Review of Object Oriented Concepts

• Conventional vs Object Oriented Programming
• Inheritance, Abstraction and Polymorphism

Getting Started with Java

• • operators
  • comparison and logical expressions
  • for, while and do
  • switch
• Using Strings
• Specialising in a Subclass

• • extending a class
  • overriding SuperClass methods
  • default constructor and implicit constructor chaining

Enterprise Java Overview

• Developing Java Servlets
• Introduction to Java Server Pages (JSPs)
• Java for the Enterprise

Introduction to Enterprise JavaBeans

• Benefits of using EJB technology
• Strengths and weaknesses of the EJB Specification
• Services provided by J2EE/EJB servers
• Comparison of JavaBeans and Enterprise JavaBeans

EJB Architecture

• How containers work in an EJB server
• Relationships between home, remote, EJBObject, and enterprise bean
• Transaction, security, and naming service integration
• Persistence management - containers
• Understanding and comparing session and entity beans
• The XML deployment descriptor
• EJB application packaging - the JAR file

Overview of EJB 1.1 vs EJB 2.0

• Availability of local interface access for better performance
• Additional method support in home interfaces
• Differences in entity bean implementations
• Direct data model support in entity beans
• Message driven beans
• Deciding whether to use EJB 1.1 or EJB 2.0

Writing Session Beans

• Structure of a session bean, leveraging inheritance
• SessionBean methods and initializers
• Use of UML to model bean creation
• Best practises for SessionContext and re-use
• Trade-offs between use of transient data and ejbPassivate
• Statefull and stateless session beans
• Effects of concurrency on session beans
• Access to system services: file system and networking

Writing the EJB Interfaces

• Home and remote interfaces
• Transport issues : RMI
• Exception handling
• EJBHome and EJBObject interfaces
• Handle and HomeHandle APIs
• Common traps to avoid

Exception Handling

• Distinction between business and callback methods
• Application failure notification and recovery
• System and application failures and the EJB runtime model
• Planned vs unplanned failures
• Representation of failures and exception inheritence in UML
• Handling side effects of failure
• Proper use of EJB application exceptions and EBJException
• Application and system specific exceptions

EJB 2.0 Interface Enhancements

• Interface methods
