Question

Difference between JSP1.2 and JSP2.0

Answer 1

See JSP 2.0 - The New Deal

To clarify, this article itemises in the first section the enhancements added to JSP 2.0.

Answer 2

Apart from the things mentioned in JSP 2.0 - The New Deal, an often overlooked new JSP 2.0 feature is JSP tag files which can be a pretty cool way to create reusable components with JSP. That can be small tags just doing one thing used in many different JSP pages (like e.g. formatting a currency styled in a special way) or it can be used for general template composition.
