I'm evaluating some of these technologies for one of my project. I need to use ECHO2 for the UI. And, I'm free to choose any technology for implementing my business services.
I read that Seam is more a glue between JSF and EJB 3.0. Right? Is is useful outside of this context? What other services of SEAM will be useful if I don't plan to use it with JSF.
At this point, it is quite difficult to integrate Seam with other web frameworks apart from JSF.
