SOAP request parameters


I have a problem with Ruby SOAP client. Basically, I create new client
instance via, then I use add_method(‘method’,
‘param1’, ‘param2’) and then try to call the method -
soap.method(‘value1’, ‘value2’). The problem is that instead of the
values, parameter names (“param1” and “param2”) are sent to the
server… Can anybody please tell me what am I doing wrong?
