Java Enterprise Edition (Java EE), now known as Jakarta EE, is a collection of specifications and technologies that extend the Java Platform, Standard Edition (Java SE) to provide a robust and scalable platform for developing enterprise-level applications. Jakarta EE is designed for building large-scale, distributed, and mission-critical applications that can run in enterprise environments. Here are some key aspects and components of Jakarta EE:

1. Component-Based Architecture: Jakarta EE applications are typically built using components, which are modular units of functionality. The most common components in Jakarta EE are Enterprise JavaBeans (EJBs), servlets, JavaServer Pages (JSP), and Java Persistence API (JPA) entities.

2. Distributed Computing: Jakarta EE supports distributed computing by providing mechanisms for remote method invocation and messaging. This allows applications to be distributed across multiple servers and nodes in a network.

3. Web Services: Jakarta EE includes support for building and consuming web services. This enables applications to communicate with each other using standards like SOAP (Simple Object Access Protocol) and REST (Representational State Transfer).

4. Security: Jakarta EE provides a comprehensive security framework with features such as authentication, authorization, and encryption to ensure the confidentiality and integrity of data in enterprise applications.

5. Transaction Management: Jakarta EE supports distributed transactions, allowing multiple database operations to be treated as a single atomic transaction. This ensures data consistency in enterprise applications.

6. Persistence: Jakarta EE includes the Java Persistence API (JPA) for object-relational mapping (ORM), making it easier to work with databases in a standardized way.

7. Messaging: Jakarta EE provides support for messaging through technologies like Java Messaging Service (JMS), which allows applications to exchange messages asynchronously.

8. Integration: Jakarta EE is designed to integrate with various middleware and infrastructure components commonly used in enterprise environments, such as application servers, databases, message brokers, and identity providers.

9. Scalability and Load Balancing: Jakarta EE applications can be deployed on application servers that offer load balancing and clustering capabilities, enabling them to scale horizontally to handle increased loads.

10. Portability: Jakarta EE applications are designed to be platform-independent, allowing them to run on different Jakarta EE-compliant application servers.

11. Community-Driven: Jakarta EE is developed through a community-driven process and is now governed by the Eclipse Foundation. It is open source and encourages contributions from developers and organizations.

12. Java EE to Jakarta EE Transition: Jakarta EE is a continuation of Java EE but with a different governance model. Many of the specifications and APIs in Jakarta EE are similar to their Java EE counterparts, making it easier for organizations to transition from Java EE to Jakarta EE.

Jakarta EE is a powerful platform for building enterprise-level applications, and it continues to evolve to meet the changing needs of modern enterprise development. Developers working on large-scale and mission-critical applications often choose Jakarta EE for its extensive set of features and standardization.
