If you are a newcomer to JSP it is doubly important that you start out on the right foot and do not learn bad practices and habits at the outset. Why use old technology that's considered a bad practice?
It's sort of like saying "I want to learn how to design TVs -- teach me all about vacuum tubes."
Get yourself an up-to-date JSP reference that focuses on the JSTL and EL, and not on outdated Java scriptlets.
Eventually you may have to learn something about scriptlets in order to work on old legacy code, but they should not be what you set out learning first (if at all).
