Developing Applications with Java EE - A 5 Day Course

 Open Public Course Closed In-House Course

Course Synopsis

This 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, JSP 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.

The delegate will practice:

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

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
• Use Java Server Faces to product web components
• Configure the Java Messaging Service
• Understand the Java Naming and Directory Interface
• Create business components with the EJB specification
