Developing Applications For The Java EE Platform

 

Course Overview

The Developing Applications for the Java EE Platform course provides students with the knowledge to build and deploy enterprise applications that comply with Java Platform, Enterprise Edition 5 technology standards. The enterprise components presented in this course include Enterprise JavaBeans (EJB) technology, the Java Persistence API (JPA), servlets, and JavaServer Pages (JSP) technology, web services, and the Java technology clients that use them. Students gain hands-on experience through labs that build an end-to-end, distributed business application. The labs explore session EJB components, which implement the Session Facade pattern and provide a front-end to entity components using the Java persistence API. The labs also explore message-driven EJB components, which act as Java Message Service (JMS) consumers. Students use web and Java technology clients to access Java technology-based enterprise services using servlets and pages created with JSP technology. Students are taught how to assemble an application from reusable components and how to deploy an application into the Java EE platform runtime environment. The students perform the course lab exercises using the NetBeans(TM) Integrated Development Environment (IDE) 5.5.
