What are the Java Technologies used for Web Applications?

What are the Java Technologies used for Web Applications: Java was first introduced on January 23, 1996, and will be celebrating its 24th anniversary in 2020. According to the TIOBE index, it has consistently rated top. Java has proven itself to be the best general-purpose programming language for custom software creation during the last 24 years, with 1,34,861 websites using Java as their primary language, including ESPN, SnapDeal, Alibaba, and others.

If you want to build your next online application in Java, you’ll need to make the right decision when it comes to Java web frameworks. Are you unsure how to choose an appropriate Java framework for your project? We’ll dispel your fears by providing a list of the top 5 Java online applications.


The Spring Framework is a powerful, lightweight web application development framework that is ranked first due to its exceptional ability to construct sophisticated, high-performance online applications. The Spring Framework’s fundamental features make it simple for Java developers to create enterprise-level applications.

Spring has a number of enterprise-oriented modules, such as Spring MVC, Spring Core, Spring Security, Spring Transaction, Spring Boost, and Spring ORM. Let’s have a look at some of the places where the Spring framework is employed.

  • It creates a lightweight container that can be launched without the need for a web server or application server.
  • Spring has JDBC support, which boosts productivity and decreases errors.
  • Both XML and annotation-based configuration are supported by Spring.
  • It ensures that the code is backward compatible and testable.


Oracle created JavaServer Faces (JSF) for developing enterprise applications, native applications, and online apps from Java Technologies used for Web Applications. It is to make Java-based applications’ user interfaces.

It’s a component-based MVC framework that’s been around for a while. It has an architecture that separates between application logic and representation in a clear and plain way.

JSF makes it easy for developers to construct user interfaces by allowing them to drag and drop UI components. It simplifies the development of an application’s display layer without requiring an advanced understanding of client-side technologies such as HTML, CSS, or JavaScript.

  • JSF is an essential component of Java EE.
  • It has good tools and a large library.
  • It enables current backend Java code to be extended with a web interface without requiring the main program to be changed or a new framework to be introduced.


Vaadin is one of the Java Technologies for Web Applications that allows for faster development. Developers can use it to create custom web development services.

The smooth communication between client and server is a significant benefit of this technology. From the Java Virtual Machine, Vaadin provides direct access to the DOM. Vaadin Flow is a lightweight framework that manages server-client communication routing. Vaadin enables you to integrate Vaadin components into any IDE. Because Vaadin is a cross-platform framework, there’s no need to migrate the code to another platform.

A developer does not need much HTML, CSS, or JavaScript skills to work with Vaadin. Vaadin immediately converts Java into markup.

  • Support for drag-and-drop, as well as other standout features, make creating single-page UIs for Java apps a breeze.
  • WebSocket capability allows for automatic server-client communication.
  • MVC or MVP can be used to bind data.
  • The router that supports nested routes and parameters.
  • JVM languages such as Kotlin and Scala.
  • Spring support is built-in.


Hibernate is a Java ORM (Object-Relational Mapping) database that allows you to build a robust framework. Object-relational mapping is a technique for connecting data from two disparate systems. Hibernate allows relational database management systems (RDBMS) and Java applications to communicate more effectively. It’s helpful if you’re operating in a large ecosystem and need to keep data flowing smoothly.

When working with an object-oriented language like Java, an issue known as Object-Relational Impedance Mismatch, or Paradigm Mismatch, arises. Hibernate is a framework that aids developers in overcoming these problems.

Hibernate’s queries are HQL and are similar to SQL (Hibernate Query Language). Hibernate is a Java framework that maps Java classes to database tables and vice versa.

The main file in Hibernate contains information on mapping Java classes to database configuration (the hibernate.cfg.xml file).

Cross-database solution with a lot of power.
Converting data is simple.

Google Web Toolkit (GWT)

The Google Web Toolkit (GWT) is a free, open-source web framework that aids in the development and debugging of Ajax applications in Java.

You can develop powerful, browser-based applications using GWT without having prior experience with frontend technologies such as JavaScript.

One of the most appealing aspects of GWT is that it offers cross-browser portability, history and management, internationalisation, and bookmarking, among other things.

  • It’s fully free and open-source.
  • Developer-friendly.
  • It encourages the reuse of typical web development tasks.
  • GWT apps can make advantage of Google APIs.
  • Internationalization, cross-browser portability, UI abstraction, bookmarking, and history management are some of the features available.
