Java on Server Side

Java on Server Side

       Java on the Server Side As useful as applets can be, they are just one half of the client/server equation. Not long after the initial release of Java, it became obvious that Java would also be useful on the server side. The result was the servlet. A servlet is a small program that executes on the server. Just as applets dynamically extend the functionality of a web browser, servlets dynamically extend the functionality of a web server. Thus, with the advent of the servlet, Java spanned both sides of the client/server connection.

In simple word

Java on Server Side

                 Java is a server-side programming language that’s widely known, popular for enterprise-level applications, and ideal for high-traffic sites that need room to grow. It’s also a core language of Google’s Android mobile application development, which brought it back onto developers’ radars in a big way. But, Java is much more than just a language—it’s the sum of many tools, collectively known as The Java Platform. This robust, open-source development environment includes libraries, frameworks, APIs, the Java Runtime Environment, Java plug-ins, and Java’s Virtual Machine (JVM). In short, developers have everything they need at their fingertips to build Java web systems and applications.

                                 Servlets are used to create dynamically generated content that is then served to the client. For example, an online store might use a servlet to look up the price for an item in a database. The price information is then used to dynamically generate a web page that is sent to the browser. Although dynamically generated content is available through mechanisms such as CGI (Common Gateway Interface), the servlet offers several advantages, including increased performance.

            Because servlets (like all Java programs) are compiled into bytecode and executed by the JVM, they are highly portable. Thus, the same servlet can be used in a variety of different server environments.



The only requirements are that the server support the JVM and a servlet container.
