JBoss guys - as I understand mostly Gavin King and Thomas Heute have written an Introduction to JBoss Seam. From a first glance at it this is a real neat document.
It looks like JBoss Seam has a good future to become a de facto standard for webapp development.
The funny part about JBoss Seam is that with it, there will be no more seamless development and integration. Nice marketing trick. Hey, who hat the idea to this name?
