Should I learn Java before JSP?

Question

I have the opportunity for a new job in which I'd be moving from PHP to JSP. I've done a little java in the past but am just wondering if I should revise my java knowledge before attempting to learn JSP?

Answer 1

If you are going to write business logic too (not only views in JSP), then knowing the Java language is required.

On the other hand, if somebody else codes all the business logic for you, and all you are left with is objects injected into your JSP, you might get away with just using JSTL alone to control the formatting of your views. (i.e, no scriptlets in your views)
