INTRO-JAVA-J2EE: Introduction To Java And J2EE

This content is for induction type training content for developers starting with Java. Upon completion they can be entitled as Web application development using J2EE.

Java Enterprise Edition (J2EE is a Java standard for running client-server Java applications on a "Java Application Server." Despite the fact that there are numerous commercial and open source application servers on the market, this specification ensures that the programming paradigm is consistent and that a Java EE application's mobility and rich capabilities are enhanced.

J2EE was the moniker given to earlier versions of the Java EE specification, and it is still used by many individuals.
