How to build good web application using Java?

Java, a platform-independent, object-oriented language is used by developers and programmers for developing web applications. Programs build in Java work on different operating systems and screens.

Due to the neat and modern structure of object-oriented programming languages, developers use them for solving complex problems. The ability to write reusable code enhances the app development process.

Most of the applications that we use in our daily lives are developed using Java. Examples include Google Docs, Google Drive, and other Google products.

If you are looking to explore Java programming language in-depth and learn how to make a web application in java, the article is for you.

What is a Java Web Application?

Java web application, in general, is a collection of static resources such as HTML pages and images along with dynamic resources including Servlets, Java classes, Java Server Pages, and jars. You can deploy Java applications as Web Archive (WAR) files.

WAR file, similar to a ZIP file, contains a comprehensive collection of corresponding web applications. Want to learn more about how to make an app with java? Keep reading!

Why Java is Good for Web Development?

Java is one of the best programming languages available so far. Developers find it easy to use Java for building small to big web apps due to the following reasons.

Platform Independent

Being platform-independent means, you can view the application built in Java on any operating system and device. Developers can write code once and can reuse it anywhere.

Flexible & Scalable

Java is an object-oriented programming language and this makes it modular, scalable, and highly flexible. Not only that, it is easier to code and manage on various platforms.

Rich Set of APIs

The availability of numerous APIs for I/O, networking, database connection, XML parsing, and almost all other tasks makes it one of the most preferred options for web developers.

Highly Secure

The in-built security features such as cryptography, access control, advanced authentication, etc. make Java one of the most secure programming languages for web app development.

Responsive IDEs & Tools

To ensure high productivity, Java offers developers access to excellent tools and IDEs such as Eclipse and NetBeans. Most of the IDEs and developer tools are available for free.

Multi-Thread Support

Due to its multithreading capabilities, the language can manage multiple threads or users simultaneously. Developers don’t have to execute the same code repeatedly.

Wide Community Support

A large community base makes Java popular among developers as they get the flexibility to interact via multiple forums, seminars, and groups. This allows for extensive support.

Java vs Javascript in Web Development

The main difference between Java and JavaScript is that Java is an object-oriented programming language whereas JavaScript is an object-oriented programming script. Developers need to compile Java while JavaScript is written in text.

If you wonder is java used for web development, the straight answer is – yes. Java is primarily used to develop applications supported over browsers and devices. On the other hand, JavaScript helps create applications for browsers and HTML documents. Both Java and JavaScript use different plugins.

Web Development Java vs .NET

Java is comparatively older than .NET and focuses on all aspects of performance and productivity. Java is the key component for the popular mobile operating system Android and major other web applications.

If you think what can you build with java, there’s a never-ending list. You can build almost all types of web-applications including SaaS applications, enterprise applications, GUI applications, embedded system application, and more.

.NET, on the other hand, is a combination of two different programming languages that include C# and VB NET. The main aim of introducing .NET is to bring a language that can compete against Java. Want to learn how to create a java application, jump to next section.

Both Java and .NET languages can develop applications that can function powerfully on a wide range of platforms. The difference is that Java focuses more on Linux operating systems while .NET targets the Windows environment.

How to Build Web Application Using Java?

Let’s take a quick Look on how to build web application using java for better understanding. Java applications are compiled or executed into bytecode; they function flawlessly on any Java Virtual Machines (JVM). Not only it makes Java more portable but compatible to run over any operating system and hardware architecture.

Similar to other programming languages, Java also has a framework. The java web application framework is named Hibernate and Spring. The language is developed to have minimal dependencies. This helps simplify the web app development process. That’s certainly some of the few reasons why Java is loved by developers.

Java Technologies Involved in Web Application Development

Among many technologies that are used for java web application development, some of the widely used technologies are named below.

Java IDE

An IDE is an integrated development environment that provides an interpreter, code editor, debugger, and compiler that developers access through a graphical user interface.

Java Servlet API

Java Servlets are programs that run on Java-enabled application servers and web servers. They work on the server side and are capable to handle complex requests from web servers.

JavaServer Pages (JSP)

Java Server Pages or JSP is a server-side technology that developers use to create web applications. JSP tags enable JAVA code insertion into HTML pages.

JSP Standard Tag Library

JSTL comprises all common functions of JSP-based applications. It allows you to use standard tags instead of combining tags from multiple vendors.

JavaServer Faces

Also known as Jakarta Server Faces technology, it consists of a set of APIs that represents and manages the user interface.


This web application technology gives an object or relational mapping services. It defines the OOP mapping and set standards for mapping objects with the help of XML.

Java Persistence API

This web application technology gives an object or relational mapping services. It defines the OOP mapping and set standards for mapping objects with the help of XML.


JDBC stands for Java Database Connectivity, and API that provides universal access to data. Java manipulates and fetches data from two packages including java.sql and javax.sql.

Examples of Java Web Applications

Do you want to take a look at java web application example to know what kind of apps you can build using the OOP language? The list of web applications developed using Java is mentioned below:

· Twitter (social media app)

· Spotify (music streaming app)

· Nasa Worldwide (a virtual globe)

· Nimbuzz Messenger (an instant messaging app)

· Opera Mini (a lite web browser)

· ThinkFree Office (a desktop app)

· CashApp (mobile payment service)

· Murex (online trading system)

· Signal (encrypted messaging service)

Development Cost of Java Web Applications

The cost of developing Java web applications is based on various factors such as the app’s type and the level of complexity. If you are looking to build a web application using java such as a SaaS application, ERP application, or a Marketplace app, contact reliable Java web application developers to discuss your requirements and development cost.
