Course Objectives

Students will leave the course armed with the basic skills required to design and build scalable, secure, maintainable web applications - leveraging our extensive experience in the delivery of scalable enterprise applications with complex web interfaces based on JEE technologies.

Throughout this training, students will explore with common web application design problems and given the tools you will need to solve them, such as JEE design patterns. You will also be exposed to a range of JEE and web technologies such as Servlets, JSPs, JSTL and advice on when and how to use them. Students will also learn about the capabilities of servlets, their advantages, servlet architecture, and session management.  Developers will also learn about managing resources, deployment, and application models, how to use custom tags, and how to build robust and capable web applications using servlets and other components.

The course begins with a discussion of web application architecture. A major part of the course is spent on the various web components that are used to implement dynamic web applications. Students will learn not only specific topics and APIs but also how to fit the pieces together into a complete application.  Topics covered include:

  • JEE Application Architecture
  • Servlets
  • Java Server Pages (JSP), EL, and JSTL

 

Course Prerequisites

This is an introductory level training course, designed for experienced OO developers (such as C++ or SmallTalk) that need to extend their skills in web development and understand the basic architecture of a JEE web application and/or implement a web application, taking advantage of what JEE brings to the table.
