EJB Development using Eclipse and JBoss Training

This course is an advanced introduction to the Enterprise Java Beans (EJB) technology. It starts by introducing the concepts and ideal for someone who has never programmed using EJB. The course rapidly picks up and ends with advanced concepts that students can use in real life to complete large scale EJB based projects. The labs are done using Eclipse 3.0 and JBoss IDE 1.3.30. JBoss 3.2.3 application server is used as the server runtime.
  • Introduction to J2EE and JBoss AS
  • Overview
  • Session Beans
  • Entity Beans
  • Exceptions
  • Transactions
  • Security
  • Message-Driven Beans
  • J2EE Best Practices
  • J2EE Design Patterns
  • Business Integration and Tier Patterns
Practical Work
  Students develop session beans, including accessing a database from session bean and EJB Java Client. Next, they develop CMP Entity Beans, including EJB/RDB mapping, finder methods. Next, they develop a message-driven bean and use the Java Message Service (JMS).
What you will learn
  After completing this course, the student should be able to:
  • Understand the need for EJB
  • Understand the EJB 2.0 specification at an expert level
  • Understand how to develop, test, and deploy EJBs
  • Gain knowledge of J2EE Design Patterns and Best Practices
  • Learn the industry secrets in EJB scalability
  • Learn how to develop all types of EJB beans using Eclipse and JBoss IDE.
  This course is intended for intermediate to advanced Java programmers. System architects will find the advanced concepts especially beneficial in designing a framework.
  The student is expected to understand the core Java libraries; be familiar with web application programming, including servlets and JSPs.
  Five days.
