Caught the last half of U-Camp at Sakai — mostly a presentation on RSF, from a designer’s perspective. There are pieces of RSF that do look attractive — plain (X)HTML templates, Spring integration, etc. I still wonder if the world needs yet another component framework — especially one that’s essentially proprietary to Sakai/Higher Education. Tapestry? Or, does it make more sense from a team perspective to pick something like plain old JSP that people are likely to have seen or use outside of Sakai?
