Stateful Session Bean - Complete Project (Continue ...)

Introduction

Stateful session beans are appropriate if any of the following conditions are true:

The bean’s state represents the interaction between the bean and a specific client.
The bean needs to hold information about the client across method invocations.
The bean mediates between the client and the other components of the application, presenting a simplified view to the client.
Behind the scenes, the bean manages the work flow of several enterprise beans.

Types of Enterprise Beans are

Session Beans
Stateless Session Beans
Stateful Session Beans

Entity Beans
Bean Managed Persistent (BMP) Entity Beans
Container Managed Persistent (CMP) Entity Beans

Message-Driven Bean

Write a java file and name it as CourseHome.java
Write a java file and name it as Course.java
Write a java file and name it as CourseBean.java
Write a jsp file and name it as Index.jsp
Write a jsp file and name it as CourseCart.jsp
Set the path in the command prompt

(OR)
Set the path in the system itself. CLICK HERE for details
Now compile the CourseHome.java, Course.java, CourseBean.java. CLICK HERE to see how to compile
Note: It is important that this CourseHome.class, Course.class, CourseBean.class files must be placed inside a folder University
After the java programs are compiled successfully, you can close the command prompt.
Now goto Start -> Programs -> Sun Microsystems ->Application Server PE -> Start Default Server (wait till it start and then press any key). CLICK HERE to see how to Start the Server
