Course Overview

Java Enterprise Edition (JEE) is a powerful platform for building web applications. The JEE platform offers all the advantages of developing in Java plus a comprehensive suite of server-side technologies. This course tells you what you need to know to design and build your own web applications. You'll learn the details of the key JEE technologies and how to leverage the strengths of each, with special focus on Servlets and JSPs.  At the same time, you'll be learning about the big picture of JEE and how to design web applications that are robust, efficient, secure, and maintainable. If you want to deliver an application on the web, you'll find this course essential.

Introduction to JEE Web Essentials is a two-day hands-on training course geared for experienced Java developers new to Enterprise Development in Java, who need to get up and running with essential dynamic web development skills. This course provides core JEE knowledge and skills that can be used as the foundation for developing production-quality web applications to a basic level.   

Please note that this class is available in both full day format, amd Mini-Camp Short Course / Flex Hours format. Please see the Public Schedule dates and times below for options.

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

Need different skills or topics?  If your team requires different topics or tools, additional skills or custom approach, this course may be further adjusted to accommodate.  We offer additional Java, JEE and Java for Web application development, design, testing, services, application security and other related topics that may be blended with this course for a track that best suits your needs. Our team will collaborate with you to understand your needs and will target the course to focus on your specific learning objectives and goals.

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.
