java axis web service

编写 java调用web service的客户端比较简单，其中webservice为上一篇gsoap创建的server。

 1 package clientTest;
 2 import java.rmi.RemoteException;  
 3 
 4 import javax.xml.namespace.QName;  
 5 import javax.xml.rpc.ServiceException;  
 6 import javax.xml.rpc.ParameterMode;
 7 import javax.xml.rpc.encoding.XMLType;
 8 
 9 import org.apache.axis.client.Call;
10 import org.apache.axis.client.Service; 
11 public class ClientTest
12 {
13     public static void main(String[] args) {  
14         try {  
15             String endpoint = "http://localhost:8080";   
16             Service service = new Service();   
17             Call call = (Call)service.createCall();   
18             call.setTargetEndpointAddress(endpoint);      
19   
20             call.setOperationName(new QName(
21                     "urn:calculator", "add"));   
22             call.addParameter("a",XMLType.SOAP_DOUBLE,ParameterMode.IN);
23             call.addParameter("b", XMLType.SOAP_DOUBLE, ParameterMode.IN);
24             call.setReturnClass(Double.class);   
25             Double temp = (Double)call.invoke(new Object[]{2,2});   //传入的参数（a、b），返回的类型为Double
26             System.out.println("result: " + temp);  
27         } catch (ServiceException e) {  
28             // TODO Auto-generated catch block  
29             e.printStackTrace();  
30         } catch (RemoteException e) {  
31             // TODO Auto-generated catch block  
32             e.printStackTrace();  
33         }  
34     }  
35 }

所对应的wsdl文件如下：

程序结构如图：

添加的jar下载地址为java_webservice(注意文件类型，javarpc-api独立一个，其余的均在axis压缩包中)。
