SOAP-ENV:Body></SOAP-ENV:Envelope>这个就是一个符合SOAP规范的文件了.
