Java Tutorial - Java Script :
The last subject to be explored is one of the most exciting and dynamic areas in Java: the use of a web server as a platform for application development. The Java language has moved beyond applications that run on your computer and applets that run on a web page. Servlets, web applications run by a server over the Internet and presented by a web browser, employ Java with all the features of the language. Using servlets, you can collect input from users through web page forms, present records from a database or another source, and create web pages dynamically. This approach can be enhanced by Java Server Pages (JSP), a way to create web pages that mix static Hypertext Markup Language (HTML) with the output of servlets and Java expressions. JSP enables nonprogrammers to work on websites developed with Java. Today you learn about each of the following topics:
· How servlets differ from applications and applets
· How to run servlets as part of the Apache web server and other servers
· How to receive data from a web page form
· How to store and retrieve cookies
· How to use servlets to dynamically generate web content
· How to develop web applications using JSP
· How to use Java variables, expressions, and statements on a page
