Introduction

•  IBM Integration Bus v9 adds new support to simplify connectivity with IBM BPM v7.5.1, v8.0.x and v8.5

•  Works with BPM Express, Standard and Advanced

•  Scenario: ‒  Business Analyst is developing a Business Process Design ‒  BPD needs some business data from an external corporate service ‒  Business Analyst knows the data he needs but not the connectivity

steps needed to get it

•  Allows the BPM developer to concentrate on Human Task Processing by delegating connectivity configuration to the IBM Integration Bus developer

•  Assumes a top down approach from the BPM perspective


Agenda

•  Overall approach ‒  Products and terminology ‒  How the BPM developer and the IIB developer interact

•  BPM development view ‒  How the BPM developer sets up their process design and supplies their

specification to the IIB developer

•  IIB development view ‒  How the IIB developer uses the BPM specification to create an appropriate IIB

integration service ‒  How the IIB developer supplies the integration service connection information

back to the BPM developer

•  BPM testing ‒  How the BPM developer incorporates the IIB connection into their process

design and tests it

•  BPM Advanced Integration with SCA


The Products

•  What does IBM BPM Standard provide? ‒  Business Process Design (human tasks plus system tasks),

management and administration Ø Business Process Designer Ø Business Process Center Ø Process Server

•  What does IBM Integration Bus provide? ‒  IIB is the new name for WebSphere Message Broker ‒  Connectivity, Integration and Transformation Ø IIB Toolkit Ø IIB Node

Terminology

•  BPM Process Center – Repository for all BPM artifacts

•  BPM Process Designer – GUI tool used to build Business Process Designs (BPD)

•  BPM Integration Service – A type of System Activity called from a BPD used to integrate with external entities

•  BPM Toolkit – BPM Process Designer artefact container, effectively a library

•  Snapshot – A particular version of a BPM Toolkit

•  TWX file – A file format used to export a snapshot of a BPM Toolkit

•  IIB Toolkit – GUI tool used to build IIB flows

•  IIB Integration Service – A SOAP bound Web Service hosted by IIB broker run time


The Problem

•  The corporate service ‒  May use any transport type ‒  May supply more data than is required ‒  May require security, QoS, ...

•  The Business Analyst ‒  Knows the input/output Business Objects required for the Business

Process Design ‒  Does not want to know how to configure the transport or

transformation

design and tests it



Create Business Process Design

•  Define the human tasks and system tasks in the process flow

•  Define Business Objects to be used by the flow

•  For each task define and map the variables

•  Choose to implement the system task as a new BPM Integration Service

Implemented as Integration service GetBalance


Create new BPM Integration Service

•  The BPM developer does not attempt to implement the Integration Service


Define BPM Integration Service Interface

•  Assign Input and Output variables for the Integration Service


Move the Integration Service to a BPM Toolkit

Moving an Integration Service to a Toolkit automatically creates a new Snapshot


Export the BPM Toolkit Snapshot as TWX file

•  The BPM developer now gives the TWX file to the IIB developer so that they can start to implement an IIB Integration Service ...


Agenda








design and tests it



•  WMB v8 introduced the concept of an ‘Application’ ‒  A container for all resources required for a particular solution ‒  Typically comprises several message flows and associated message models ‒  Independently deployable, isolated from other Applications

•  WMB v8.0.0.1 introduced the concept of a ‘Service’ ‒  An Application with a well-defined interface and structure (WSDL). ‒  A container for the resources for a Web Services solution. ‒  Renamed in IIB v9 to ‘Integration Service’

•  An Integration Service has a binding ‒  SOAP 1.1 HTTP binding by default ‒  Each Operation is implemented by a separate sub-flow. ‒  It has sub-flows to handle exceptions from the input node.

•  Create an Integration Service … ‒  From scratch ‒  By importing a WSDL file ‒  By importing a BPM TWX file

What is an IIB Integration Service?


Generate the IIB Integration Service from TWX

•  There are several ways to initiate Integration Service generation in the IIB Toolkit if you have a TWX file

1.  From the Quick Start screen

2.  From File → New → Service

3.  From the Patterns Explorer


From Quick Start

•  Browse to the TWX file

•  Select the BPM Integration Service

•  Provide the IIB Integration Service name


From File → New → Service

•  Provide an IIB Integration Service name

•  Select Create a new service interface from an IBM BPM integration Service

•  Browse to the TWX file



From Patterns Explorer - 1

•  Create New Instance

•  Provide Instance name



•  Need to Configure Pattern Parameters

•  First browse to the TWX file


•  Next provide a new IIB Integration Service name



•  Generate the IIB Integration Service


Explore the IIB Integration Service - 1

•  A WSDL is generated to represent the Integration Service with a namespace derived from the BPM Toolkit name

•  SOAP 1.1 HTTP binding with URL suffix based on the BPM Integration Service name

•  One operation with name based on the BPM Integration Service name

•  An overall message flow is generated with sub-flow to handle exceptions from the input node and a placeholder for an operation sub-flow

•  The IIB developer is responsible for creating the operation sub-flow

•  XML Schemas are generated to represent the Business Objects with a namespace derived from the BPM Toolkit name

Implement the IIB Integration Service

•  Click on the operation in the service editor to open the sub-flow and allow implementation

•  This is where IIB can transform the request message, connect to the corporate Systems of Record (WS, CICS, SAP, MQ, DB, .NET ...) and transform the returned data into a response message ‒  For example, could call a .NET assembly for a Windows-based service

IIB developer implements the service by adding node(s) to process the request and produce a response message


Deploy and Test the IIB Integration Service

•  Deploy the Integration Service to a IIB broker runtime and test

•  The deployed Integration Service will have an endpoint URL and a query WSDL (?wsdl) URI ‒  These will be used by the BPM Integration Service

•  Once the IIB Integration Service is working as required, information about how to access it must be passed back to BPM


Export the IIB Integration Service to a TWX file - 1

•  Export the service information by right clicking the Service Description

•  The export wizard first allows the host name and port of the deployed service be specified


Export the IIB Integration Service to a TWX file - 2

•  Specify the snapshot name, which defines the version of the BPM Toolkit

•  Specify where the TWX file will be written

•  The resultant TWX file can now be handed back to the BPM developer


Agenda








design and tests it



Import the New TWX file

•  Import the new snapshot of the Toolkit from the TWX file via BPC


Update the BPM Toolkit Dependency

•  In Process Designer return to the Process Application that references the Toolkit

•  An icon will show that the Toolkit has a new snapshot and can be upgraded

•  Select to update the dependency


Explore the BPM Integration Service - 1

•  A Web Service Integration has been added to the Integration Service, thereby implementing it

•  Data mappings have been done between Integration Service variables and operation variables


Explore the BPM Integration Service - 2

•  The WSDL URI, operation and Endpoint Address URL have been set

•  Environment variables have been used in the Endpoint Address URL so that they can easily be changed if the IIB Integration Service is moved


Test the BPM Process Design

•  The BPM Integration Service can be tested by executing the BPD using the Playback Server

•  Start the Playback

•  Execute each task to complete the flow


Agenda








design and tests it



•  IBM Integration Developer is the integration tool that you use to author SOA-based services and choreograph them into business processes that you can deploy on BPM Advanced.

SCA Request node -  Send outbound synchronous request messages to BPM. -  The node blocks for a specified period until a response is

received. -  Used for sending one-way outbound messages.

SCA Input and SCA Reply nodes –  Receive inbound messages from BMP Advanced. –  A BPM SCA Import component can use Message

Broker as an SCA endpoint.

SCA Async Request & SCA Async Response nodes

-  Send outbound asynchronous request messages to BPM.

-  IIB can carry on processing after request has been sent.

-  Async Response Node listens on a different thread.

The SCA nodes support Web Services and MQ bindings.

IIB Wizards


To build this, you can start from IID . . .

1. Develop Business Process Application in IID first.

2. Export Project Interchange (PI) file.

3. Import PI into IIB to create message model and Broker SCA Definition.

4. Create message flow using the Broker SCA Definition.


Or you can start from IIB . . .

1.  Generate Broker SCA Definition from Message Set in IIB.

2.  Develop Message Flow using Broker SCA Definition.

3.  Export SCA components, XSDs and WSDL from Broker SCA Definition.

4.  Import SCA Components, XSDs and WSDL into WID.

5.  SCA components are automatically created in the Assembly Diagram. Data types and interfaces are automatically added to the module.
