The term "Java and JavaEE" refers to a collection of technologies and platforms used to develop scalable, secure, and platform-independent enterprise applications. Java serves as the core object-oriented programming language, while JavaEE (Java Platform, Enterprise Edition – now known as Jakarta EE) extends it with enterprise-specific features such as transaction processing, security, web services, and persistence. JavaEE is particularly suited for multi-tier applications that demand high levels of reliability, scalability, and integration.
Servlet Management: Handling HTTP requests in web applications via server-side Java components.
Enterprise JavaBeans (EJB): Providing reusable business components for transactions, security, and persistence.
JPA (Java Persistence API): Object-relational mapping for storing and managing data in databases.
Web Services (REST/SOAP): Developing and delivering APIs for integration with other systems and applications.
JMS (Java Message Service): Supporting asynchronous communication through messaging systems to decouple services.
Security Management: Authentication and authorization through role-based access control.
JSF (JavaServer Faces): Framework for developing user interfaces for web applications.
Transaction Management: Managing distributed transactions across multiple resources.
Deployment in Application Servers: Support for server-side deployment in environments such as WildFly, GlassFish, or Payara.
An insurance company develops a modular web application for contract management and claims processing using JavaEE.
