I have a doubt about which framework must i choose. We are working under Novell Portal Service 1.5, Servlets (Gadgets) + XSL, and we need to developer an application Web without this framework. I had thougth that i could use a framework like Apache Cocoon, because it works with XSL too and migration code will be easier. How would you see this framework? Or maybe, you would choose another open framework near to NPS 1.5. Thanks in advance and greetings from Spain.
