Description

This final course in the series covers the function and purpose of entity beans, container-managed and bean-managed persistence, EJB transactions, and deployment issues, including packaging and assembling EJBs.

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

(Currently no course prerequisite information)

Objective

• Identify the concept and components of an entity bean.
• Understand the implementation of BeanManaged Persistence (BMP) beans and ContainerManaged Persistence (CMP) beans.
• Identify transactions, transactional attributes, and isolation levels.
• Understand the implementation and deployment of beanmanaged and containermanaged transactions. Exceptions in the context of transactions will also be covered.

Topics Include

Unit 1: Entity Beans

• Identify the type of bean and the reason why it should be used to create a specified component in a scenario.
• Complete the diagram that represents the operational process of an entity bean.
• Complete the code for creating the remote interface of an entity bean.
• Identify the error in the code that creates the home interface of an entity bean.
• Identify the code that is used to create the primary key class of an entity bean.
• Complete the code for creating the bean class of a BMP bean.
• Identify the piece of code that is used to describe the various attributes of a BMP bean in the deployment descriptor of the bean.
• Complete the command used to package a BMP bean into a jar file.
• Deploy a BMP bean by using WebSphere.
• Complete the code for a client that invokes a BMP bean.
• Identify the code used to create the bean class of a CMP bean.
• Identify the piece of code that is used to describe the various aspects of a CMP bean in the deployment descriptor of the bean.
• Complete the code for a servlet that invokes a CMP bean.

Unit 2: Transactions

• Match the activities involved in a transaction with the transaction properties that they ensure.
• Identify the transactional attribute that should be used in a specified situation.
• Match transactions with the isolation levels that should be associated with them.
• Identify the code used to manage transactions programmatically by using the UserTransaction interface.
• Match SessionSynchronization method declarations with their definitions.
• Identify the piece of code to be included in the deployment descriptor of a bean to make it run in a specified transactional context.
• Identify the code used to propagate exceptions to the container in a container-managed transaction.
