In this tutorial we will learn how to create our first Enterprise JavaBean. We will then deploy this EJB on a production class, open source, and free EJB Server; JBoss. JBoss is a really popular EJB Container and is used by quite a lot of organizations World wide. We will thus also learn how to install and run JBoss Server. The client for our EJB will be a JSP page running in a separate Tomcat Server.
