Java needs no introduction. Almost every person worldwide acknowledges Java’s potential in web application development. With Java, one can easily create highly secured and dynamic applications. Whether you wanna be a developer yourself or need a web app developed by an experienced Java developer, there are several technologies involved that you should know about.

But, what is a web application? Let’s check it out!

Web Application in Java

A web application is a client and server-side software application that is distributed on more than one remote web server instead of running on the operating system like other native apps. A user can access web applications through web browsers with an active internet connection.

For developing a web application in Java, it’s important to choose technologies that work on servers and will make the process easier. So what are these technologies we are referring to? Does learning each of them is essential? How do they help in Java web application development?

You might have a few more questions about it, so let’s answer them all under the next section.

Java Web App Technologies to Know About

Undoubtedly there are numerous technologies in Java that are used for web application development. But, in this article, we will only focus on the ones that are used the most.

Netbeans is an open-source, free integrated development environment for the development of web, mobile or desktop applications using Java. It provides complete integrated support for the development cycle i.e. from creation to profiling, debugging and deployment.

JavaServer Pages or JSP is a collection of technologies that help the creation of platform-independent and dynamic web applications. JSP allow you to add servlet code snippets into a text-based document. JSP document only includes two types of text, i.e., static data (expressed in HTML, XML or WML) & JSP technology elements (determining the way to construct dynamic content page).

Java Servlet is cannot be defined as one technology because it’s used for various purposes. It is a technology used to create web apps, an API to provide classes and interfaces, a class that enhance the server capabilities and responds to every incoming request, and an interface implemented for creating any Servlet.

JavaServer Faces or JSF is a set of APIs that represents components of UI and handles their states, manages event & input validation, supports internationalization and accessibility, and defines the navigation of a page. JSF is designed to offer flexibility and establishing standards for developing server-side interfaces. JavaServer Faces leverages standard UI and web-tier concepts and does not limit developers to a particular device, protocol or language. JSF also gives a custom JSP tag library and custom renderer for rendering to a client.

  • Java Persistence API (JPA)

Java persistence API offers a mechanism for Java developers an object-relational mapping facility that helps in managing relational data in Java applications. It gives a platform to work with objects rather than using SQL.

Java Database Connectivity is an API of Java to connect and execute database queries. JDBC includes a set of interfaces and classes written in Java language. Using the standard classes and interfaces, developers can design apps that connect with SQL databases.

The Java Message Service is a messaging standard that enables Java Platform Enterprise Edition (Java EE) components of the application to create, send, receive and read messages. Apart from that, JMS also allows loosely coupled, asynchronous and reliable communication.

The JavaMail API offers a protocol-independent and platform-independent framework to design messaging and mail applications. It is available as an optional package to be used as the Java SE platform and Java EE platform.

JavaBeans are classes that encapsulate several objects into one object known as a bean. A JavaBean is a class that must be serializable, have a no-argument constructor, and should also provide methods to set or get values of properties.

  • Java Naming and Directory Interface (JNDI)

The Java Naming and Directory Interface (JNDI) is an API that renders naming and directory functionality to applications. It allows Java web app users to discover and search resources and data through names.
