Developing Applications with Java EE
Course Code: JEE
Duration: 5 days
Developing Applications with Java EE Course Overview
The Developing Applications with Java EE course introduces delegates to the Java Enterprise Edition API, up to version 7. It explains the core JEE technologies and how they can be used to build large scale web based applications. It also includes an overview of Enterprise Java Beans, the Java Persistence API and JEE security.
Delegates will learn how to develop Java systems that create front end web pages using tools such as Servlets, Java Server Pages and WebSocket, and develop back-end components using EJB, CDI and Bean Validation. In addition, we will show how technologies such as JSON, JMS and Restful Web Services can be integrated into the overall solution.
Exercises and examples are used throughout the course to give practical hands-on experience with the techniques covered.
Course Objectives
This course aims to provide the delegate with the knowledge to be able to produce secure, scalable and maintainable enterprise solutions using Java code within the Java Enterprise Edition environment. This incorporates web-based technologies such as Servlets, JSP and WebSocket, via linking solutions like JSON and CDI, to back end architectures using EJB, JMS and JPA.
Who will the Course Benefit?
The Developing Applications with Java EE course is aimed at those who need to develop robust, flexible, extendable and maintainable software using the Java enterprise architecture. Roles include programmers, designers, architects, testers and anyone who needs a good understanding of the Java Enterprise Edition solution.

Adam - Junior Developer - Government
"Trainer did a really good job of getting the information across, in a way which was not boring. His hand-on approach really gelled with the way I like to be trained, and the exercises were a challenge that I found very satisfying and "fun"."
Ben - Head of Development - IT
Very knowledgeable instructor, who shared practical, real-life examples which helped demonstrate principles. Very broad topic, but managed to cover most things and tailored around delegates, which was especially useful.
Ross - Government
Really useful and enjoyable training. The trainer was very knowledgeable and helpful. Would definitely seek training from yourselves in future.
