Overview
This course covers how to program JSF Web Applications, how to use the Spring Framework, and to use the Hibernate Object/Relational Mapping (ORM) framework to implement the persistence layer of J2EE applications to develop flexible, testable and maintainable Java EE web applications. Besides covering each of these technologies individually, emphasis is placed on how to utilize them together.
