This course is targeted at the developer, already familiar with JAVA Servlet programming, with a detailed knowledge of JavaServer Pages. During the course the student will write JSPs and JavaBeans which interact with Servlets and HTTP clients using the Model, View, Control (MVC) architecture.

Pre-requisites

The student should be familiar with Java Programming and Java Servlet Programming. This knowledge can be gained by attending courses EC21, EC22 and EC32.

Course Objectives

This course provides students with the skills to write effective JavaServer Pages and JavaBeans. While covering these in detail, the course retains a ‘high level’ overview of the Design Patterns used for such development. During the course the student will write many of these to ensure that the statements taught are fully understood and practical experience is gained. On completion of this course the student will be able to:

•     code JavaServer Pages
•     access JavaBeans from servlets / JSPs
•     use JSP tags
•     understand JSP JavaBean scopes
•     use JSP forwarding
•     use Model, View, Controller methodologies
•     use JSP error pages
•     use the WebSphere testing environment (if applicable)

Course Environment

Development will be performed using:

•     the Java Development Kit (JDK) plus a text editor
•     JBuilder
•     NetBeans
•     Rational Application Developer
•     Websphere Studio Application Developer
•     Eclipse

Course Format

Practical sessions make up a large part of the course, allowing delegates to demonstrate and reinforce the lectures given. Examples are used extensively, ranging from simple code 'snippets' to full applications with complete ‘real world’ functionality. These are supplied at the start of the course and it is encouraged that the delegates execute and ‘experiment’ with these under the instructor’s guidance as they are introduced. These examples are available to take away, along with the delegate’s own work. The comprehensive Student Guide supplied is fully indexed serving as a useful reference tool long after the course has finished. Delegates will also be able to access a free help-line with technical questions relating to topics covered on the course.
