走在架構師的大道上 Jack.Wang's home

         1、 檢查Java類的方法和默認構造函數確保為public

　    2、 增加XFire servlet相關條目到web.xml中

　    3、 創建services.xml，把它放到WEB-INF/classes/META-INF/xfire目錄下

　    4、 增加XFire和第三方包到你的Web應用的WEB-INF/lib文件夾中

          實際例子:
 0. 定義 web.xml
      <servlet>
        <servlet-name>XFireServlet</servlet-name>
        <display-name>XFire Servlet</display-name>
        <servlet-class>org.codehaus.xfire.transport.http.XfireConfigurableServlet
         </servlet-class>
    </servlet><servlet-mapping>
        <servlet-name>XFireServlet</servlet-name>
        <url-pattern>/servlet/XFireServlet/*</url-pattern>
    </servlet-mapping>    
    <servlet-mapping>
        <servlet-name>XFireServlet</servlet-name>
        <url-pattern>/services/*</url-pattern>
    </servlet-mapping>
 1. 定義接口           

public interface IBankingService { 

    public String transferFunds(
        String fromAccount, String toAccount, double amount, String currency);
       
}

2.定義實現

import java.text.NumberFormat;
import java.text.DecimalFormat;

/** XFire WebServices sample implementation class.
*/
public class BankingService implements IBankingService {
   
    //Default constructor.
    public BankingService(){   
    }
   
    /** Transfers fund from one account to another.
    */
    public String transferFunds(
        String fromAccount, String toAccount, double amount, String currency){
       
        String statusMessage = "";
                     
        //Call business objects and other components to get the job done.
        //Then create a status message and return.
        try {
            NumberFormat formatter = new DecimalFormat("###,###,###,###.00");      
            statusMessage = "COMPLETED: " + currency + " " + formatter.format(amount)+
            " was successfully transferred from A/C# " + fromAccount + " to A/C# " + toAccount;
        } catch (Exception e){
            statusMessage = "BankingService.transferFunds(): EXCEPTION: " + e.toString();
        }
        return statusMessage;
    }
   
}

3. 定義 web 描述
<beans xmlns="http://xfire.codehaus.org/config/1.0">
 
  <service>
    <name>Banking</name>
    <namespace>mybank</namespace>
    <serviceClass>com.mybank.xfire.example.IBankingService</serviceClass>
    <implementationClass>com.mybank.xfire.example.BankingService</implementationClass>
  </service> 
 
</beans>
4.部署獲得WSDL
    WSDL的URL應該是:http://localhost:8080/websvc/services/Banking?wsdl。
5. 開發客戶端
//Create a metadata of the service     
        Service serviceModel = new ObjectServiceFactory().create(IBankingService.class);       
        log.debug("callSoapServiceLocal(): got service model." );
  
        //Create a proxy for the deployed service
        XFire xfire = XFireFactory.newInstance().getXFire();
        XFireProxyFactory factory = new XFireProxyFactory(xfire);     
   
        String serviceUrl = "http://localhost:8080/websvc/services/Banking";
       
        IBankingService client = null;
        try {
            client = (IBankingService) factory.create(serviceModel, serviceUrl);
        } catch (MalformedURLException e) {
            log.error("WsClient.callWebService(): EXCEPTION: " + e.toString());
        }   
              
        //Invoke the service
        String serviceResponse = "";
        try {
            serviceResponse = client.transferFunds(fromAccount, toAccount, amount, currency);
       } catch (Exception e){
            log.error("WsClient.callWebService(): EXCEPTION: " + e.toString());                
            serviceResponse = e.toString();
        }
