Sanjiv has some interesting thoughts on the future direction of AppFuse. To summarize: take on Seam head-to-head, but use Spring instead. Get rid of all the other frameworks except for JSF, Spring and Hibernate. Furthermore, focus on making Web 2.0 applications easy to create and use.
I like Sanjiv's ideas, but I'm not so hot on ditching all the other web frameworks in favor of JSF. I'm still not convinced it's the best solution for Java web development. The idea behind JSF is great, but the implementation has warts. Maybe that'll be fixed with JSF 1.2, but it will likely be quite a few months before MyFaces supports it. Yeah, I know there's the RI, but it is an RI and you remember the 1.1 version don't you?
I'd hate to give up WebWork support because I've used it on a couple of projects and really like it. Ditching Spring MVC would likely be a mistake as well since it's the most popular web framework among AppFuse users today. While I love what Tapestry brings to the table, it is harder (for the newbie) than JSF. Also, it seems to be the least-used web framework in AppFuse, which means I'm doing a lot of maintenance for no reason. AppFuse 2.0 will definitely make things simpler (JDK 5, Maven 2, standard directory layout, better IDE integration), but it will still be difficult to support 5 web frameworks and 2 persistence frameworks.
What do you think about Sanjiv's proposal? It sounds good to me. However, I'd rather see different lead developers for each framework and continue to support them all - except for Struts of course.
