Training Course Summary:

The Advanced Business Component Development with Enterprise JavaBeans Technology course provides students with the knowledge on how to develop robust back-end functionality using Enterprise JavaBeans (EJB) technology. This course uses an online auction scenario to demonstrate how to leverage container-managed services with entity, session, and message beans to resolve the real-world problems presented by an electronic commerce application. The emphasis of this course is on providing practical EJB technology coding experience, while also covering the designs and best practices used to solve transaction, messaging, security, and legacy integration issues. In addition, this course looks at how EJB technology components can be integrated with web service technologies. The hands-on lab environment uses the Java 2 Platform, Enterprise Edition (J2EE) reference implementation server to provide students with a nonvendor-specific experience.

Pre-Requisites:

To succeed fully in this course, students should be able to:
Display experience with the Java programming language
Display experience of creating simple J2EE applications using session or entity beans (practical experience required, theoretical knowledge would be insufficient) Note: This course assumes basic knowledge of enterprise JavaBean Components such as that provided in the course FJ-310 "Developing Applications for the J2EE Platform."
Display experience with distributed computing concepts in Java technology (Remote Method Invocation [RMI], Java Naming and Directing Interface(TM) [JNDI[TM]] Application Programming Interface [API], Java Interface Definition Language [IDL] technology)
Demonstrate some knowledge of declarative programming concepts used in J2EE technology
Demonstrate some practical experience with a J2EE technology application server

Who Should Attend:
