Objectives

EJB 3.0 has changed the notion of EJB components as coarse-grained, heavy-weight objects to EJBs as lightweight POJOs with fine-grained annotations. JSF introduced an powerful component based presentation model, that uses POJOs as managed beans and streamlines request handling. In Seam, any class may be an EJB, and can be used as a managed bean for JSF - Seam eliminates the distinction between presentation tier components and business logic components and brings a uniform component model to the EE platform. At the same time, Seam offers a multitude of tools, provides a rapid development framework and features testing support, making the development of Java EE web applications much easier while removing any boilerplate code.

After attending this course, students will be proficient in the use of JBoss Seam to productively develop enterprise applications for the JEE 5 platform.
