Jakarta EE is a mature platform that's widely used around the world. It is also a standard that has evolved through the hard work of individuals, vendors, groups leaders, and communities. It has a whole market and ecosystem around it, with millions of users, which also means a big and active community that is always willing to help it move forward.
For those reasons, the purpose of this book is to meet the needs of those professionals who depend on Jakarta EE to deliver really awesome enterprise solutions, not only talking about real solutions to real problems but also showing how to implement those solutions in a practical way.
The book starts with a quick overview of what Jakarta EE is and the improvements in version 8. Then, it takes you on a hands-on journey through the most important APIs.
You will learn how to use Jakarta EE for server-side development, web services, and web applications. You will also take a look at how you can properly improve the security of your enterprise solutions.
No Jakarta EE application is good enough if it doesn't follow the standards, and for that, you can count on the Jakarta EE application servers. This book will teach you how to use the most important servers on the market and get the best that they have to offer for your project.
From an architectural point of view, the book will cover microservices, cloud computing, and containers. Also, it will not forget to give you all the tools you need to build a reactive Jakarta EE application using not only Jakarta EE features, but also Java core features such as lambdas and completable futures.
The whole Java world is all about the community, so we will also show you how community-driven professionals can improve the results of their projects and even go to higher levels in their careers.
