Enterprise JavaBeans[tm] Programming

( SL-351 )

Course Description

The Enterprise JavaBeans[tm] Programming course provides students with the information needed to create an Enterprise JavaBeans (EJB [tm]) components that is compliant with Java[tm] 2 Platform, Enterprise Edition (J2EE[tm]) and combine them into robust enterprise applications. Instruction and practical hands-on exercises cover these essential topics: Session and entity beans, the Container framework in which EJB components function, transaction and security management features. Participants use the standard J2EE Reference Implementation server in lab exercises.

Component-based application development increases development productivity through the encapsulation of business logic into reusable components which can be used by the entire development organization. The J2EE technology defines a set of components and builds a service-oriented infrastructure into the platform to automatically support and manage components. At the heart of this specification are EJB technology components.
