What needs to be done?

The solution: SOA and the Enterprise Service Bus

Facilitate application reuse

Decouple interface logic from applications

Detangle point-to-point connections so that any application can talk to any other

Enable applications to communicate with each other regardless of Programming languages System platforms Programming models Connection protocols Data formats

What is an Enterprise Service Bus?An Enterprise Service Bus (ESB) is a flexible connectivity

infrastructure for integrating applications and services.

Shape = Transport protocol

Color = Data format

An ESB performs the following between requestor and service

CONVERTS between different transport protocols

MATCHES & ROUTES communications between services

TRANSFORMS between different data formats

IDENTIFIES & DISTRIBUTES business events


What is WebSphere Message Broker?

Optimized for high-volume processing with a robust set of pre-built mediation function

Enables transformation between a wide range of data formats

• Integrates everything through standard protocols and WebSphere Adapters

Exploits MQ enterprise messaging backbone

An ESB…..

Built for universal connectivity and transformation in heterogeneous IT environments

Change applications with no impact to existing applications

Add new function faster

1. Eliminate point-to-point application connectivity2. Change your I.T. with minimal disruption3. Improve business flexibility4. Reuse services for multiple purposes

Requirements of a Message Broker

Join application and information sources

Heterogeneous

Data matching and routing

Data transformation

Database integration

Transactional

Extensible

Provide a means of implementing a services oriented architecture

Support for standards

Simple to use


WebSphere Message Broker Universal Connectivity

–Simplify application connectivity to provide a flexible and dynamic infrastructure

Routes and transforms messages FROM anywhere, TO anywhere–Supports a wide range of protocols

• MQ, JMS 1.1, HTTP(S), Web Services (SOAP/REST), File, EIS (SAP,SEBL…), TCP/IP…–Supports a broad range of data formats

• Binary (C/COBOL), XML, Industry (SWIFT, EDI, HIPAA…), User–Interactions and Operations

• Route, Filter, Transform, Enrich, Monitor, Distribute, Decompose, Correlate, Detect Simple programming

–Message Flows to describe application connectivity comprising…–Message Nodes which encapsulate required integration logic which operate on…–Message Tree which describes the data in a format independent manner–Transformation options include Graphical mapping, Java, ESQL, XSL and WTX

Operational Management–Wide range of operating system and hardware platforms supported

The Logical Message Model - Addressing

Update NAMESDB with the value of InputRoot.Body.CustomerOrderMessage.Person.name.last

Set the output message OutputRoot.Body.SupplySystemMessage.DespatchTo field to be the value of the input message InputRoot.Body.CustomerOrderMessage.Address

Properties MQMD

IF Body.Person.height > 183 THEN

INSERT INTO Database.TallPeople (Name,Height,Age) VALUES (Body.Person.Name, Body.Person.height, Body.Person.age);ENDIF;

DataInsert

IF (XML format required) THEN OutputRoot.Properties.MessageFormat = 'XML';ELSE IF (custom format) OutputRoot.Properties.MessageFormat = 'CWF';ELSE IF (SWIFT format) OutputRoot.Properties.MessageFormat = 'TDS';ENDIF;

Java Compute

public class jcn extends MbJavaComputeNode {

String personName = (String)assembly.getMessage().evaluateXPath(“/Body/Person/Age”);

Message Processing Examples


Logical Message Model

Many message formats have been already defined

– e.g. MQ, XML, SOAP, MIME, HTTP, SWIFT, ACORD, AL3, EDI-FACT, EDI-X.12, FIX, HL7, HIPAA

…but you can always model your own from within the advanced Eclipse tooling

– either from scratch or by importing C structures, XML schema, COBOL copybooks etc.

Lazy and opaque parsing capability

Broker

Message Broker Toolkit

Standalone runtime environment

Execution groups for isolation and scalability

Many different platforms

Also provides runtime security model and augmented pub/sub

Broker Development and Administration Environment

Based on Rational Application Developer

Windows and Linux

Manages a domain of brokers

Drives deployment

Controls access to domain


Components – Message Brokers Toolkit

Development of broker artefacts

– e.g. message flows and message sets– Stored in a local or team repository

Administration of broker domains

– e.g. deployment and monitoring

Based on Rational Application Developer

– Eclipse 3.0– Windows and Linux platforms– Included Java, XML development

environment– Integrated debugging capability

Repository


Simple steps to run what I developed

The various artifacts we have developed must be grouped together for deployment

A Broker Archive file is used for this purpose

The .bar file is created, populated and then deployed to the desired Broker

The Toolkit passes this deployment request to the Config Manager who communicates with the targeted Broker

Broker.barfile
