    As those involved in SOA technologies will know web services and integration is a fairly dry subject. Typically the integrated systems and services sit behind a facade of other systems or web and desktop based applications. How then do you interest business users of the power of your solution? How do you quickly build or mock up an application that will interact with your back end services? We had just such a problem and needed a way to keep senior technical staff and business users awake during a presentation. We searched for something suitable - we knew that editing XML in SOAP UI would not work well - in the end we created our own demonstration framework - this is the result.
