Rails - Mar 2006 - What if a webservice is not available = "execution expired" error

Hi,

I''m using a webservice in my application. How can I make it so that my
application will only try to connect to the webservice for a certain
period of time and then give up?

Right now my code is using a begin-rescue-else but sometimes I get a
"execution expired" error if the webservice is not available or takes
too long to respond.

Thanks,
Peter


begin
  service =
SOAP::RPC::Driver.new("http://www.webservicex.net/CurrencyConvertor.asmx","http://www.webserviceX.NET/")
  service.default_encodingstyle SOAP::EncodingStyle::ASPDotNetHandler::Namespace
  service.add_method_with_soapaction("ConversionRate",
"http://www.webserviceX.NET/ConversionRate", "FromCurrency",
"ToCurrency")

  rate = service.ConversionRate("CAD",current_currency).to_f
rescue
  sprintf("$%0.2f CAN", can_amt)
 else
  case current_currency
  when "USD"
    sprintf("$%0.2f US", can_amt*rate)
  when "GBP"
    sprintf("?%0.2f", can_amt*rate)
  when "EUR"
    sprintf("?%0.2f", can_amt*rate)
  when "AUD"
    sprintf("$%0.2f AUS", can_amt*rate)
  when "MXN"
    sprintf("%0.2f Mx Pesos", can_amt*rate)
  end
end

Resolved. I found Timeout.

Thanks,
Peter
