用Soap消息调用Web Services（续）

      上篇《用Soap消息调用Web Services》只是简单的调用一个返回值为String的无参数WebService，这次改成调用一个参数为int型的返回值为一个类对象的WebService

 

服务器端WebService：

public   class  user implements Serializable
{
    private String name;    
    public user()
    {
        
    }
    public String getName() {
        return name;
    }
    public void setName(String name) {
        this.name = name;
    }
    
}

public   class  classDemo implements Serializable
{
    private user[] users;

    public user[] getUsers() {
        return users;
    }

    public void setUsers(user[] users) {
        this.users = users;
    }
}

public   class  HelloWorldServiceImpl implements IHelloWorldService 
{

    public  classDemo GetUsersInRoom(int rID)
    {
        classDemo cd = new classDemo();
        user[] a = new user[2];
        a[0] = new user();
        a[0].setName("aa");
        a[1] = new user();
        a[1].setName("bb");
        cd.setUsers(a);
        return cd;
    }
    
}

客户端代码：

public   static   void  doSoapPost()
     {
        try 
        {
             //First create the connection
             SOAPConnectionFactory soapConnFactory = 
                                SOAPConnectionFactory.newInstance();
             SOAPConnection connection = 
                                 soapConnFactory.createConnection();
             
             //Next, create the actual message
             MessageFactory messageFactory = MessageFactory.newInstance();
             SOAPMessage message = messageFactory.createMessage();
             
             //Create objects for the message parts            
             SOAPPart soapPart = message.getSOAPPart();
             SOAPEnvelope envelope = soapPart.getEnvelope();
             SOAPBody body = envelope.getBody();       
             
            //Populate the Message
            StreamSource preppedMsgSrc = new StreamSource( 
                     new FileInputStream("E:\\soap.msg"));
            soapPart.setContent(preppedMsgSrc);
             //Save the message
             message.saveChanges();
             //Check the input
             System.out.println("\nREQUEST:\n");
             message.writeTo(System.out);
             System.out.println();
            //Send the message and get a reply   
                
            //Set the destination
            String destination = 
                  "http://localhost:8080/HelloWorld/services/HelloWorldService";
            //Send the message
            SOAPMessage reply = connection.call(message, destination);
            
//          Check the output
            System.out.println("\nRESPONSE:\n");
            //Create the transformer
            TransformerFactory transformerFactory = 
                               TransformerFactory.newInstance();
            Transformer transformer = 
                            transformerFactory.newTransformer();
            //Extract the content of the reply
            Source sourceContent = reply.getSOAPPart().getContent();
            //Set the output for the transformation
            StreamResult result = new StreamResult(System.out);
            
            transformer.transform(sourceContent, result);
            System.out.println();
             //Close the connection            
             connection.close();
        } 
        catch(Exception e) 
        {
                System.out.println(e.getMessage());
        }   
    }

客户端Soap请求格式：

REQUEST:
<? xml version = " 1.0 "  encoding = " UTF-8 " ?>
< soap:Envelope xmlns:soap = " http://schemas.xmlsoap.org/soap/envelope/ "  xmlns:xsd = " http://www.w3.org/2001/XMLSchema "  xmlns:xsi = " http://www.w3.org/2001/XMLSchema-instance " >
< soap:Body >
< ns1:GetUsersInRoom xmlns:ns1 = " http://phinecos.cnblogs.com " >
< in0 xsi:type = ' xsd:int ' > 3
</ in0 >  
</ ns1:GetUsersInRoom >
</ soap:Body >
</ soap:Envelope >

服务器端响应结果：
