Hi NaHi,
Sometimes the soap message contains the empty soap:body,
and the request (or response) argument may be empty.
Initially I added the document method in the following way:
server.
add_document_method('listProducts',
'http://warehouse.acme.com/ws/listProducts',
nil, # emtpy request
XSD::QName.new('http://warehouse.acme.com/ws',
'listProductsResult'))
This then resulted in following :
/usr/lib/ruby/1.8/soap/rpc/element.rb:166:in `create_doc_param_def': undefined m
ethod `each' for nil:NilClass (NoMethodError)
from /usr/lib/ruby/1.8/soap/rpc/driver.rb:148:in `add_document_method'
from WarehouseNoWsdlClient.rb:9
The quick fix is to do :
server.
add_document_method('listProducts',
'http://warehouse.acme.com/ws/listProducts',
[], # emtpy request
XSD::QName.new('http://warehouse.acme.com/ws',
'listProductsResult'))
But perhaps a slightly more defensive code could be used in soap/rpc/driver.rb:

21:53:24.358155600 -0700
