Hi Leonardo, thanks for your explanations. I worried that I have to refactor my c:imports or jsp:includes for JSF. Unfortunately there are some more than in my example. :) But I hope that the benefit using JSF will compensate the effort.
@John: Thanks for you suggestions. We have some more projects running which may use another technology.

Unfortunately that cannot be done, because both are different view declaration languages, with its own rules. The following text on JSF 2.0 spec section 10.1.1 says this: "... Facelets was the first non-JSP view declaration language designed for JavaServer Faces. As such, Facelets was able to provide a simpler and more powerful programming model to JSF developers than that provided by JSP, largely by leveraging JSF as much as possible without carrying backwards compatibility with JSP ..." In few words, with JSF 2, most of the problems related to JSF 1 + JSP were solved. The preferred way to solve your problem is convert your old jsp pages into .xhtml pages that can be loaded by facelets engine. The idea is just replace all your c:import or jsp:directive.include into facelets ui:include. Note it is also possible to have facelets and jsp pages on the same app, but you can't mix them on the same view. Other option is just create a duplicate of those jsp pages for facelets and later use them on your new views. @John: it could be good to know if your reasons to object JSF. In my understanding JSF 2 solved many of the problems, and it have some very useful features. Maybe if some idea is enough useful, myfaces community can push to include it on next JSF 2.2 spec. Suggestions, critics and tomatoes are most welcome ;-). That's how innovation works, right? regards, Leonardo Uribe 2011/9/7 Carlson, John W. <carlso...@llnl.gov>: > Get a grip. JSF sucks.
