What is Java EE and what does it stand for?
Java EE, also known as Java Platform, Enterprise Edition, is a set of specifications for developing and deploying large-scale, distributed, and multi-tiered enterprise applications. It provides a robust and scalable platform for building complex systems, including web services, databases, and messaging systems. Java EE is designed to simplify the development process by providing a set of APIs, tools, and protocols that enable developers to create reusable and maintainable code.
Java EE was first introduced in 1998 and has since become a widely adopted standard for enterprise software development. It is used by many organizations around the world to build complex systems, including banking, finance, healthcare, and e-commerce applications. Java EE is maintained by Oracle Corporation, which provides the reference implementation for the platform.
What is Jakarta EE and how does it relate to Java EE?
Jakarta EE is the new name for the Java EE platform, which was rebranded in 2018. The rebranding was done to reflect the changing landscape of the Java ecosystem and to provide a clearer distinction between the Java SE (Standard Edition) and Java EE platforms. Jakarta EE is built on top of the Java EE specifications and provides the same set of APIs, tools, and protocols for developing and deploying enterprise applications.
The main difference between Java EE and Jakarta EE is the governance model and the licensing terms. Jakarta EE is now managed by the Eclipse Foundation, a non-profit organization that provides a vendor-neutral platform for developing and maintaining open-source software. This change has enabled the Jakarta EE community to take a more active role in shaping the future of the platform and to provide a more open and inclusive development process.
What are the key differences between Java EE and Jakarta EE?
One of the key differences between Java EE and Jakarta EE is the licensing terms. Java EE was licensed under the CDDL (Common Development and Distribution License), which was owned by Oracle Corporation. Jakarta EE, on the other hand, is licensed under the Eclipse Public License (EPL), which is a more permissive license that allows for greater flexibility and freedom.
Another key difference is the governance model. Java EE was managed by Oracle Corporation, which had a significant influence over the direction and development of the platform. Jakarta EE, on the other hand, is managed by the Eclipse Foundation, which provides a more open and inclusive governance model that allows for greater community participation and input.
