JSPs are a (much older) standard for generating web pages from templates - these can be used as the View in a JSF application, but also separately from JSF. Facelets are an alternative view technology based on pure XML templates (no scriptlets) which was introduced with Version 2 of the JSF standard. They can only be used in a JSF application.
