JEE

JEE is an acronym that can refer to more than one topic. The two most common meanings are the Joint Entrance Examination in India, a national-level set of admissions tests for engineering programs, and the Java Platform, Enterprise Edition, an enterprise Java platform now branded as Jakarta EE.

In the Indian higher education context, the Joint Entrance Examination comprises JEE Main and JEE Advanced. JEE Main is a national entrance exam administered by the National Testing Agency and serves as a criterion for admission to many undergraduate engineering programs in national and state institutes, including NITs, IIITs, and other centrally funded institutions. JEE Advanced is a separate examination conducted by a consortium of IITs for admission to the Indian Institutes of Technology. JEE Main Paper 1 targets B.E./B.Tech programs and assesses Physics, Chemistry, and Mathematics, largely through computer-based questions; Paper 2 covers B.Arch and B.Planning. The exams are typically held annually in multiple sessions. Eligibility generally includes completion of secondary education with required subjects and a specified number of attempts, with JEE Advanced admissions restricted to candidates who perform well in JEE Main.

Jakarta EE, formerly Java Platform, Enterprise Edition, is a collection of specifications for building and running enterprise Java applications. It originated as Java EE and was transferred from Oracle to the Eclipse Foundation and rebranded. Jakarta EE defines APIs such as Servlet, CDI, EJB, JPA, and JAX-RS, which are implemented by application servers like GlassFish, WildFly, WebLogic, and WebSphere. The transition from the javax to the jakarta namespace began with Jakarta EE 9, with subsequent releases continuing to expand the platform and align with modern deployment models, including cloud and microservices environments.

In summary, JEE may denote either a major engineering admissions framework in India or a widely used enterprise Java platform, depending on the context.
