In this chapter, we will go a little deeper and learn how to create, deploy, and assemble Enterprise JavaBeans, which are at the heart of most Enterprise applications. Additionally, you will learn how to use Maven, a popular build tool, which can ease the packaging process of our beans.
In more detail, here is what you will learn in this chapter:
- What changes are introduced by the new EJB 3.2 specification
- How to create a Java EE 7 Maven project
- How to develop a singleton EJB
- How to create stateless and stateful Enterprise JavaBeans
- How to add and manage schedulers and timers to your application
