Fast Track to Spring 2.x and Spring Web Flow 2

Java Training Overview

Spring is a lightweight Java framework for building enterprise applications. Its Core module allows you to manage the lifecycle of your objects, and the dependencies between them, via configuration metadata (usually XML) and Dependency Injection / Inversion of Control. Its advanced capabilities provide support for JDBC and persistence frameworks like Hibernate (DAO and ORM modules), Aspect-Oriented Programming (AOP module), integration with Java Web technologies (MVC and Web Flow), security, transactions, and more.

This course is a completely new course based on the Spring 2.0/2.5 releases. It starts with the basics of Spring and in-depth coverage on using the powerful capabilities of the Core module to reduce coupling, increase flexibility and ease the maintenance and testing of your applications.

The course goes on to cover all the important capabilities of Spring 2.0/2.5, including using Spring to simplify the creation of a persistence layer with JDBC and/or persistence frameworks like Hibernate, and using Spring's Aspect Oriented Programming (AOP) to program cross-cutting concerns such as transactions and security.

The course includes a brief introduction to Spring's Web MVC, and a thorough coverage of Spring Web Flow 2. Spring MVC is a Web framework based on the powerful Model-View-Controller pattern, and the overview covers the basics of Spring MVC, and how it supports organizing your Web applications in a highly structured, loosely coupled manner. Spring Web Flow 2 is a Spring framework for defining user interface flow in a Web applicaiton. The course includes thorough coverage of Web Flow, including an overview of its capabilities and architecture, defning flows, flow variables and actions, the Unified EL, and flow programming.

The course also includes a brief introduction to Spring Security which was integrated into the Spring project when Spring 2.0 was released. This module includes an overview of the Spring Security architecture, and how to use it to secure both Web application requests and bean invocations

This course is hands on with labs to reinforce all the important concepts. It will enable you to build working Spring applications, and give you an understanding of the important concepts and technology in a very short time.

The standard platform does all labs with the Eclipse IDE and Tomcat, and the lab instructions include detailed directions for programming and deployment. The course is available for all major development environments and application servers, including IBM RAD / WAS.
