JSP Tutorial

Sun Microsystems’ JSP (Java Server Page) technology, is an object-oriented programming language based on Java. JSP is used to develop interactive and dynamic web sites and create database driven web applications. JSP simplifies the development process, allowing programmers to input Java code directly into the HTML file or JSP file. JSP is a multi-platform, independent and portable language that complies with the Java feature of ‘write once, run anywhere’. JSP is efficient, reusable, robust and includes a clear division between presentation and implementation layers on the client and server sides, respectively. JSP provides programmers the capability to create code independently of the existing work of Java developers. Java Server Pages separates the content of the web page from the appearance of the web page.

Online training is provided on JSP along with relevant information for developers and programmers such as how to use JSP Tags, Directives, organization of JSP Architecture, Session Objects, Request Objects and working with JSP Sessions.
