Subject: Re: Error calling a SOAP service from within a Rails controller

thanks, I've tried using ActionWebService::Client::SOAP, but I get the
same error (pretty much), here's the version of the method within my
Controller that used ActionWebService:

def get_weather
               lat = params[:lat]
               lon = params[:lon]
		t = Time.now
		starter = Time.local(t.year,t.mon, t.day) + (24 *3600)
		ender = starter + 7 * 24 *3600
	
		params = WeatherParametersType.new({:maxt => false, :mint => false,
:temp => true, :dew => false,
	  		:pop12 => false, :qpf => false, :sky => false, :snow => false,
	  		:wspd => false, :wdir => false, :wx => false, :waveh => false,
	  		:icons => false, :rh => false, :appt => true})
	  		
	  	soap_client = ActionWebService::Client::Soap.new(WeatherAPI,
"http://www.weather.gov/forecasts/xml/SOAP_server/ndfdXMLserver.php")
	  	@dwml = soap_client.NDFDgen(lat, lon, 'time-series', starter, ender, params)
	  	@data = @dwml
    end

and I'm using these classes I've defined:

class WeatherParametersType < ActionWebService::Struct
    member :maxt, :boolean
    member :mint, :boolean
    member :temp, :boolean
    member :dew, :boolean
    member :pop12, :boolean
    member :qpf, :boolean
    member :sky, :boolean
    member :snow, :boolean
    member :wspd, :boolean
    member :wdir, :boolean
    member :wx, :boolean
    member :waveh, :boolean
    member :icons, :boolean
    member :rh, :boolean
    member :appt, :boolean
end

	
class WeatherAPI < ActionWebService::API::Base
	api_method :NDFDgen, :expects => [[Float], [Float], [String], [Time],
[Time], [WeatherParametersType]], :returns => [String]
end

The error stack trace:
