At the risk of stealing someone's thunder...It looks like Spring Web Flow 1.0 is final!
As I write this, it hasn't been officially announced on any of the Spring mailing lists or on the Spring home page. But I noticed the 1.0 release mysteriously disappearing from JIRA. When I visited the Spring Web Flow home page, I see that it was released yesterday (or very late last night). I've already picked up my copy from here.
I've found Spring Web Flow to be a great way to develop conversational flow-driven web applications. The thing that most surprised me about SWF is that I was able to write a fairly complex flow-driven application while writing very flow-specific code. I was able to leverage my application's existing service layer in many cases and only had to write flow-specific action code when I needed the flow to do something that my services didn't already provide.
Congratulations to the Spring Web Flow team on this monumental release!
