Client

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

package eBay;
                                                                           
import javax.naming.InitialContext;
                                                                           
public class Client
{
    public static void main(String[] args) throws Exception
    {
    |   String auc = args.length > 0 ? args[0] : "1239594630";
    |   InitialContext ctx = new InitialContext();
    |   EBayWatcherService service = (EBayWatcherService)
    |       ctx.lookup("xmlrpc:soap:eBay.EBayWatcherService");
    |   EBayWatcherPortType eBay = service.getEBayWatcherPort();
    |   System.out.println("price on " + auc + " is $" +
    |       eBay.getCurrentPrice(auc));
    }
}

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