Hi, i’m trying to generate objects for my wsdl and wsdl2ruby comes with  
error:

F, [2006-01-30T15:16:20.082000 #3520] FATAL – app: Detected an  
exception. Stopping … undefined method `namespace’ for nil:NilClass  
(NoMethodError)

any solution for this?

comand line:  
ruby wsdl2ruby.rb --wsdl mywsdl.wsdl --type client --force

wsdl is below:

It’s the bug of soap4r. I fixed it at the subversion repository though  
I’m afraid of seeing how wsdl2ruby.rb can handle .NET DataSet. Would
