3 Siebel Web Service - Introduction Web Services evolved from previous technologies that served the same purpose such as DCOM , CORBA,JAVA RMIWeb Services were intended to solve these problems:InteroperabilityFirewall traversal & Proprietary protocolsComplexitySiebel 8.0 plans to build on the extensive business process automationcapabilities of Siebel 7—which includes Siebel Workflow, Siebel State Model,and iHelp—with two new modules:Siebel Workflow Tasks is intended to extend business processautomation across the“last mile” directly to the point of user interaction. Siebel Workflow Tasksare multiple-step, interactive operationsthat can include branching and decision logic.A new wizard-like user interface is planned,that guides the user through task execution,allows navigation both back and forward within task execution, and enablestask execution to be paused and resumed at any point.
4 Siebel Web Service - Evolution Reasons. InteroperabilityDCOM applications - Windows operating SystemRMI - Java Programming languageFirewall and Proprietary protocolsDistributed systems such as CORBA and DCOM used non-standard portsCORBA uses IIOP which is not practical for Inter-enterprise IntegrationWeb services use HTTP as a transport protocol and most of the firewalls allow access through port 80(HTTP)Complexitywe 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 supportinteroperable Machine to Machine interaction over a network.Web services are frequently just Web APIs that can be accessedover a network, such as the Internet, and executed on a remotesystem hosting the requested services.sharper user interface. New colors, fonts, and iconsA dedicated side bar is expected to provide immediate access tofrequent actions and information the user needs,including enterprise search, links to thenew Siebel 8.0 Task Based User Interface, and iHelp.
6 Siebel 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 - Simple Object Access ProtocolAn XML envelope for XML messaging , Header + BodySOAP 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:Envelopexmlns:soap=“soap:encodingstyle=<soap:Body xmlns:m=“<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:Envelopexmlns:soap=“soap:encodingstyle=<soap:Body xmlns:m=“<m:GetWeatherResponse><m:Degree>-5</m:Degree></m:GetWeatherResponse></soap:Body></soap:Envelop>
10 Siebel Web Service - 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”/><portType name=“Weather”><operation name=“GetWeather”><input message=“GetWeatherRequest”/><output message=“GetWeatherResponse”/></opertion></portType>
11 Siebel Web Service - 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 Now we come to our new definition to describe the web service asAn application component thatCommunicates via open protocols (HTTP,SMTP , etc)Processes XML messages frames using SOAP.Describe its messages using XML schemaDescribe itself using WSDL.Find and bound using UDDI.
14 Siebel Web Services - Inbound Web Service Inbound: Enable an external system to access Siebel data, business services, and workflow processesSiebel application as a service (called by an external system)Typical Siebel Inbound webservice works as follows.Siebel ApplicationExternal SystemWBIWBI
15 Siebel Web Services - Inbound Web Service Exposing a Siebel Business Service/WFas a Web ServiceLogin 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 port list 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 record for the new service port you createdEnter the name of the web service operation.Select the name of the business service method in the method Display 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 communicationImport 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 definitionyou have to import the runtime information generated in 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 Services Administration view.Click Import to display the EAI Web Service Import dialog box and specify the export file (.xml) created from 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 actionsAgents - 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 areLoosely coupled pieces of application functionalitypublishedconsumedcan be combined with other applications over a network.Web ServicesStack of emerging standards.Define protocols.Create a loosely coupled framework for programmatic communication among disparate systems.
