Business Component Development with EJB Technology, Java EE 5

The Business Component Development with Enterprise JavaBeans Technology training uses an online auction scenario to demonstrate how to leverage container-managed services with session and message beans. Learn how to resolve the real-world problems presented by an electronic commerce application.

Learn To:

• Develop practical EJB technology coding experience.
• Understand the designs and best practices used to solve transaction, messaging and security issues.
• Perform course lab exercises using the NetBeans Integrated Development Environment (IDE).
• Use the Java Platform, Enterprise Edition 5 (Java EE 5) technology, as well as the Java EE 5 SDK.
• Use the Java EE reference implementation server to take advantage of a non-vendor-specific experience.

Live Virtual Class Format

A Live Virtual Class (LVC) is exclusively for registered students; unregistered individuals may not view an LVC at any time. Registered students must view the class from the country listed in the registration form. Unauthorized recording, copying, or transmission of LVC content may not be made.
