Introduction to jsp and jsp life cycle
Published on 30 Sep 2026
Explanation
JSP, or JavaServer Pages, is a server-side technology used to create dynamic web pages using HTML with Java-based server-side features.
Code:
<html>
<body>
<h1>Welcome to JSP</h1>
</body>
</html>
Explanation
A JSP page is translated into a servlet by the JSP container before it is executed.
Code:
JSP Page ↓ Translation ↓ Servlet Source ↓ Compilation ↓ Servlet Class ↓ Execution
Explanation
The JSP lifecycle includes translation, compilation, initialization, request processing, and destruction.
Code:
JSP ↓ Translation ↓ Compilation ↓ _jspInit() ↓ _jspService() ↓ _jspDestroy()
Explanation
The _jspService() method is generated by the JSP container and handles requests to the JSP page.
Code:
Browser | v JSP | v _jspService(request, response) | v HTML Response
Explanation
JSP is commonly used as the View layer in traditional Java MVC applications.
Code:
Browser ↓ Servlet Controller ↓ Service / Model ↓ Servlet ↓ JSP View ↓ Browser
