JSP (Java Server Pages) is a technology that uses scripting elements like scriptlets, expressions, declarations, comments and directives to embed Java code within an HTML page. This allows the page to be dynamically generated each time a client requests it. Key elements include scripting elements for Java code, comments, and directives to control page caching, error pages and include files.
