SOAP (NDFD weather web service) question

Hi,

Did by any chance anybody get the NDFD weather web service
(http://www.nws.noaa.gov/forecasts/xml/#use_it) to work in Ruby? Being
new to SOAP/Ruby, here is what I (unsuccessfully) tried:

require ‘soap/rpc/driver’
ndfd =
SOAP::RPC::Driver.new(‘http://www.weather.gov/forecasts/xml/SOAP_server/ndfdXMLserver.php’,
http://www.weather.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl’)
ndfd.add_method(‘NDFDgenByDay’)
puts ndfd.NDFDgenByDay(38.99, -77.99, ‘24 hourly’, ‘2004-04-27’, 3)

When I run the script I get the following error:

/usr/local/lib/ruby/1.8/soap/rpc/driver.rb:230:in `NDFDgenByDay’: wrong
number of arguments (5 for 0) (ArgumentError)
from weather.rb:6

I also tried to call the method like this:

puts ndfd.NDFDgenByDay(‘Latitude’ => 38.99, ‘Longitude’ => -77.99,
‘Format’ => ‘24 hourly’, ‘Start Date’ => ‘2004-04-27’, ‘Number of Days’
=> 3)

but got the same error

I just don’t get why the method seems to expect “O” arguments?

I did not, but I think maybe you should call add_method with 5
arguments. I have seen something like that Googling ‘SOAP add_method’.

Why don’t you try NDFD sample client in soap4r distribution? It seems
to work for me.
