Currently, Java is widely used by programmers to develop a variety of software applications – desktop GUI applications, websites, web applications, and Android mobile apps. Java is constantly evolving to simplify and accelerate the development of custom applications based on various business needs. Java 8 supports widely used functional programming concepts such as anonymous functions and lambda expressions.
Also, Java 9 helps developers easily build and maintain applications by writing modular programs. Also, a developer has the option to choose from a wide range of Java-based technologies depending on the type of application and project requirements. JavaServer Faces (JSF), Java ServerPages (JSP), and Java Servlets are widely used by Java programmers. But the technologies differ from each other in terms of design goals, functionality and use.
Overview of JavaServer Faces, Java ServerPages, and Java Servlet
Java Server Faces (JSF)
JSF is a Java-based web framework. It simplifies web application development by allowing programmers to create component-based user interfaces (UIs). In addition to providing a standard for UI components, JSF also allows developers to create custom UI components through an application programming interface (API). In addition, developers can use JSF to seamlessly connect reusable UI components with various data sources and server-side event handlers.
Programmers can take advantage of JSF to simplify web application development and maintenance by using reusable components. They can also run web frameworks on Java application servers, and render UI components according to it’s target customers. JSF makes it easy for developers to implement custom UI components, facilitates data transfer between different UI components, and connects client-side code to server-side event handlers.
Servlet is a Java-based technology that accelerates web application development by providing component-based modules. Developers can use Java servlets as a class to extend web servers and respond to different types of incoming requests. At the same time, Java programmers can use servlets to build custom web applications based on different business needs by taking advantage of various Java APIs. They can also use servlets to collect user input via web forms, render records retrieved from various data sources, and generate web pages on the fly.
Many programmers use Java Servlet as a faster alternative to Common Gateway Interface (CGI). They also have the option of creating custom Java servlets through the packages provided by Java EE – javax.servlet and javax.servlet.http. Java Servlets make it easy for programmers to accomplish many web development tasks – reading implicit HTTP requests or explicit data sent by the web browser, sending explicit data to the web browser, sending implicit HTTP responses to the client, and processing the data as a result. To create.
Java Server Pages (JSP)
JSP is a Java-based server-side programming tool that helps developers build web applications that support dynamic content. When using JSPs, developers can access a wide range of Java APIs according to specific project requirements. They can also use JSP tags to insert Java code into HTML pages without writing additional code. JSP components also act like a user interface for a Java application. Programmers also have the option of writing JSPs as text files and easily integrating text files with HTML, XML and XHTML code.
When writing web applications in Java, programmers can use JSP as a robust alternative to Common Gateway Interface (CGI). But developers can use JSP tags to accomplish common web development tasks using JSP tags. They can also use JSPs as dynamic elements in HTML to create dynamic web pages and collect user input via web forms. JSP further enables developers to take advantage of a wide range of enterprise Java APIs by leveraging the Java Servlet API.
Comparing JavaServer Faces, Java ServerPages and Java Servlets
JSF, JSP, and Servlet enable developers to rapidly and efficiently write a variety of web applications in Java. But they can use JSF as a web framework to simplify the development of large and complex web application development by implementing the Model-View-Controller (MVC) programming paradigm. On the other hand, JSP can be used as a server-side technology to accomplish common web development tasks through tags and to accelerate template development with client-side technologies.
At the same time, Java Servlets can be used as pre-compiled Java programs to simplify the development of web applications with dynamic content. Java programmers have the option of using JSP and Servlet interchangeably while developing web applications based on the MVC pattern. Servlet is much faster than JSP. But JSP, Servlet, allows Java developers to accomplish common web development tasks without writing additional code. Furthermore, JSP acts as a view in MVC, while Servlet acts as a controller in MVC. When web applications need to process or manipulate large amounts of data, it is advisable to use servlets instead of JSPs.
Overall, developers can leverage the features of JSP, JSF and Servlet to rapidly build custom web applications based on various business needs. They must understand that Java based technologies differ from each other in terms of design, functionality and usage. Therefore, they should take into account the types and requirements of different web applications when comparing JSF, JSP and Servlet.
