I'm trying to write a client that fetches a weather forecast using soap4R.

require 'soap/wsdlDriver'  
weather = SOAP::WSDLDriverFactory.new(  
&nbsp;&nbsp;&nbsp;"[http://www.nws.noaa.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl](http://www.nws.noaa.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl)"  
).create\_driver

This works ok and weather is created.

My problem is how do I enter the parameters for the function call  
the parameters are:  
\<part name="latitude" type="xsd:decimal" /\>  
&nbsp;&nbsp;\<part name="longitude" type="xsd:decimal" /\>  
&nbsp;&nbsp;\<part name="product" type="typens:productType" /\>  
&nbsp;&nbsp;\<part name="startTime" type="xsd:dateTime" /\>  
&nbsp;&nbsp;\<part name="endTime" type="xsd:dateTime" /\>  
&nbsp;&nbsp;&nbsp;\<part name="weatherParameters" type="typens:weatherParametersType" /\>

&nbsp;&nbsp;&nbsp;The weatherParameters variable is an array of booleans eg. maxt, mint,  
others

sReceived=NDFDgen("What goes here"........)

Any help would be appreciated.

I started making a client for that service in Python. The only tricky part is the array of booleans. If my thinking is correct, a hashmap will work there. So do something like this.

....  
lattitude = 15.0  
longitude = 15.0  
product = "glance"  
startTime = "The time format they use, I forget"  
endTime = "The same"  
weatherParameters = { 'maxt' =\> true, 'mint' =\> false, .... }

Response = NDFDgen( lattitude, longitude, product, startTime, endTime, weatherParameters )

If my thinking is correct this will work. If it doesn't, then the hashmap might not be correct. You may have to manually create a SOAP structure for the weather parameters. Let me know how it goes. The real trouble you will have is writing a parser for the response, it is in a very ugly format.

Thanks for the help. I've tried this method and others but I keep getting  
this message  
Unknown element {[http://www.w3.org/2001/XMLSchema](http://www.w3.org/2001/XMLSchema)}simpleType.  
Don't know where that error is generated. Tried grepping for 'Unknown' and  
'Unknown element' but can't find any files where the phrase 'Unknown  
element appears.

After this message I get this  
c:/ruby/lib/ruby/site\_ruby/1.8/soap/mapping/wsdlRegistry.rb:73:in  
`obj2soap': Cannot map String to SOAP/OM. (SOAP::Mapping::MappingError)  
I'm sure this error is directly related to the Unknown element message  
because this error is occuring when it obj2soap is processing 'product'  
which is defined by NOAA's wsdl as xsd:simpleType.  
I have no clue what is wrong here. the w2.rog/2001/XMLSchema defines  
simpleType. Does soap4r have a problem or does the NOAA wsdl have a  
problem?

Try wsdl2ruby.rb which is included in soap4r/1.5.2.

0% wsdl2ruby.rb --wsdl ndfdXML.wsdl --classdef --force

&nbsp;&nbsp;&nbsp;attr\_accessor :maxt  
&nbsp;&nbsp;&nbsp;[snip]

end

# [http://www.nws.noaa.gov/forecasts/xml/DWMLgen/schema/ndfdXML.xsd](http://www.nws.noaa.gov/forecasts/xml/DWMLgen/schema/ndfdXML.xsd)  
module ProductType  
&nbsp;&nbsp;&nbsp;Glance = "glance"  
&nbsp;&nbsp;&nbsp;TimeSeries = "time-series"  
end  
0%

"moduel ProductType" might not be dumped under soap4r/1.5.2. Once you install ruby's current CVS (or snapshot for 1.8.2), it will be dumped. So, it should work.

0% ruby -rsoap/wsdlDriver -rdefault -e '  
now = Time.now  
drv = SOAP::WSDLDriverFactory.new("[http://www.nws.noaa.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl&quot;\](http://www.nws.noaa.gov/forecasts/xml/DWMLgen/wsdl/ndfdXML.wsdl&quot;%5C)).create\_driver  
drv.NDFDgen(123, 456, ProductType::Glance, now - 60, now, WeatherParametersType.new)  
'

...though I don't know what is the meaning of each parameter.

Just ignore "simpleType" warning untill 1.8.2 to be released. Sorry for the inconvenience.

Thanks, I'll give this a try. I'm running Windows XP and ruby 1.81. So  
I'll double check on the module.  
By the way, I have been getting this information via a simple form post to a  
web server runing a php script that ships the  
xml out in the same form. I don't know how long that service will run, so I  
thought I'd give SOAP a try. If NOAA continues the  
web service, it will probably be only SOAP.

Thanks again.
