“Jakarta” in the context of Java refers to Jakarta EE, formerly known as Java EE (Enterprise Edition). Jakarta EE is a set of specifications that extends the Java Platform, Standard Edition (Java SE) to provide a comprehensive enterprise-level platform for developing and deploying enterprise Java applications.

Here are some key points about Jakarta EE:

1. Evolution from Java EE: Jakarta EE was created as a continuation of Java EE, with the goal of moving away from Oracle’s stewardship and making it more community-driven. It maintains backward compatibility with Java EE.

2. Enterprise-Grade Java: Jakarta EE is designed for developing large-scale, mission-critical enterprise applications. It provides specifications for various services and APIs, including Servlets, Enterprise JavaBeans (EJB), JavaServer Pages (JSP), Java Persistence API (JPA), and more.

3. Component-Based Architecture: Jakarta EE promotes a component-based architecture for building enterprise applications. Developers can create reusable components like Servlets, EJBs, and CDI (Contexts and Dependency Injection) beans to build modular and maintainable applications.

4. Containers: Jakarta EE applications run within containers that provide runtime environments with services like transaction management, security, and resource pooling. Two common types of containers are web containers (for servlets and JSP) and EJB containers (for enterprise beans).

5. Enterprise Integration: Jakarta EE provides APIs and specifications for enterprise integration, including messaging via Java Messaging Service (JMS), web services using JAX-RS (Java API for RESTful Web Services) and JAX-WS (Java API for XML Web Services), and more.

6. Persistence: Jakarta EE includes the Java Persistence API (JPA) for object-relational mapping (ORM). JPA allows developers to work with databases using Java objects.

7. Security: Security is a critical aspect of Jakarta EE. It provides authentication, authorization, and encryption features to ensure that enterprise applications are secure.

8. Community-Driven: Jakarta EE is governed by the Eclipse Foundation, which oversees the development of Jakarta EE specifications in a transparent, open-source, and community-driven manner.

9. Portability: Jakarta EE applications are designed to be portable across different Jakarta EE-compatible application servers. This means that you can develop your application on one server and deploy it on another, provided both support Jakarta EE specifications.

10. Microservices: Jakarta EE can be used to build microservices, although microservices are more commonly associated with lightweight frameworks like Spring Boot and Quarkus. Jakarta EE’s modularity and component-based architecture make it suitable for microservices development in certain cases.
