Hello,

First the code of my little script. I am trying to get some infromation  
from other service using SOAP.

The code:

require ‘soap/wsdlDriver’  
wsdl = “[http://some.service.com?wsdl](http://some.service.com?wsdl)”  
service = SOAP::WSDLDriverFactory.new(wsdl).create\_rpc\_driver  
service.doSomeMethod(1,1,1)

* * *

The “doSomeMethod” reqiuires 3 parameters but the name of the parameters  
contains dash “-” char. And I get following error executing  
“doSomeMethod”:

ERROR: NameError: `@some-varname’ is not allowed as an instance variable  
name

Can anyone help me solving the problem ? I tried to find some solution  
but I lost my hope 🙂

Thank you in advance,  
Lukasz

Hi,

sounds like you might have found a bug in the soap library.

as a work around, is there a “document” version of the soap call  
available?

something like:

service.doSomeMethod({“some-varname” =\> “value”, “var2” =\> “value”})

nope. unfortunately it gives wrong number of arguments (1 for 3)  
(ArgumentError)

too bad ☹
