Create the following directory structure under some logical parent directory, such as c:\ejb_example. This directory structure is for development purposes only; the deployment files will be zipped into a jar file in a moment and deployed to jboss.

create the bean class as src\server\com\examples\HelloBean.java. This class is a stateless session bean and contains our business logic. In this case it prints out the exciting and always useful "Hello! World".

Create the remote interface as src\shared\com\examples\Hello.java. This is the interface that remote clients talk to instead of talking directly to the bean class, HelloBean. Notice that its only method is sayHello(), which is the business method in HelloBean.

Create the home interface as src\shared\com\examples\HelloHome.java. This interface will be used to create an instance of the Hello interface when we want to execute the sayHello() business logic.

create the client as src\client\com\examples\HelloClient.java. This is the "remote" client that will use our session bean. First, it uses the InitialContext to get a handle to HelloHome. It then uses the HelloHome interface to create hello. hello is a remote interface representing our bean class. After hello is used to execute the business logic (sayHello), the bean is released via the remove method.

Create the ejb-jar.xml file in target\server\META-INF. This deployment descriptor contains information that the jboss EJB container needs in order to deploy and run our EJB.

Create the jndi.properties file in target\client. This file defines properties that are required in order to use JNDI to find EJBs on the network.
