Enterprise JavaBeans technology is the server-side component architecture for developing and deploying business applications in Java EE. The latest release of the technology, JSR 318: Enterprise JavaBeans 3.1, which is available in the Java EE 6 platform, further simplifies the technology and makes many improvements. There are two types of EJB components: Session beans and  Message-driven beans. 

In this tutorial, you will create a JEE 6 Web Application and add the following components to it - Stateless Session Bean, a Servlet, and a JSP. The  JSP will contain a form allowing you to specify a name. The form will submit to a Servlet which will read the name entered as the form parameter. The Servlet will pass the name to a sayHello method that is in the Session bean that you will create.
