Obviously, you all want to try out the new WS-Security support that was added to Spring-WS in release 1.0 M1. However, security is no simple beast, and WS-Security is not different at that.
So I've started working on a chapter in the reference documentation which tries to explain WS-Security, and how to use it within Spring-WS. It only covers plain text passwords now, but I will try and fill in more topics later this week.
I've uploaded new versions of the reference docs, which can be found here: HTML version, PDF version. It's chapter four.
