A new project requires that I use a web service from a batch client program run every few minutes to retrieve a list of items, and use the same web service from another program called on an ad hoc basis to update items as required. Note: this isn't my web service, it's one provided by an external company. Our environment is AIX.
Is there anything that I can use that's as simple as the Netexpress example using the Microsoft SOAP toolkit  ? And is there a guide to client SOAP programs for dummies anywhere?
