CREATING WEB APPLICATIONS ON JAVA

The requirements for the functionality of web projects and websites of commercial companies are already so wide that simple Internet business cards and landing pages with a set of static information do not satisfy modern requirements. Sites of successful companies today are not a set of HTML documents with a list of services and contact information, but executable web programs that provide a client with a variety of web services.

Developing Java web applications will allow you to safely integrate any digital solutions into your company’s website – from e-commerce and online sales tools to authorization and booking services. At the same time, the use of universal Spring-type frameworks for the Java platform simplifies the development of highly loaded, scalable and reliable enterprise-level web applications (Enterprise solutions). The approach to developing enterprise-type web applications using frameworks makes it possible to create lightweight and fast systems from a variety of related web services and web services.

The vast majority of the sites that we visit every day are actually web applications. These programs are stored in the form of program code on the server and come into effect when prompted by a browser on a user’s computer or smartphone. Due to the fact that the web application is executed both on the server and on the end device, most of them are universal tools. Unlike regular executable programs, web applications do not need to install or update, and they are not tied to the same operating system. Investing in the development of a cross-platform web program is more profitable than investing in the creation of several executable applications for Windows, MacOS, Android or iOS.

No less important is the fact that web applications can be presented not as a single software solution, but be a collection of several web services at once, each of which is launched in a browser with a certain sequence of user actions. This is important because the capabilities of the server on which web applications are stored and executed exceed the potential of desktop computers, tablets and smartphones.

In addition, web applications are scalable and run immediately for many connected clients. To improve the quality and fault tolerance of a web program, it is enough to improve the hardware of the server or to improve the program code that is stored on the web app server.

That is why Java web application development is a good option for writing service-oriented solutions at the level of large companies and enterprises. So, in the form of such web applications, and not in the form of end programs, the majority of online stores and payment systems of the “client-bank” type, cashback services and web-based financial transfer systems, electronic marketing and online advertising solutions have been made. And, of course, web applications include social media pages, search engines, online email clients, text and graphic Internet editors, browser games, and much more.

The main advantages of web applications written in Java are due to the advantages of this programming language:

• cross-platform: Java web applications can run on any devices that can be connected to a web server using the Internet protocol of the browser;
• reliability: Java is one of the most popular programming languages ​​with a large number of ready-made tools, debugged solutions, libraries and frameworks;
• security: Java technology allows you to regulate the security policy of web applications and to differentiate access rules;

• performance: due to the so-called multithreading, Java uses the hardware capabilities very effectively, which is important for programs with animation and for processing large amounts of data.

As a result, the creation of Java web applications has become the quality standard for large projects with high demands on productivity, resiliency and security, such as financial, banking and electronic trading systems.

The principle of operation of any web application involves the use of the main (back-end) part of the web program that runs on the server, and the client (front-end) part of the web application that runs on the user’s device.

The main calculations in any case occur on the server. After a request is received from the browser of the client device, the server part of the web application, using information from the database, generates the result of the calculations. This result is transmitted to the end device, processed by the client part of the web application, and executed in the web browser as a user interface.

The creation of Java web applications is essentially the creation of server programs, the so-called servlets. These Java applications expand the capabilities of the server and allow performing a variety of functions:

• after a user request, the so-called virtual Java machine starts on the server;
• it executes one or another servlet, that is, it powers a specific web application written in Java;

when the servlet is finished, the web server will send the result of the calculation to the target device in the form of a dynamic web page.

Due to the fact that Java programs run in a virtual Java machine environment that can be deployed on any computer architecture, this technology is not tied to any one platform. Web applications written in Java can run on any device and server, regardless of the operating system or hardware type.

At the same time, using frameworks of the Spring type simplifies and automates the configuration of servlets using a wireframe model. Automation and acceleration of large web applications is due to the fact that the Spring framework involves the use of the so-called central servlet, which redirects user calls to it or other web services, web services and web components. It is the support of infrastructure at the application level that facilitates the rapid construction and easy execution of the corporate business logic of the program without changing configurations and additional settings.

The company Avada Media is engaged in the development of any web solutions where the use of Java technology is optimal. First of all, we can talk about such projects as:

• e-commerce systems, online stores and online sales systems;
• web sites for registration and booking services;
• online resources for education, multimedia entertainment projects, games;
• web apps for accounting and logistics, CRM and ERP systems;
• FinTech projects, cashback, payment and transfer systems;

• MarTech and AdTech projects, online marketing and advertising systems etc.

For the development of web applications in Java, we attract highly qualified programmers (developers), testers (QA) and system engineers (DevOps). All our web programs written in Java undergo mandatory configuration testing to verify their functionality on different devices, as well as load testing and security testing to verify the fault tolerance, reliability and security of web applications.
