What is the difference between .jsp and .jspf files?

Answer 1

A JSP page is a text document that contains two types of text: static data, which can be expressed in any text-based format and JSP elements, which construct dynamic content. The recommended file extension for the source file of a JSP page is .JSP (which is what most people see). The page can be composed of a top file that includes other files that contain either a complete JSP page or a fragment of a JSP page. The recommended extension for the source file of a fragment of a JSP page is .JSPF.
