I have read in FAQs for SCWCD regarding version 5 of the exam:
Quote from Bert on April 2006: "The [1.4] exam will be available and "current" for a long time. There is no plan to update the SCWCD exam, I would guess that the EARLIEST that the SCWCD will be updated is at least a year away. At that point, the current exam will still be available for AT LEAST another year past that."
And its almost one and a half year now.. Any updates on when Sun is going to release version 5? If not now, then how beneficial will it be to go for 1.4?
I think JSF should be outside the scope of the exam, however "political considerations" might drive it into the exam. There is always a debate as to what should be included, and how to keep to the essentials. I suspect many, many people will use JSP/Servlets without using JSF and (for me) that would be a reason not to include it, and keep the exam to the core essentials.
