A JSP Web Hosting Review is a report based on research analysis and comparative assessment to indicate how the utilization of Java Server Page Technology to maintain the smooth operations of a dynamic web site is either preferable or not, over other scripting technologies. JSP technology provides for the speedy development of web based applications that can remain server and platform independent. It permits web developers to easily maintain data intensive sites that are characterized by dynamic fluidity. The user interface is quarantined from content generation, leaving the developer to edit the interface page without affecting the under flowing fluidity of dynamic content. Developers are afforded advantages by using JSP technology. Developers and designers familiar with HTML are able to incorporate JSP technology, without having to learn the Java language, and without having to write Java scriptlets. Scriptlets are only still supported to provide backward compatibility and are no longer required to produce dynamic content. The facility to extend the JSP language with elementary “tag handlers” proliferates the amount of “tag libraries”, that are pluggable and reusable, and consequently creates a significant easing up, on the efforts to design and develop powerful web applications, that would otherwise require pages and pages of code to be written. The Java Server Pages Standard Tag Library(JSTL), expression language has been integrated into the technology and upgraded to provide support to functions. Scriptlet expressions have now been replaced with the expression language. So the pages can be written and maintained much easier now.
A JSP Web hosting review would be incomplete without highlighting the importance of the technology. It fashions the logic that produces the content for the pages by employing tags similar to the XML tags. While the application logic is housed in server based resources, for instance – JavaBeans component architecture, the web page can access it with these tags. Formatting tags - either HTML or XML - are directed back to the response page. In the creation of this segregated design, where the page logic is capsuled apart from the design and display of the page, while simultaneously driving a reusable component based design, the JSP technology makes the business of building and designing web based applications, a much more accelerated and simplified affair. Being an extension of the Java Servlet Technology, it employs these platform independent, server side modules, to smoothly slide into a web server framework, and extend its capabilities with only marginal overheads, maintenance and backup support. Servlets do not require platform specific considerations or modifications, like other scripting languages. These application components are downloaded to a specific section, as and when the utilizing system requires them. This powerful combination of JSP technology and servlets has distinguished itself as a preferred alternative to competing web programming applications. The salient features it offers are, platform independence, enhanced performance, capsulation of logic apart from display, administrative simplicity, extensibility into the enterprise and ease of use. JSP pages feature the “Write Once, Run Anywhere” advantages of Java Technology, which is a primary component of the Java 2 Platform, Enterprise Edition, which is Sun’s highly scalable architecture for enterprise applications.
