Click Here for the Outline in PDF Version Course Outline: Introduction to Enterprise Javabeans (3 Days) with Hands-On Labs Learning Objectives Understand the role of Enterprise JavaBeans in enterprise-level systems development, and its relationship to other J2EE technologies such as JSP, servlets, JMS, CORBA, and XML Understand the EJB architecture: the role of the EJB container in mediating contact between the client and the bean, transaction control, authorization control, and the importance of object pooling Understand the development cycle for beans: Java source code and compilation, XML deployment descriptors, EJB compilation and deployment, and use by an application server Understand the role of entity and session beans, their lifecycles and interactions with the container Develop and test BMP and CMP entity beans and understand the importance of each of the entity-bean methods in assisting the container in pooling Develop and test stateless and stateful session beans and effectively manage passivation/activation cycles Use the bean context interfaces to assist with persistence code and to correctly establish bean-to-bean communication This course description should be used to determine whether the course is appropriate for you based on your current skill and technical training needs.

Course Audience This module offers the Java programmer an introduction to the Enterprise JavaBeans (EJB) architecture. EJB’s position at the heart of the Java Enterprise platform and the use of EJB application servers as the backbone of large-scale distributed systems are studied. We consider the advantages of the application server architecture – transaction control, security, persistence, scalability through pooling and clustering – and study the development process for entity and session beans in depth. Course Description The focus for this module is on end-to-end connectivity. The module follows a path roughly from the data layer to the presentation layer, so we look at entity beans first, and work demos and exercises in both Bean-Managed and Container-Managed Persistent Beans. Then the EJB session layer is considered, and both stateless and stateful session beans are developed. As part of the lab work, these are hooked to provided JSPs to illustrate the complete system and typical architecture. This module can be followed by the “Effective EJB” module to complete a student’s understanding of the EJB architecture through study of transaction control, security, performance tuning, and design patterns and strategies. Prerequisites Solid Java programming experience is a must. Our Java Programming course is good preparation for this module. Some experience with distributed systems development, especially object-based systems such as Java RMI, CORBA, or COM is a plus. It is worth emphasizing that students must have strong Java programming experience and be ready to tackle distributed component concepts as well as the very specific demands of EJB syntax.
