As we all know, Java is the foundation for virtually every type of networked application and is the global standard for developing and delivering embedded and mobile applications, games, Web-based content, and enterprise software. It’s necessary in computer technology.
What is Java?
Java is a general-purpose computer programming language which is concurrent, class-based, object-oriented, and specifically designed to have as few implementation dependencies as possible. Its purpose is to let application developers “write once, run anywhere” (WORA), meaning that code that runs on one platform does not need to be recompiled to run on another. Java applications are typically compiled to byte code that can run on any Java virtual machine (JVM) regardless of computer architecture.
Java Technologies to Use in Web Applications
There are too many Java technologies, so this article will describe only the ones most frequently used. The number of technologies listed here can be a lot. Keep in mind that you will not need to use them all. In fact, a web application often consists of nothing more than one page created with the JavaServer Pages (JSP) technology. Sometimes you will combine three or more such technologies. No matter how many you end up using, it’s good to know what is available to you and how you can use each one in a web application.
1. Java Servlet API
The Java Servlet API lets you define HTTP-specific classes. A servlet class extends the capabilities of servers that host applications that are accessed by way of a request-response programming model.
2. Java Server Pages Standard Tag Library
The Java Server Pages Standard Tag Library (JSTL) encapsulates core functionality common to many JSP technology-based applications.
3. Java Message Service API
Messaging is a method of communication between software components or applications. A messaging system is a peer-to-peer facility. Each client connects to a messaging agent that provides facilities for creating, sending, receiving, and reading messages. By combining Java technology with enterprise messaging, the Java Message Service (JMS) API provides a powerful tool for solving enterprise computing problems.
The Importance of Developing Java Web Application
Java web development applications are available including a web browser and are well-liked since it provides the simplicity of employing the browser as the user customer. Web applications are mainly programs that work on many different computer systems and interact via a network or server. Java Servlets and JavaServer Pages enable programmers to influence the potential of the Java application platform for developing object-oriented, scalable, n-tier applications. Web application developments are utilized for online retail sales, weblogs, web mail, discussion boards, and a lot more.
Several other development applications employ solely the Java programming language that is ideal owing to its flexibility. A web application development can be made as easy as a web page which displays the latest present time and venue or as critical and composite as a series of web pages where one can seek and reserved the effective and convenient flight details, car rentals, hotel room reservation according to the need. Moreover, often one can merged these advanced technologies to employ in the development of web application.
