Developing Applications with Java EE Course Overview

The Developing Applications with Java EE course introduces delegates to version 5 of the Java Enterprise Edition API.  It explains the JEE technologies and how they can be used to build large scale web based applications.

Delegates will learn how to develop Java systems that generate front end web pages using tools such as Servlets, Java Server Pages and Java Server Faces and will also create business components using EJB version 3.0.  In addition, we will develop programs to access remote databases and show how technologies such as JNDI, JMS and Web Services can be integrated into the overall solution.

Skills Gained

The delegate will practice:

• JDBC
• Remote Method Invocation
• Servlets
• Java Server Pages
• Java Server Faces
• The Java Persistence API
• Java Messaging Services
• JNDI
• Java Transaction API
• Enterprise Java Beans 3.0
• Web Services

Who will the Course Benefit?

The Developing Applications with Java EE course is aimed at programmers who need to understand and program in the Java enterprise architecture.

Course Objectives

By the end of the course delegates should be able to:

• Understand the Java Enterprise Architecture
• Write java programs to interface with databases
• Run method calls on remote objects
• Write code to generate dynamic HTML pages
• Create web applications using Servlets
• Use tag libraries to develop Java Server Pages
• Investigate web applications using Java Server Faces
• Configure the Java Messaging Service
• Understand the Java Naming and Directory Interface
• Create business components with the EJB specification
• Use the Java Persistence API to create entity classes
• Scope transactions with the Java Transaction API
• Write web services

Requirements

A pre-requisite for the Developing Applications with Java EE course would be JVP - Java Programming or relevant experience with Java.
