Introduction to Enterprise JavaBeans (EJB) 3.0

Introduction to Enterprise JavaBeans (EJB) 3.0 introduces the experienced Java developer to Enterprise JavaBeans — the Java EE standard for scalable, secure, and transactional Java components. EJB 3.0 has reinvigorated this area of Java enterprise development, with dramatic improvements in ease of use and smooth integration with servlet-based or JSF web applications. This course provides a few notes on 2.1 compatibility but focuses on the 3.0 specification and doing things the 3.0 way. Students get an overview of the EJB rationale and architecture, and then dive right into creating session beans and entities. The new dependency-injection features of EJB 3.0 cause perhaps the most confusion, so we work through a chapter devoted explicitly to DI and JNDI, and basically how components find each other to make an application. We then study entities and the Java Persistence API more deeply, and get a look at message-driven beans as well.

Java EE

The Java EE Bootcamp provides a hands-on introduction to the primary technologies used in modern-day Java EE development. Specifically, this course covers the technologies in the presentation tier (HTML, JSP, and JSF), the business tier (JavaBeans and Enterprise Java Beans), and the integration tier (Enterprise Java Beans, JNDI, JPA, etc.) of Java EE development. The course begins with an introduction to web development using HTML and JSPs, providing the foundational information required to learn JSF. The next two days of the course focus on rich web-development using JSF components. Address the business tier and the integration tier by examining the EJB 3.0 technologies.

Advanced JavaServer Faces (JSF)

Advanced JavaServer Faces (JSF) is an extension of the Introduction to JSF course, adding a two day-module on advanced techniques focused on custom component libraries, JavaScript, and Ajax. Proceeding from a foundation of Java, Servlets, and JSP, the course develops the best-practice concepts of MVC architecture and command-object encapsulation that propel the JSF architecture. Students create JSF web applications by organizing their pages as JSF component trees, and their server-side code as JSF managed beans and controllers. They add data-conversion and validation logic and learn to work with JSF’s data-table control. Then, we change our perspective a bit and start thinking in terms of reusable component libraries — using them and also developing them. Custom components prove to be the ideal delivery vehicle for JavaScript in JSF applications, and ultimately serve as the backbone of a robust Java/Ajax architecture. We work with two popular component libraries along the way — Tomahawk and RichFaces — and also get a look at Direct Web Remoting, or DWR.

It’s a dynamic and competitive world with full of ups and downs in IT sector and therefore; the fresh engineers require just more than theoretical knowledge to get themselves ready for the industry. Academic institutions across the world provide the basic and conceptual fundamentals covering multiple areas in computer science. With increasing number of graduating engineers, but with constant number of companies, it becomes difficult for fresh engineers to compete with their unpolished skills because they need more effective and specialized quality training.
