Well that is the title of the presentation I just gave at the NL-JUG 2007 conference. The presentation was about the Spring Web Flow solution we created to secure flows. The presentation can be found and the conference website. The code is available in the JIRA under issue SWF-93 but for your convenience also available for download (press the link on the bottom of this post).
The presentation went well, there were some nice questions and a little bit of discussion. So my conclusion was that it was a nice presentation. I will blog about using this security solutions shortly. However for now I have a conference to attend.
