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}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?
