[xfire-user] Calling a Web Service inside a webapp with XFire

[ying lcs]

Hi,

I am trying to call a web service inside my webapp using xfire.

As a test, I put the BookClient in my webapp.
But I get this error, can anyone please help me understand what is the problem?

I appreciate if anyone can give me some help.

Here is my code for calling the web service:


String serviceURL = "http://localhost:8080/xfire/services/BookService";;
       Service serviceModel = new
ObjectServiceFactory().create(ConfigService.class,null,"http://xfire.codehaus.org/BookService",null);

       XFireProxyFactory serviceFactory = new XFireProxyFactory();

       try
       {
           BookService service = (BookService)
serviceFactory.create(serviceModel, serviceURL);
           Client client = Client.getInstance(service);
           client.addOutHandler(new OutHeaderHandler());
           Book[] books = service.getBooks();
           Map booksMap = service.getBooksMap();
           System.out.print("Received map with "+booksMap.size()+"
book(s) \n");
           System.out.println("BOOKS:");

           for (int i = 0; i < books.length; i++)
           {
               System.out.println(books[i].geAuthor());


           }

           service.clearCache();

       }
       catch (Exception e)
       {
           e.printStackTrace();
       }
