Prerequisites

Attendance on our Java Programming course or an equivalent level of knowledge is essential.

Duration

5 days. Hands on.

Course Objectives

J2EE applications are built using the Model-View-Controller design pattern, with Java Servlets providing the Controller component, while JavaServer Pages support the View component. This course discusses in-depth the servlet technology, and JavaServer Pages as technologies to implement the web interface. This course focuses on these core J2EE technologies, with practical exercises carried out using the Apache Tomcat Servlet Container. At the end of this course, delegates will be able to:

• Understand the implications for implementing the web interface in an MVC design pattern.
• Manage user state with session management.
• Understand J2EE security Discuss relevant Design Patterns.
