Properties files are usually used for configuration (like ini or rc files).
They store a list of name/value pairs.

See:
http://java.sun.com/j2se/1.4.2/docs/api/java/util/Properties.html

'.jspf' is an extension that you give to JSP fragment files, intended to be used as include files. The 'F' tells compilers that these files are not intended to be compiled as standalone JSPs.

Siva,
Ben meant the "F" as in the last letter of .jspf, or fragment.

Normally, when you have a standalone JSP, you can type its name into a web browser and get some output. A JSP fragment is intended to be part of a JSP. So if you were to type its name into a web browser, you wouldn't expect to get anything meaninful, or even an error message.

If you have a JSP that only gets included in other JSPs, call it a JSPF. This is useful for common page elements, such as headers and footers.
