Description
This first course in the series provides the foundation for the rest of the course series. It introduces learners to the Java 2 Platform, Enterprise Edition and to Enterprise JavaBeans. It describes the features and benefits of the J2EE application model and its JavaBeans component model. It also covers the EJB architecture, client, and classes and interfaces.
Audience
The intended audience for this course are system administrators, application developers, system analysts, software engineers, and programmers/analysts. Learners should be experienced with object-oriented design and the Java programming language. It would be helpful for learners to be familiar with distributed programming (multi-tier architecture), relational or object database programming, transactions, and component technology.
