Overview of SOA

• Exposing business assets as services
• Creating services bottom-up
• Communication between services through standards
  based meta-data
• Composing services through aggregation
• Orchestrating services through flows

4
SOA, XML and Web Service

• SOA can be built on any distributed architecture
  CORBA, DCOM, etc though
• XML and Web Services has emerged as platform of
  choice for SOA

Developing a Web Service

• Lets look at what is involved in building a Web
  Service

Invoke Service
Find Service
Introspect and Bind

• UDDI
• WSIL

• WSDL
• WS-SecurityPolicy
• WS-Policy

• SOAP
• MTOM
• WS-ReliableMessaging
• WS-Addressing

JBuilder and Web Services

• History
• Very early support for Web Services
• Until recently, a wizard-based approach
• Now the Web Services Designer

12
Web Services Designer

• Design goals
• Visual Designer for Service and Flows
• Central cockpit for all things Web Services
• Unified look and feel encapsulating nuances of
  each implementation
• Maintain a pluggable toolkit neutral architecture
  

13
Web Services Designer

• Architecture
• Built on a pair of descriptors Service Designer
  and Flow Designer
• Designed to allow aggregation and collaboration
  between modules
• Pluggable toolkit support
• Built-in support for
• Axis
• WebLogic
• Other Toolkit implementations are welcome

14
Developing Web Services in JBuilder

• Using WSD to build Web Services
• Java based services
• WSDL based services
• Session-bean based services
• Message-driven-bean based services
• Web Services Explorer
• TCP monitor
• WS-I tools
• WSDL Analyzer
• Monitor and Log Analyzer

15
Commonly encountered issues

• Collection classes
• Logging
• Document literal
• Wrapped
• Attachments
• Session

16
WSD Demo

• Lets get started using WSD
• Before each demo, we will
• Start by specifying what we want to do
• A brief how to cheat sheet
• Demo

17
WSD Demo

• Java based service
• Create a bean
• Export it as a Web Service
• Build to generate Web Service stubs
• Run the Web Service on the Server
• Run the Test client to verify service
• A look under the hood

18
WSD Demo

• TCP Monitor
• Configure TCP Monitor
• Monitor SOAP packets on the wire
• Modify and re-execute Service from Monitor
• Save Monitor output

19
WSD Demo

• Complex types Collection Classes
• Introduce complex type in Bean and look at
  type-mapping
• Monitor and look at SOAP
• Create bean with Collection class
• Configure Extra classes
• Get data from Collection

20
WSD Demo

• WSDL styles
• RPC / Encoded
• Document / Literal
• Wrapped
• Document vs. Wrapped

21
WSD Demo

• WS-I Conformance
• Now, lets Create a doc / literal service
• Use WS-I to validate WSDL
• Setup WS-I monitor for logging
• Run Server, test Client
• Validate using WS-I analyzer

22
WSD Demo

• Attachment
• Interoperability issues
• WS-I Basic Profile and attachments
• Soap with Attachments
• DIME
• Base64
• MTOM

23
WSD Demo

• Axis WSDD Flow Designer
• What is WSDD?
• The Flow Designer
• Create a log handler
• Drag Drop handler for Service
• Run Server and run test Client
• Validate logging

24
WSD Demo

• WSDL based service
• Web Services Explorer
• Create Client
• Run Test client
• Use TCP Monitor

25
WSD Demo

• Publishing a service
• Create the service
• Setup the publishing context
• Publish the Service
• Use it to import the Service

26
WSD Demo

• Session-bean based service
• Create Session bean
• Drag, Scan, Create session bean based service
• Run Server, test client

27
WSD Demo

• Message-driven-bean based service
• Create Message-driven bean
• Drag, Scan, Create Message-driven bean based
  service
• Run Server
• Use Web Services Console

28
