Client

If you invoke wsdl2java on the above WSDL document, you can run this client to interact with the service:

package quote;
                                                                           
import javax.naming.InitialContext;
                                                                           
public class Client
{
    public static void main(String[] args) throws Exception
    {
    |   // check Alan Watts: The Book by default
    |   String isbn = args.length > 0 ? args[0] : "0679723005";
    |   InitialContext ctx = new InitialContext();
    |   BNQuoteService service =
    |       (BNQuoteService) ctx.lookup("xmlrpc:soap:quote.BNQuoteService");
    |   BNQuotePortType quote = service.getBNQuotePort();
    |   System.out.println(isbn + " costs $" + quote.getPrice(isbn));
    }
}

Please refer to the README file for details on how to build and run the example.
