Description: Java EE (Java Platform, Enterprise Edition) is a set of specifications that extends Java SE (Standard Edition) to include enterprise features such as distributed computing, web services, and transaction management. This framework provides a robust and scalable environment for developing complex enterprise applications, facilitating the creation of applications that can run on application servers. Java EE includes a series of APIs and tools that allow developers to build applications that are secure, transactional, and capable of handling multiple users simultaneously. Among its most notable components are Servlets, JavaServer Pages (JSP), Enterprise JavaBeans (EJB), and Java Persistence API (JPA), which enable the creation of dynamic web applications and efficient data management. The architecture of Java EE is designed to be modular, allowing developers to use only the components they need, thus facilitating integration with other technologies and cloud services. In the context of hybrid cloud, Java EE becomes an attractive option as it allows companies to deploy applications in both on-premises and cloud environments, optimizing resources and costs. Its ability to support microservices architectures also makes it relevant in modern software development, where agility and scalability are essential.
History: Java EE was introduced by Sun Microsystems in 1999 as Java 2 Platform, Enterprise Edition (J2EE). Since its launch, it has evolved significantly, going through several versions and name changes, eventually becoming Java EE 8 in 2017. In 2019, the platform was transferred to the Eclipse Foundation and renamed Jakarta EE, marking a new chapter in its development and governance.
Uses: Java EE is primarily used to develop enterprise applications that require high availability, scalability, and security. It is commonly employed in the creation of web applications, enterprise resource planning systems, web services, and e-commerce applications. Its architecture allows for integration with databases and other systems, facilitating the creation of comprehensive solutions.
Examples: An example of Java EE usage is an e-commerce platform of a large company that uses Servlets and JSP to manage user interactions, while EJB is used to handle business logic and data persistence through JPA. Another example is a human resources management system that implements web services for communication between different modules of the application.
