Hello everybody, I’m using the following to get a driver to call to some functions on a remote soap described by wsdl: require ‘soap/wsdlDriver’ wsdl = “mywsdluri” client = SOAP::WSDLDriverFactory.new(wsdl).create\_rpc\_driver Then I can easy call soap methods with client.method\_name, but I’m not able to figure out if I could get a simple list of paramaters those methods requires. I’ve found this ticket [1], with dump\_method\_signature that seems to be something like what I’m searching for, but I could’t understand how to use it. Some ideas? Thanks in advance Marco S.

Can’t you just look in the wsdl? When I used soap4r I did something like: params = {:param1 =\> ‘some\_value’, :param2 =\> 42}; response = driver.my\_method params I took :param1 and :param2 names directly from the wsdl method definition. Otherwise, you can use wsdl2ruby… Hope it helps ---

Have you tried sending dump\_method\_signatures to a WSDLDriverFactory object? Right now I’m on a windows machine (with ruby 1.8.6) and WSDLDriverFactory doesn’t have that method, so I can’t try. It should include WSDL:🧼:ClassDefCreatorSupport and so you should be able to call dump\_method\_signatures. Otherwise, you could try to iterate on the services/ports of the wsdl attribute of a factory object, just like dump\_method\_signature does. I am no expert, so don’t take my suggestions too seriously 🙂 Bye ---

For complex ones, it only show type’s name. ☹ ---
