JSP

JavaServer Pages (JSP) is a technology that helps software developers create dynamically generated web pages based on HTML, XML, or other document types. Released in 1999 by Sun Microsystems, JSP is similar to PHP and ASP, but uses the Java programming language.

JSP pages are compiled into Java servlets and run on a Java application server. A JSP page consists of HTML code, with embedded JSP tags that invoke built-in or custom actions. JSP tags can be used for a variety of purposes, such as retrieving data from a database or controlling the flow of a program.

A JSP page is compiled into a servlet by a JSP engine, which is then executed by a Java application server. JSP pages are typically used to create HTML or XML output, but can also be used to create other types of output, such as PDF or Excel files.

JSP pages can be created in any text editor, but most developers use an IDE that supports JSP development, such as Eclipse or NetBeans. To deploy a JSP page, it must be placed in a directory on the application server that is accessible to the JSP engine.
