Part 1

Overview of POJOs
and lightweight frameworks

In part 1, you'll get an overview of developing with plain old Java objects ( POJO s)

and lightweight frameworks such as Spring, Hibernate, and JDO . In chapter 1,
“Developing with POJO s: faster and easier,” we'll explore the basics of POJO s and
lightweight frameworks and how they differ from Enterprise JavaBeans. As the title
implies, you'll see how POJO s and lightweight frameworks make development eas-
ier and faster. We'll look at a simple design that uses Hibernate for persistence and
the Spring framework for transaction management and application assembly.
In chapter 2, “ J2EE design decisions,” we'll look at some of the key decisions
that you must make when developing enterprise Java applications, including
when to use the POJO approach. You'll learn about the different ways you can
organize and encapsulate business logic, access databases, and handle database
concurrency. The options described in this chapter are explored in detail in the
rest of the topic. You'll see an example of how a project team might go about mak-
ing these design decisions for their application. This chapter also introduces the
example application that is used throughout the topic.
