The Advantages of JSP

Java Server Pages or JSPs, is the extended version of Java servlet technology. It combines the incorporation of the Java code and HTML for use in one single file.

JSP is in vogue today, amongst all Java programmers, who create some of the most complex applications using this technology. Given below are some of the major benefits that JSP gives its users.

Knowledge of Java is not a necessity

You do not need to learn Java, if you want to use JSP. You can use JSP technology without having any knowledge of writing Java scriplets. Gone are the days when these scriplets were used to create dynamic contents; however they are still used to support the backward mobility of applications.

Extension of the language is easily achieved

Simple tag handlers can be used to extend the JSP language by designers and various Java tag library developers. These use a tag extension system called API, which is cleaner, simpler and can be utilized in a better way.

This has also resulted in the increasing availability of reusable tag libraries, which in turn has made the job of programmers easier by reducing the amount of coding required to develop complex and powerful applications for the web.

Its pages are easy to write and easy to maintain

JSP is inherently easy to use, develop, support, and maintain. JSP technology has now integrated the JavaServer Pages Standard Tag Library or JSTL within its fold and has also upgraded its existing functions to support the library.

This means that scriptlet expressions are no longer a necessity and the expression language can be used instead.

Great speed and scalability

The compilation of JSP pages into Java servlets takes place the first time they are called. Moreover, they are also loaded into the memory the first time itself, and then made executable for all the succeeding calls. This gives them alacrity and scalability.

Platform independence

JSP technology can be used on all platforms, without hassles. Moreover, all its components can also run on all web servers and servers enabled for web-based applications. Moreover, JSP pages are accessible from any web servers.

Configured for reusability

All components of JSP can be reused across platforms. These components include custom JSP tags, JavaBeans, and Enterprise JavaBeans. Both Microsoft Windows and UNIX platforms can be served by Enterprise JavaBean components, which access legacy databases.

The tag extension capability of the JSP technology also offers developers an interface resembling the XML interface. This allows page designers to share the packaged functionality through the length and breadth of the enterprise.

Stability and reliability

If you use JSP technology, your system won’t be susceptible to crashes. Moreover, memory management is a significant advantage of using JSP. It protects against memory leaks and also enables the faster deployment of applications.

Easy to maintain

Applications made from the use of JSP technology are easier to maintain in the long run. As the Java language has a specific structure, it’s easier to manage, and maintain, many modular applications.

Moreover, owing to its cross-platform architecture, the various platforms, web server, and various other components can be easily upgraded.

These essential benefits are the reason why JSP technology is so popular. You will realize this fact for yourself, once you work on JSP.
