JSP Tutorial

Java Server Pages (JSP) is a server-side programming technology that can create dynamic, platform-independent methods to build web applications. JSP can access the entire Java API series, including the JDBC API for accessing enterprise databases. This tutorial will teach you how to develop web applications using Java Server Pages through simple steps.

JSP, similar to PHP, ASP, ASP.NET, and other languages, is a server-side language.

JSP (Java Server Pages) is a web page technology standard jointly created by Sun Microsystems and many companies, which allows software developers to dynamically generate HTML, XML, or other format documents in response to client requests.

JSP technology is a scripting language based on Java, and the JSP web pages provide an interface for the entire server-side Java library unit to serve HTTP applications.

JSP file suffix name is *.jsp .

WEB applications developed with JSP can be used across platforms, and can run on both Linux and Windows.

First JSP Program

The first program for language learning beginners is usually to output 'Hello World', and the JSP code to output 'Hello World' is as follows:

Example

<html>
　　　　<head>
　　　　　　　　　　　<title>First JSP Program</title>
　　　　</head>
　　　　<body>
　　　　　　　　　　　<%
　　　　　　　　　　　　　　　　　　out.println("Hello　World！");
　　　　　　　　　　　%>
　　　　</body>
</html>

Test and see ‹/›

Output after running:

Hello　World!

JSP embeds Java code and specific dynamic content into static pages, achieving the dynamic generation of part of the content based on a static page template. JSP introduces XML tags called 'JSP actions' to call built-in functions. Additionally, JSP tag libraries can be created and used like standard HTML or XML tags. Tag libraries can enhance functionality and server performance and are not subject to cross-platform issues. JSP files are compiled by its compiler into more primitive Servlet code at runtime. The JSP compiler can compile JSP files into Servlets written in Java code, which are then compiled into executable binary machine code by the Java compiler, or they can be compiled directly into binary code.
