# The Java EE 7 Tutorial

# 33 Getting Started with Enterprise Beans

This chapter shows how to develop, deploy, and run a simple Java EE application named `converter` that uses an EJB for its business logic. The purpose of `converter` is to calculate currency conversions among Japanese yen, euros, and US dollars. The `converter` application consists of an enterprise bean, which performs the calculations, and a web client.

Here's an overview of the steps you'll follow in this chapter.

1. Create the enterprise bean: `ConverterBean`.

2. Create the web client.

3. Deploy `converter` onto the server.

4. Using a browser, run the web client.

Before proceeding, make sure that you've done the following:

- Read Chapter 1, "Overview"

- Become familiar with enterprise beans (see Chapter 32, "Enterprise Beans")

- Started the server (see Starting and Stopping GlassFish Server)

The following topics are addressed here:

- Creating the Enterprise Bean

- Modifying the Java EE Application
