  2. 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

  3. 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 interoperableMachine 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.

  7. 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.

  8. Siebel Web Service - SOAP Request • Example of SOAP request. <xml? Version=“1.0”?> <soap:Envelope xmlns:soap=“http://www.w3.org/2001/12/soap-envelope” soap:encodingstyle=http://www.w3.org/2001/12/”soap-encoding”> <soap:Body xmlns:m=“http://www.weather.com/wr”> <m:GetWeather> <m:postalcode>44087></m:postalcode> </m:GetWeather> </soap:Body> </soap:Envelop>

  9. Siebel Web Service - SOAP response • Example of SOAP response. <xml? Version=“1.0”?> <soap:Envelope xmlns:soap=“http://www.w3.org/2001/12/soap-envelope” soap:encodingstyle=http://www.w3.org/2001/12/”soap-encoding”> <soap:Body xmlns:m=“http://www.weather.com/wr”> <m:GetWeatherResponse> <m:Degree>-5</m:Degree> </m:GetWeatherResponse> </soap:Body> </soap:Envelop>

  10. 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 <message name=“GetWeatherRequest”> <part name=“postal code” type =“xs:string”/> <message> <message name=“GetWeatherResponse”> <part name=“Degree ” type =“xs:string”/> <message> <portType name=“Weather”> <operation name=“GetWeather”> <input message=“GetWeatherRequest”/> <output message=“GetWeatherResponse”/> </opertion> </portType>

  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.

  13. Siebel Web Service - Architecture

  14. External System Siebel Application 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. WBI WBI

  15. Siebel Web Services - Inbound Web Service Exposing a Siebel Business Service/WF as a Web Service • Login to Client. • Click View -> Site Map -> Web Services Administration ->Inbound Web Services. • In the Inbound Web Services list applet , Create 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. • In the Operations List Applet ,create a new operation recordfor the new service port you created • Enter the name of the web service operation. • Select the name of the business service method in the methodDisplay name column. • Select the authentication type from the drop-down list. • Generate .wsdl file.

  16. Siebel Web Service - Outbound Step For Siebel Web Services - Outbound communication • Import the WSDL file in Siebel tools. • Start Siebel tools. • Choose File > 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.)

  18. Siebel Web Service - SOA OOPS SOA

  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.
