Difference Between JSF and JSP

Website was an important achievement in the world of computing. There are different kinds of websites like personal, governmental, business, corporate, organizations, etc. They are dedicated to one purpose.

They are linked by many other websites with the help of hyperlinks. A static website is something that has a lot of web pages and information is stored on them in the format sent by the Client browser.

Dynamic websites are something that changes automatically every day and customizes things. JSF and JSP are also a part of websites. They serve different purposes.


The main difference between JSF and JSP is that JSF stands for Java Server Faces and JSF stands for Java Server Pages. JSF is a framework that allows developers to develop their user-interface application from the side of the server. JSP is a technology that is used by developers to develop dynamic websites and webpages using XML, HTML etc. JSP is best suited for developing small applications. While when it comes to JSF can be used to develop larger applications. JSP is a very old technology but is developed fully. While JSF is a new framework and is still in its developing phase.


JSF stands for Java Server Faces. It uses Java technology. It is primarily used for building the user interface for web applications. It can also be used as a component-based system. It simplifies the data integration.

It is best suited for the larger project work. It describes various sets of components like API i.e. application Programming Interface and UI components.

It also gives the facility to connect with UI, reuse it, extend it or target the customer. It simplifies the transfer of the data among UI.

JSP stands for Java Server Pages. It helps software developers to make dynamic web pages with the help of SOAP, XML, HTML and other types of documents. JSP is very similar to PHP and ASP, but it uses Java Programming.

JSP can also be viewed as Java servlets. Because they are converted into one in their run-time. So every JSP is a servlet. It’s cached and reused until the original JSP is modified.

Either JSP can work independently or become a part of server-side controller design.

What is JSF?

JSF is a framework that is why it is used widely in the web industry. It can be said as the component-driven model that is run by UI. It forms a part of Java Platforms as it was formalised by Java Community Process.

It uses the MVC framework which makes JSF simplify the UI components in one page. Java specification request proposed the technology in developing the package known as Java server pages in 2001.

Talking about the recent developments in JSF, Facelets was developed and was incorporated in JSF 2.0 version.

The function of Facelets is to provide tag creation using XML instead of Java codes.

The latest JSF has new features that support handling Javascript, images, CSS, can separate them into JAR files, adding support for separate development, staging, events, and production modes etc.

Facelets take up the requests, then load the given template, makes a component tree, processes it and then waits for the response from the client.

All the interests of UI components are saved at the end of every request called stateserving.

It has multiple features that are not in JSP. Like it is one of the largest presentable type of application. It can handle large projects easily.

Ajax which is one of the popular apps in the field of UI designing can be run, handled and managed by JSF only. Because of its integration, JSF goes so well with it.

What is JSP?

JSP was developed by Eclipse Foundation, 22 years ago. If we have to run JSP then we would need a web server that is compatible with a servlet container, like Apache Tomcat /Jetty.

It was released in 1999 by Sun microsystems. It runs on Java Programming language and is very similar to PHP and ASP. JSP was mainly built for creating dynamic web pages by the software developers.

It works very well with small applications. But in large applications, a certain framework and component-based module and interface are required that JSP doesn’t have. JSP is a request based servlets.

It means that it will run when a request is sent to the client. It can be used independently. But JSP is mostly used as a component of MVC design. A model can be JavaBeans and the controller can be JavaServelet.

JSP is suited for the service related to purpose, unlike JSF. The working of JSP is very different from JSF. In JSP, one component doesn’t affect the other. So if there is any error, it will not be any problem.

New views can also be created in JSP without having to write the model.

JSP is more flexible. However, in terms of maintaining the structure of the web applications, it becomes tough. JSP has a core technology. So various kinds of developers will be developing different components.

It becomes messy when all of the components are integrated.

Main Differences Between JSF and JSP

  1. Extension used for JSF is .jsf. Extension used for JSP is .jsp, .jspx, .jspf.
  2. JSF is a framework consisting of a faces servlet controller with backing beans. JSP is accessed by webpages like HTML, XML etc.
  3. JSF tagging attributes are dynamic and can automatically map properties, value expressions on the UI interface. In JSP, the tag needs to be declared in TLD file.
  4. JSF integrates with rich face support. While JSP doesn’t.
  5. Features of JSF includes managed beans, a template-based component system, and two XML based tag libraries. The feature of JSP is to compile a java bytecode to function properly.


Both JSF and JSP are based on Java Programming Language. Both are meant to be used for web-based applications. But it can be said JSF is better than JSP. JSP is the past and JSF is the future of web applications.

Because JSP is an older technology and has been developed fully. While JSF is new and is still in its developing phase. JSP is the main technology. But JSF can be divided into six phases for development.

Integration and other features make JSF seamless and hassle-free without any bugs or errors. It can be said that a beginner should learn JSP first to learn and move up to JSF.
