2 Currency Client

If you invoke wsdl2java on the above WSDL document, you can run this client to interact with the service:
package currency;
                                                                           
import javax.naming.InitialContext;
                                                                           
public class Client
{
    public static void main(String[] args) throws Exception
    {
    |   InitialContext ctx = new InitialContext();
    |   CurrencyExchangeService service =(CurrencyExchangeService)
    |       ctx.lookup("xmlrpc:soap:currency.CurrencyExchangeService");
    |   CurrencyExchangePortType exchange = service.getCurrencyExchangePort();
    |   System.out.println("getRate = " + exchange.getRate("USA" , "japan"));
    }
}
