I've posted my thoughts on Seam 1.0 to my Virtuas blog. What are your thoughts?
It's great to see the release of Seam 1.0. Seam is similar to many full-stack frameworks like Rails, Rife and AppFuse in that it gives you all the pieces you'll need to build a kick-ass web application.
I've blogged my thoughts on Seam before, so there's no need to do that again. I like the idea, especially the lack of interfaces and the 3-files-for-each page idea. However, I don't know that this concept will fly with Java developers. I agree there's a need to simplify, but many of us are mesmerized by the de-coupling that Spring gives us. So now we're programming to interfaces, and every-so-often swapping implementations. I don't know that we can switch to this simpler model. And then there's the "EJB" thing. I think there will be a fair amount of developers that don't use EJB3 simply because it has the "EJB" name. The best thing the EJB Expert Group could have done for EJB3 would be to give it a new name.
The other thing I worry about with Seam is that it wasn't developed from an existing application. AFAIK, it didn't get extracted from a real-world application that had all the problems that Seam solves. I know that Gavin is a smart guy, and he's probably seen these problems in the real world, but there's nothing like developing a real-world application with a technology - and then extracting the framework from that.
In reality, I'm probably jealous. Seam has some really cool features, JBoss has done a great job of marketing it, and it seems to be a really cool way to develop applications. If I'm going to make AppFuse a direct competitor to Seam, it's gonna be quite the uphill battle.
