Jakarta EE Overview

This is the repository for the LinkedIn Learning course Jakarta EE Overview. The full course is available from LinkedIn Learning.

Do you need an overview of Jakarta EE as a whole? In this course, Java Champion and Jakarta EE Developer Advocate Ivar Grimstad guides you through the purpose of Jakarta EE and the specifications that you will need to understand. Ivar presents a quick overview of Jakarta EE, its specifications and implementations, the containers you will use for different component types, and the standard units for deployments. He goes into more depth on the Jakarta EE Platform, then dives into Web Profiles and Core Profiles. Packed with useful tips and practical challenges, this course can help you to decide the next steps in your Jakarta EE journey.

See the readme file in the main branch for updated instructions and information.

Instructions

The starting point for the challenges are in the main branch of this repository. The solutions are in separate branches. You can use the branch pop up menu in github to switch to a specific branch and take a look at the course at that stage, or you can add /tree/BRANCH_NAME to the URL to go to the branch you want to access.

Branches

The branches are structured to correspond to the solution videos in the course. The naming convention is CHAPTER#_MOVIE#. As an example, the branch named 02_03 corresponds to the second chapter and the third video in that chapter. The main branch holds the starting point for all the challenges.

When switching from one branch to the next after making changes to the files, you may get a message like this:
