Learning Java EE 8 [Video]

Overview of this book

Java EE provides a standard set of specifications that can be used to develop standardized applications, independent of the vendor. Enterprise applications do not change that often, and hence we need a robust platform such as Java EE to ensure sustainability. Thus, this comprehensive course—covering all the features and APIs in Java EE—will be helpful for developers. It also answers questions related to how Java EE compares to the Java language, should developers transition to it, and what types of application would benefit from it. Both small businesses and large enterprises have benefitted from the various APIs provided by the Java EE platform to build dynamic web apps. This therefore remains one of the key skills sought by hiring companies. This course starts by exploring the core JAVA EE components. Moving further you will learn all about HTTP endpoints. You will learn how to map domain entities with JPA. Cross-cutting concerns will be covered exhaustively. This course teaches you how to deal with Asynchronous behavior. You will learn to access external systems. You will also learn about the asynchronous communication protocol. By the end of the course, you will be able to develop a car management enterprise application.

synchronous EJBs
This video shows how to define asynchronous EJB methods. It covers the possibilities and implications of asynchronous execution within EJBs. - Annotate EJB business methods with @Asynchronous to invoke them asynchronously - Define Future return types if a direct result is required - Beware of scopes of managed beans in asynchronous methods
