Description

This course teaches about the design and development of Enterprise Java Beans. It differentiates between the two different kinds of beans, session and entity beans, and explains their purpose. It also explains how to create the different kinds of session beans, how to use session beans appropriately, and how to work with the EJB Security Model.

Audience

The targeted audiences for this course are System Administrators, Application Developers, System Analysts, Software Engineers, and Programmer/Analysts. Learners should be experienced with object-oriented design and the Java programming language. It would be helpful for learners to be familiar with distributed programming (multi-tier architecture), relational or object database programming, transactions, and component technology.

Prerequisites

Objective

• Identify situations in which EJBs can be used.
• Identify the types of EJBs.
• Match the EJB components with their uses.
• Create an Enterprise bean class and the interfaces.
• Select the situation that causes an EJB to transit from one state to another.
• Identify the differences between stateful and stateless session beans.
• Develop and deploy session beans.
• Implement and propagate declarative and programmatic security.

Topics Include
