This 4-day Enterprise JavaBeans course is an advanced introduction to the Enterprise JavaBeans (EJB) technology. It starts by introducing the concepts and is 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.

• Introduction to EJB. Explain the general principles of:
  • Application Server
  • Distributed Computing
  • Distributed Transactions
  • Distributed Security
• The Session EJB specification.
• Building Session EJB using VisualAge for Java.
• The Entity EJB specification.
• Building Entity EJB using VisualAge for Java.
• EJB Exceptions
• EJB Transaction Management
• Advance EJB concepts. WebSphere Application Server specific details.
  • Advanced CMP EJB data mapping.
  • EJB pooling mechanism.
  • Exceptions and Transaction control in WebSphere Application Server.
  • Access Beans.
  • Advanced finder logic.
  • Achieving high scalability and concurrency.

Students develop stateless and stateful session beans using VisualAge for Java. Then they develop a CMP Entity bean. The purpose is to display the use of development tools to improve EJB development productivity. Students then assemble various components developed in earlier exercises to build a complete online banking application.

After completing this course, the student should be able to:

• Understand the need for EJB.
• Understand the EJB1.1 specification at an expert level.
• Understand how to develop EJB using VisualAge for Java.
• Learn the industry secrets in EJB scalability.

This course is intended for intermediate to advanced Java programmers. System architects will find the advanced concepts especially beneficial in designing a framework.

• Good understanding of Object Oriented Programming using Java
• Have some experience of using IBM VisualAge for Java in Java application development
