John Udell writes about debugging SOAP, including using Mindreef’s SOAP Scope. SOAP Scope is truly wicked, and worth more than the $99 that they are charging if free tools like Simon Fell’s TCPTrace aren’t enough for you. I think changing views from looking at the raw XML going over the wire to pseudocode was truly cool, and can really help visualize what’s going over the wire. I’ve said it before, but their presentation at Web Services DevCon East was an eye opener.
