This course builds upon the foundations of Java technology and provides a practical overview of EJB covering current and future capabilities. The newest version of EJB, 3.0, may fit green field projects; however, existing application servers rely on earlier versions such as EJB 2.1. This course deals with the topics necessary for real-world EJB application including architectural options for persistence.
Prerequisites: Knowledge of the Java programming language and Object Oriented fundamentals.
Who Should Attend: This course is intended for a more experienced Java programmer. It teaches not only the fundamentals of Java EJB, but also advanced techniques. This course assumes some knowledge of Object Oriented design and a familiarity with UML.
