J2EE Programming using Eclipse and JBoss

This course teaches programmers how to write enterprise applications based on the Java 2 Enterprise Edition (J2EE) architecture. In addition to the core concepts of J2EE, this course provides specific instruction on building J2EE applications using the best practices established in the field.

After completing this course, the student should be able to:
• The core concepts of J2EE: Servlets, Java Server Pages, Enterprise Java Beans
• How to develop and maintain J2EE applications
• How to deploy J2EE applications into an Application Server
