Siebel Web Services - Agenda

• - Introduction
• Basic Evolution
• Web Service Components
• SOAP
• WSDL
• UDDI
• - Siebel - WebServices
• Inbound Web Service (Exposing BS/WF as a WS)
• Outbound Web Service (Publish external.wsdl in
  Siebel e.g.. Google.wsdl)
• - SOA
• What is SOA?
• Difference between OOP SOA
• Relation between SOA Web Services

Siebel Web Service - Introduction

• Web Services evolved from previous technologies
  that served the same purpose such as DCOM ,
  CORBA,JAVA RMI
• Web Services were intended to solve these
  problems
• Interoperability
• Firewall traversal Proprietary protocols
• Complexity

4
Siebel Web Service - Evolution
Reasons.

• Interoperability
• DCOM applications - Windows operating System
• RMI - Java Programming language
• Firewall and Proprietary protocols
• Distributed systems such as CORBA and DCOM used
  non-standard ports
• CORBA uses IIOP which is not practical for
  Inter-enterprise Integration
• Web services use HTTP as a transport protocol and
  most of the firewalls allow access through port
  80(HTTP)
• Complexity
• we can implement web service with our existing
  language and existing operating system.

5
Siebel Web Service - Definition

• What is a Web Service?
• Web Services is a software system designed to
  support
• interoperable Machine to Machine interaction over
  a network.
• Web services are frequently just Web APIs that
  can be accessed
• over a network, such as the Internet, and
  executed on a remote
• system hosting the requested services.

6
Siebel Web Service - Components

• Web Service Components.
• SOAP An XML-based, extensible message envelope
  format, with "bindings" to underlying protocols
  (e.g., HTTP, SMTP and XMPP).
• WSDL An XML format that allows service
  interfaces to be described, along with the
  details of their bindings to specific protocols.
  Typically used to generate server and client
  code, and for configuration.
• UDDI A protocol for publishing and discovering
  metadata about Web services, to enable
  applications to find Web services, either at
  design time or runtime.
• WS-Security Defines how to use XML Encryption
  and XML Signature in SOAP to secure message
  exchanges.
• WS-ReliableMessaging A protocol for reliable
  messaging between two Web services.
• WS-Reliability An OASIS standard protocol for
  reliable messaging between two Web services.

Siebel Web Service - SOAP

• SOAP.
• SOAP - Simple Object Access Protocol
• An XML envelope for XML messaging , Header Body
• SOAP is an XML Vocabulary standard to enable
  programs on separate computers to interact across
  the network.
• SOAP is not bound to any particular protocol
  such as HTTP , SMTP or even TCP/IP.
• Structure of SOAP.
• A required envelope element that identifies the
  XML document as a SOAP message.
• An optional Header element that contains Header
  Information.
• A request Body element that contains call and
  response information.
• An optional Fault element that provides
  information about errors that occurred while
  processing the message.

Siebel Web Service - SOAP Request

• Example of SOAP request.
• ltxml? Version1.0?gt
• ltsoapEnvelope
• xmlnssoaphttp//www.w3.org/2001/12/soap-e
  nvelope
• soapencodingstylehttp//www.w3.org/2001/12
  /soap-encodinggt
• ltsoapBody xmlnsmhttp//www.weather.com/wr
  gt
• ltmGetWeathergt
• ltmpostalcodegt44087gtlt/mpostalcodegt
• lt/mGetWeathergt
• lt/soapBodygt
• lt/soapEnvelopgt

Siebel Web Service - SOAP response

• Example of SOAP response.
• ltxml? Version1.0?gt
• ltsoapEnvelope
• xmlnssoaphttp//www.w3.org/2001/12/soap-e
  nvelope
• soapencodingstylehttp//www.w3.org/2001/12
  /soap-encodinggt
• ltsoapBody xmlnsmhttp//www.weather.com/wr
  gt
• ltmGetWeatherResponsegt
• ltmDegreegt-5lt/mDegreegt
• lt/mGetWeatherResponsegt
• lt/soapBodygt
• lt/soapEnvelopgt

Siebel Web Service - WSDL

• WSDL
• WSDL stands for Web Service Description Language.
• WSDL is an XML vocabulary to describe Web Service
  and their capabilities , in a standard manner.
• WSDL specifies what a request message must
  contain and what the response message will look
  like in unambiguous notation.
• In additional to describing message contains ,
  WSDL defines where the service is available and
  what communication protocol is used to talk to
  service.
• WSDL example
• ltmessage nameGetWeatherRequestgt
• ltpart namepostal code type xsstring/gt
• ltmessagegt
• ltmessage nameGetWeatherResponsegt
• ltpart nameDegree type xsstring/gt
• ltmessagegt
• ltportType nameWeathergt
• ltoperation nameGetWeathergt
• ltinput messageGetWeatherRequest/
  gt
• ltoutput messageGetWeatherResponse
  /gt
• lt/opertiongt
• lt/portTypegt

11
Siebel Web Service - UDDI

• UDDI
• UDDI stands for Universal Description , Discovery
  Integration.
• A project to encourage interoperability and
  adoption of webservices.
• Similar to a Universal phone book.
• Specification to publish and discover web
  services in the web.
• Shared Distributed registry on the web.
• Enables three basic functions.
• Publish function(how a web service registers)
• Find Function (how a client finds a web service)
• Bind Function (how the client connects and
  interacts with a web service)

12
Siebel Web Service - Defined As

• Web Service
• Now we come to our new definition to describe the
  web service as
• An application component that
• Communicates via open protocols (HTTP,SMTP , etc)
• Processes XML messages frames using SOAP.
• Describe its messages using XML schema
• Describe itself using WSDL.
• Find and bound using UDDI.

Siebel Web Service - Architecture
14
Siebel Web Services -
Inbound Web Service

• Inbound Enable an external system to access
  Siebel data, business services, and workflow
  processes
• Siebel application as a service (called by an
  external system)
• Typical Siebel Inbound webservice works as
  follows.

Siebel Web Services - Inbound Web Service

• Exposing a Siebel Business Service/WF
• as a Web Service
• Login to Client.
• Click View -gt Site Map -gt Web Services
  Administration -gtInbound Web Services.

  an Inbound web services record
• Enter the namespace for your organization's web
  services.
• Enter the name of the web services in the name
  column.
• Select the Active in the status field.
• Create an Inbound service port record in the
  service portlist Applet.
• Click New and enter the name of the port in the
  Name Column.
• Pick the type of object published.
• Enter the address appropriate for the transport
  chosen.
• Select the protocol or transport that will
  publish the web service.

Siebel Web Service - Outbound

• Step For Siebel Web Services - Outbound
  communication
• Import the WSDL file in Siebel tools.
• Start Siebel tools.
• Choose File gt New Object to display the New
  Object Wizards.
• Select the EAI tab, select the Web service icon,
  and click OK.The WSDL import Wizard appears.
• Setup the Outbound Webservice definition
• you have to import the runtime information
  generatedin the .xml file though the WSDL Import
  Wizard.(OR)
• In the Siebel client, navigate to the Web
  Services Administration view via Site Map.
• Select Outbound Web services from the Web
  ServicesAdministration view.
• Click Import to display the EAI Web Service
  Import dialog box and specify the export file
  (.xml) createdfrom the WSDL Import Wizard in
  step.Click Import.
• Check that the Service Ports section in the
  Outbound Web Services view is populated from the
  export file.
• Make sure Web service status is Active

17
Siebel Web Service - SOA

• What is SOA ?
• Service - Oriented Architecture (SOA)
• Agents (Software or human)
• Emphasis on actions
• Agents - to - agent interaction through message
  exchange.
• A Service is a set of actions that form a
  coherent whole from the point of view of service
  providers and service requesters.
• Service-Oriented Architecture are more suitable
  for loosely coupled distributed applications (Web
  service Architecture)
• Object - Orientation encourages closely coupled
  distributed applications( I.e., CORBA,DCOM,etc.)

19
Siebel Web Service - SOA

• What is relation between SOA Web Services?
• Service - Oriented Architecture are
• Loosely coupled pieces of application
  functionality
• published
• consumed
• can be combined with other applications over a
  network.
• Web Services
• Stack of emerging standards.
• Define protocols.
• Create a loosely coupled framework for
  programmatic communication among disparate
  systems.
