There is java servlet, which contains two String variables with currency abbreviations. There is external JAX-WS service http://www.webservicex.net/ws/WSDetails.aspx?CATID=2&WSID=10 which gives currency rates. How to make request to this service? How to send him this two string variables and get number back? Using Eclipse EE Kepler, Tomcat 6

For some services in www.webservicex.net, you can do a GET request using HTTP. e.g.:
protected void doGet(HttpServletRequest request,
HttpServletResponse response) throws ServletException, IOException {
String from = "USD";
String to = "EUR";
java.net.URL url = new java.net.URL(
"http://www.webservicex.net/CurrencyConvertor.asmx"
+ "/ConversionRate?FromCurrency=" + from
+ "&ToCurrency=" + to);
java.util.Scanner sc = new java.util.Scanner(url.openStream());
// <?xml version="1.0" encoding="utf-8"?>
sc.nextLine();
// <double xmlns="http://www.webserviceX.NET/">0.724</double>
String str = sc.nextLine().replaceAll("^.*>(.*)<.*$", "$1");
sc.close();
Double rate = Double.parseDouble(str);
log("Rate: " + rate);
}
