Enterprise JavaBeans Workshop

Case Training
Bristol, Edinburgh, Leeds, London, United Kingdom

Course Format: Classroom | E-learning | Virtual Class | Online | On-site | Blended | Self-paced

Course Description:

'' This course is designed for the developer already familiar with Java Server-side programming looking to gain detailed knowledge of Enterprise JavaBeans (EJB2.0) development

Pre-requisites
The student should be familiar with Java Server side programming using the appropriate IDE (Integrated Development Environment). This can be gained by attending course EC31.

Course Objectives
Whilst covering the basics of the different types of beans and how they are used, this course also aims to give an insight into how they work internally, since this leads to further understanding of why EJB’s are used over existing technologies. Issues such as Security, Transaction Control, Passivation, Resource Pooling and Distributed Objects are discussed. On completion of this course the student will be able to:

Develop EJBs using a choice of IDE (Integrated Development Environment)
Develop Stateless and Stateful Session Beans
Develop Entity Beans with Bean Managed Persistence
Develop Entity Beans with Container Managed Persistence (CMP)
Develop Relationships and EJB QL for CMP beans
Control the Security, Transaction Management and Passivation Characteristics of the Beans
Use an Application Server to deploy and test EJBs and related components
Store and re-access EJBs using a servlet session
Course Environment
Development will be performed using:

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