Difference Between JSF, Servlet And JSP

Difference Between JSF, Servlet And JSP




At present, Java is used widely by programmers for developing a wide variety of software applications -desktop GUI applications, websites, web applications, and Android mobile apps. Java has been evolving consistently to simplify and accelerate development of custom applications based on varied business requirements. Java 8 supports widely used functional programming concepts like anonymous roles and lambda expressions.

At the same time, Java 9 helps developers to build and continue applications easily by writing modular programs. Also, a developer has option to choose from a wide range of Java-based technologies based on kind of application and project requirements. JavaServer Faces (JSF), Java ServerPages (JSP), and Java Servlets are used widely by Java programmers. But the technologies differ from each other in terms of design goal, functionality, and usage.

fleeting Overview of JavaServer Faces, Java ServerPages, and Java Servlet

JavaServer Faces (JSF)

JSF is a Java-based web framework. It simplifies web application development by allowing programmers to building part-based user interfaces (UIs). In addition to providing a standard of UI elements, JSF also allows developers to build custom UI elements by an application programming interface (API). Also, the developers can use JSF to connect the reusable UI elements seamlessly with various data supplies and server-side event handlers.

The programmers can take advantage of JSF to simplify web application development and maintenance by using reusable elements. They can already run the web framework on Java application server, and make it render UI elements according to targeted clients. JSF already makes it easier for developers to Implement custom UI elements, ease data move between various UI elements, and connect client-side code to server-side events handlers.

Java Servlet

Servlet is a Java-based technology that accelerates web application development by providing part-based modules. The developers can further use Java Servlet as a class to extend the web server and respond to various types of incoming requests. At the same time, the Java programmers can also use Servlet to build custom web applications based on varied business requirements by taking advantage of various Java APIs. They can already use Servlet to collect user input by web forms, present records retrieved from various data supplies, and generate web pages on the fly.

Many programmers use Java Servlet as a faster different to shared gateway interface (CGI). They also have option to create custom Java Servlets by the packages provided by Java EE – javax.servlet and javax.servlet.http. Java Servlet makes it easier for programmers to accomplish a number of web development responsibilities – reading implicit HTTP request or explicit data sent by web browsers, sending explicit data to the web browsers, send implicit HTTP responses to clients, and generating results by processing data.

JavaServer Pages (JSP)

JSP is a Java-based server-side programming which helps developers to create web applications that sustain dynamic content. While using JSP, the developers can access a wide range of Java APIs according to precise project needs. They can already use JSP tags to insert Java code into HTML pages without writing additional code. The JSP elements also act just like a user interface for the Java application. The programmers already have option to write JSP as text files, and integrate the text files smoothly with HTML, XML, and XHTML code.

While writing web applications in Java, the programmers can use JSP as a strong different to shared gateway interface (CGI). But the developers can use JSP tags to accomplish shared web development responsibilities by using JSP tags. They can already use JSP as dynamic elements in HTML, for creating dynamic web pages, and collecting user input by web forms. The JSP further permit developers to avail a wide range of enterprise Java APIs by leveraging Java Servlet API.

Comparing JavaServer Faces, Java ServerPages and Java Servlets

JSF, JSP and Servlet permit developers to write a variety of web applications in Java rapidly and efficiently. But they can use JSF as a web framework to simplify development of large and complicate web application development by implementing form-view-controller (MVC) programming paradigm. however, JSP can be used as a server-side technology to accomplish shared web development responsibilities by tags and accelerate template development with client-side technologies.

At the same time, Java Servlet can be used as pre-compiled Java programs to simplify development of web applications on the fly with dynamic content. The Java programmers has option to use JSP and Servlet interchangeably while developing web applications based on MVC pattern. Servlet is much faster than JSP. But JSP, unlike Servlet, allows Java developers to accomplish shared web development responsibilities without writing additional code. Also, JSP acts as the view in MVC, while Servlet acts as the controller in MVC. It is always advisable to use Servlets, instead of JSP when the web application is required to course of action or manipulate huge amount of data.

On the whole, developers can avail the features of JSP, JSF, and Servlet to build custom web applications rapidly based on varied business requirements. They must understand the Java based technologies differ from each other in terms of design, functionality, and usage. Hence, they must keep in mind the kind and requirements of individual web applications while comparing JSF, JSP and Servlet.
