Lab introduction

Create Web services

Business modeling

Implement a business process

Integrate services through ESB

Lab Scenario

A library application

Book subscription service

– Query whether a book exists in a library

– If it exists, query whether it is allowed to lend out

– If it is allowed to lend, subscript the book

Book query service

– Domestic books and foreign books are in different libraries

– The foreign books is charged in USD

– When query a foreign book, its price should be converted from USD to RMB

Lab Environment

Process modeling

– WebSphere Business Modeler (WBM)

Service integration development

– WebSphere Integration Developer (WID)

Runtime

– WebSphere Process Server (WPS)

– An integration test environment embedded into WID

Create Web services

Create a Web service from a Java Bean

– Create a Web project

– Generate a Web service

Create a Web service from a WSDL

Create a Web service from an abstract WSDL (SCA Interface)

– Obtain a concrete WSDL using WSDL Editor

– Export as a Web service

Test a Web service using Web service explorer

Create a Web service from a Java Bean

Create a Web service from an abstract WSDL (SCA Interface)

Create an SCA module and an SCA component

Export the SCA component and obtain a concrete WSDL

Generate a Web service from the concrete WSDL

Test the Web service

Monitor the SOAP request & response

Create an SCA module

Create a temporary SCA module

Give a name of the temporary module

Create an SCA componentNavigator or package

explorer view

Copy meta data to the TempMod

Create a SCA component

Select an interface for a SCA component

Export the SCA component

Create a SCA export using Web service

bindingA concrete WSDL is

generated

Generate and Test a Web service

Monitor SOAP request & response (1)

TCP/IP monitor is in the Windows-> Preferences menu

Create a new TCP/IP monitor

Host name and port under monitor

1

2

Start the monitor after creating it

3

Monitor SOAP request & response (2)

In Web Services Explorer, change the endpoint port to the local

monitor port (9085)

Monitored SOAP request and response

Service identification and specification

For the book subscription service in slide 3

Service identification

– List candidate processes and services

Service specification

– Service exposure decisions

– Non-functional requirements

– Message specifications

– Other else?

Create a process in WBM

Screen video

Please use a screen resolution over 1280*1024

– Create a business item

– Create a process

– Export the process to WPS

Create a WBM project

WBM Project Name

Directory of business processes

Create a process when creating the project

Create a business item

Create a business item to represent books

Specify book attributes

Create a process (1)

Input to the process is a String (book name)

Query whether the book exists. Its output is a business item (book).

The probability of book found is 50%

Check whether the book is allowed to lend

The probability of book allowed is 50%

Preengage the book

Notify the reader that the book is not allowed to lend

Notify the reader that the book is not found

Create a process (2)

Switch to WPS mode

1Select an output branch

2

Edit attributes of the output branch

3Edit a condition expression

4

Export a process from WBM

Export the process model to WPS

Target directory to keep the exported project

A module project refers to a module library. A library keeps meta data, such as

interfaces, data types

Package the exported export to a zip file

Import a process to WID

Select to import zip packaged projects

Import a SCA module and its library

Simulate a process

Import Web services

Implement Java components

Export the BPEL component

Test a SCA component

Import Web services (1)

Copy the WSDL of the imported Web services into

the SCA module

The two WSDLs are for the Query service (AProject) and Notify

service (BProject)

Import Web services (2)

Drag imported WSDLs to Assembly Diagram to generate Web service

imports

Adjust the assembly diagram, and wire to the Web service imports

Implement Java Components (1)

Select Java implementation

Select Java package

Implement Java Components (2)

Java implementation of the check component Java implementation of the

preengage component

Export the business process

Select Web service binding

Select SOAP/HTTP

Create a mediation module

– Create a mediation component

– Connect to target services

Create a mediation flow

– Create a filter mediation

– Create transformation mediations

Export the mediation component

Test the mediation component

Create a mediation module (1)

Create a mediation module Add an SCA library

Add an import and a Java component

Create a mediation module (2)

Java implementation of Component1

Create a new SDO from a Data Type

Set attributes of the SDO

Create a mediation module (3)

Create a new interface as the unified interface of the mediation

1

The interface is completed2

Add the interface to the mediation component

2

Create a mediation flow (1) Connect interface and references
