JSP creates a document (such as HTML) from template text and scripting actions. Template text is returned verbatim to the requesting client, and actions are used to fill in dynamic values and do things conditionallly.

JSP compilation causes the compilation of JSP files before they are first accessed on a live server.

JSP EL
