Java web applications are witnessing steady growth in their adoption across various applications and industry sectors. Organizations are adopting Java-based web applications for building cross-platform, secure, and scalable enterprise solutions.
The steady evolution of web frameworks, such as Jakarta EE and Spring Boot, offering several options, is driving growth, particularly in developing cloud-native and microservices applications. Cloud-native involves designing and running applications that take full advantage of cloud computing models, such as distributed infrastructure, scalability, and elasticity. Microservices refers to an architectural style that enables an application to segregate into independent and small services, making each unit responsible for performing a single functionality.
Furthermore, there is increasing demand for maintainable and robust backend systems from across several industrial sectors. With Java capabilities extending to the organizational requirements, several businesses operating across diverse sectors, including government, education, healthcare, and finance, prefer high-performance and reliable solutions.
Features of Java Web Applications:
Enterprise-Level proficiencies:
Several large-scale enterprise systems, including those in healthcare, e-commerce, and banking, utilize Java as their underlying framework. With Java incorporating advanced technologies such as Hibernate, Jakarta EE, and Spring, which offer a wide range of capabilities, Java web applications are well-suited to handle complex business logic efficiently, along with enterprise integrations and transaction management.
Integration-Friendly:
Java web applications enable seamless integration with web services, such as REST and SOAP, and Message brokers like RabbitMQ and Kafka. It also allows easy blending with legacy systems and Databases, including NoSQL and SQL.
Platform Independence:
Due to the inclusion of the Java Virtual Machine (JVM), Java can exhibit platform independence, enabling it to run across various cross-platform web solutions. As a result, Java web applications can run on any system but require support for the JVM.
Scalability:
Java enables integrations of specific important features such as load balancing support, garbage collection, and multithreading, making it an ideal platform to host web applications, especially those that are generating high traffic. As a result, some of the top companies, such as Netflix, LinkedIn, and Amazon, employ Java-based components across their applications.
Rich Ecosystem and Tools:
Java features an extensive set of ecosystems, including libraries, servers, and frameworks. While Struts, JSF, and Spring Boot constitute the frameworks, WildFly, Jetty, and Apache Tomcat include the Servers. Libraries include several aspects, from PDF generation to web sockets. With all these capabilities, Java web applications are ideal solutions for developing robust web applications.
Security:
Nowadays, there is increasing importance for technologies that promise security due to the proliferation of cyberattacks. Java, with its built-in security attributes, offers role-based access control (RBAC), authorization mechanisms, and secure authentication through Spring Security. At the same time, it safeguards the software from frequent web vulnerabilities.
Java Web Applications Support Community:
Java developer community includes developers who are running into millions worldwide. Moreover, Java, with its extensive libraries, forums, and documentation, makes it easy to access third-party tools, talent, and support.
Supports Modernistic Web Applications:
Java supports CI/CD pipelines with tools like Maven and Jenkins and cloud deployment through Google Cloud, Azure, and AWS. It also can support microservices architecture employing Spring Cloud and Spring Boot.
Some Real-World Examples of Java Web Applications:
Learning Management Systems: Java ensures in the development of web platforms for use across universities to help them manage student data, exams, and access courses. Some specialities of these platforms include grading dashboards, conducting online exams, and course enrollment. MongDB, Thymeleaf or JSF, and Spring Boot are the technologies engraded into the platform.
Telecom Billing & CRM Platforms:
Java web applications facilitate billing, plan management, and customer onboarding. The integrated technologies include Oracle DB, Kafka, Spring, and Java. The platform features telecom hardware, API-based integration with mobile apps, and multi-tenant architecture.
Enterprise Resource Planning (ERP) Systems:
Java supports the building of ERP platforms for managing finance, HR, and supply chain functions. They feature financial accounting, HR management, and Inventory tracking. Enables workflow automation, high scalability, and modular design. The tech stack for these applications includes the use of MySQL, Angular or React for front-end, and Spring Boot.
Other examples include Healthcare Information Systems, E-Governance Portals, and Banking & Financial Systems.
