JBoss ESB

Overview

JBoss Enterprise Service Bus (ESB) provides a service-oriented architecture (SOA) platform to integrate business components and services into automated business processes. This course covers the JBoss ESB 4.2 and its various services, including: registries, transformation services, routing, web services, rules services, and service orchestration.  

JBoss ESB training is targeted at system architects and application developers, with some experience with Java and messaging technology, who want to use the JBoss ESB to create and / or integrate applications using a service oriented architecture.

Prerequisites

• Basic Java competency
• Some understanding of messaging and message oriented middleware
• Some understanding of Web services and related standards (SOAP, WSDL)
• No Java EE specific experience is required for the course, but students who need to know how to integrate with Java EE will obviously need appropriate experience

Course Outline

SOA and ESB
This module introduces the concept of a Service Oriented Architecture, providing a definition of SOA, along with describing the characteristics of a service, and the requirements for messaging and an Enterprise Service Bus.

ESB Overview
This module provides an overview of the JBoss ESB, including ESB Concepts (including providers, services, actions, gateways), example configurations, features, etc.

Custom Action Programming
This module describes the differences between an ESB aware and non aware client, and how to create and configure custom actions.

Transformation Services
This module discusses the Smooks transformation service manager. It covers the Smooks action configuration for both non-profile as well as profile-based configurations. Several action configurations are reviewed, as well as the associated Smooks resource configurations. Out-of-the-box transformations are also covered.

Routing
This module discusses various routing patterns, in particular those implementable with a content based router. The JBoss ESB content based router is discussed, along with a quick introduction to JBoss Drools, on which it is based. The configuration and rules for several routing patterns are reviewed as well.

Web Services
This module describes JBoss ESB support for Web services. It begins with a quick review of Web Services standards, and then discusses JSR-181 Annotations. The main topic are then covered in detail, which are the configuration on Inbound / Producer and Outbound / Consumer web services on the ESB.

Rule Services
This module provides an introduction to JBoss Drools and how to configure rules as services on the ESB. Design issues such as stateful vs stateless, rule authoring language choices, and rule deployment are also discussed.

Orchestration
Orchestration of services is a very important aspect of a service oriented architecture. This module review two orchestration options: jBPM JPDL and WS-BPEL. An introduction to jBPM is provided, along with a quick overview of the WS-BPEL specification.
