Overview
This course will integrate a combination of instructor-led discussions and interactive workshops to demonstrate the development and testing of server-side applications using J2EE component model. This course will focus on illustrating the use of the Rational Application Developer product for developing servlets, filters, JavaServer Pages, custom JSP tags, JavaBeans, XML deployment descriptors, MVC concepts, Struts and Enterprise JavaBeans. Additionally, the role of the WebSphere Application Server v6.0 for testing, use of WAR and EAR files, debugging and deployment will be highlighted. Each student will learn the best practices solution for developing J2EE applications using Model-View-Controller framework and the separation of J2EE components.
Prerequisites
Each student should have a basic understanding of the internet and have been exposed to the Java programming language.
Class Format
Lecture and Lab
Audience
Java developers, web page designers and other professionals that will be designing, developing and implementing large scale applications using JSPs, servlets, Enterprise JavaBeans using Rational Application Developer v6.0.
