I am new to Ruby and am evaluating it for a project that would replace  
and extend existing Perl code. I am using wsdl2ruby to generate a  
client stub with associated classes for a web service. Most of the  
basic calls more fine but the more complex method calls that take  
parameter “anyType” do not work so well. It appears that the type is  
not getting set in the SOAP message generated by ruby. However, the  
perl code does allow me to set the type (manually by calling  
SOAP::Data → type using SOAP::Lite). Below is the relevant code and  
generated messages:

Unfortunately, Driver#generate\_explicit\_type = true does not work for  
literal service. I’ll look into how I can implement it.

No easy way for now.

req = SOAP::SOAPElement.new(XSD::QName.new(“urn:example.com”, “req”))  
value1 = SOAP::SOAPElement.new(“value1”, “1”)  
value1.extraattr[“xsi:type”] = “xsd:int”  
req.add(value1)  
driver.method\_call(req)
