Agreed. I didn't mean for my comment to imply the samples or Spring-WS were too complex, just that it was difficult for me to, in essence, learn webservices via looking at the code. Its hard to know what's the "right" way to do something, and with things like security, ignorance can be dangerous. Basically, I was looking for a developer-level coverage of WS tech. For now, I'll just keep pushing through the refs.
Overall, SOAP, WSDL, WS-Security are not simple technologies, but I try to make it as simple as possible without loosing any of the expressive power.
