1.7. Summary
You should now have a good idea of what EJB 3 is, what it brings to the table, and why
you should consider using it to build server-side applications. We gave you an overview of
the new features in EJB 3, including these important points:
• EJB 3 components are POJOs that are configurable through simplified metadata
annotations.
• Accessing EJB from client applications and unit tests has become very simple us-
ing dependency injection.
• EJB provides a powerful, scalable, complete set of Enterprise services out-of-the-
box.
We also provided a taste of code to show how EJB 3 addresses development pain points.
Armed with this essential background, you're probably eager to look at more code. We aim
to satisfy this desire, at least in part, in the next chapter. Get ready for a whirlwind tour of
the EJB 3 API that shows just how easy the code really is.
