The Struts 2.0 development has been closed down. Struts Shale will be a new codebase for web development. No surprise that Struts would move to closer JSF integration, but dropping the entire codebase is a bit surprising. I guess Shale will be a fresh start, probably in some ways resembling the old Struts but building on experiences and improving. I think they have done a great job with Struts already (it’s been a long time since it’s conception, and it has of course suffered from some of the “old” ideas incorporated from the start), and will be looking forward to a new excellent product from Apache.
