Transcript SOA Skill Development in 2007

Middleware Technology Training Lab Course
Outline
 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
Outline
 Lab introduction
 Create Web services
 Business modeling
 Implement a business process
 Integrate services through ESB
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 component
Navigator or package
explorer view
Create a SCA
component
Select an interface for a
SCA component
Copy meta data to the
TempMod
Export the SCA component
Create a SCA export
using Web service
binding
A concrete WSDL is
generated
Generate and Test a Web service
Monitor SOAP request & response (1)
1
TCP/IP monitor is in the Windows->
Preferences menu
3
Start the monitor after creating it
2
Create a new TCP/IP monitor
Host name and port under
monitor
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)
Query whether the book
exists. Its output is a
business item (book).
Check whether the book is
allowed to lend
Preengage the book
The probability of book
allowed is 50%
Input to the process is a
String (book name)
Notify the reader that the book
is not allowed to lend
The probability of book
found is 50%
Notify the reader that the book
is not found
Create a process (2)
2
Select an output branch
1
Switch to WPS mode
3 Edit attributes of the output
branch
4
Edit a condition expression
Export a process from WBM
Target directory to keep
the exported project
Export the process model to
WPS
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
Outline
 Lab introduction
 Create Web services
 Business modeling
 Implement a business process
 Integrate services through ESB
Implement a business 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 SOAP/HTTP
Select Web service binding

 Create a mediation module
– Create a mediation component
– Connect to target services
 Create a mediation flow
– Create a filter mediation
– Create transformation mediations
