The Dispatcher component dynamically sets endpoint location properties for outbound messages. It uses the resolution mechanisms registered with the ESB Guidance, which consists of resolvers and adapter providers within the Resolver Framework and the Adapter Provider Framework.

Resolver and Adapter Types

The ESB Guidance includes the following resolvers:

  • WS-MetaDataExchange
  • XPATH
  • STATIC
  • Business Rules Engine
  • UDDI

The ESB Guidance includes the following adapter providers:

  • WCF-WSHttp
  • WCF-BasicHttp
  • MQSeries
  • FTP
  • FILE

The Dispatcher component also uses the Transform libraries that ship with the ESB Guidance to execute BizTalk maps.

Component Properties

The component has three properties:

  • Enable. This property enables or disables the component.
  • EndPoint. This property is a connection string in a format registered with the ESB Guidance, such as in the following example:

    STATIC:\\TransportType=;TransportLocation=https://localhost/ESB.CanadianServices/SubmitPOService.asmx;Action=;EndPointConfig=;JaxRpcResponse=false;MessageExchangePattern=;TargetNamespace=https://globalbank.esb.dynamicresolution.com/canadianservices/;TransformType=;

    WSMEX:\\serverUrl=https://localhost:9904/wsmex;QName={http://globalbank.esb.dynamicresolution.com/canadianservices/}OrderPurchaseWebService

    UDDI:\\serverUrl=https://localhost:9901/rmengine;serviceName=OrderPurchaseWebService;serviceProvider=Microsoft Practices ESB

    UDDI:\\serverUrl=https://localhost/uddi;serviceName=OrderPurchaseWebService;serviceProvider=Microsoft.Practices.ESB

    XPATH:\\TransportType=;TransportLocation=/*[local-name()='OrderDoc' and namespace-uri()='http://globalbank.esb.dynamicresolution.com/northamericanservices/']/*[local-name()='ID' and namespace-uri()='http://globalbank.esb.dynamicresolution.com/northamericanservices/'];Action=;EndPointConfig=;JaxRpcResponse=;MessageExchangePattern=;TargetNamespace=/*[local-name()='OrderDoc' and namespace-uri()='http://globalbank.esb.dynamicresolution.com/northamericanservices/']/*[local-name()='customerName' and namespace-uri()='http://globalbank.esb.dynamicresolution.com/northamericanservices/'];TransformType=;

    STATIC:\\TransportType=WCF-WSHttp;TransportLocation=https://localhost/ESB.CanadianServices/SubmitPOService.asmx;Action=;EndPointConfig=;JaxRpcResponse=false;MessageExchangePattern=;TargetNamespace=https://globalbank.esb.dynamicresolution.com/canadianservices/;TransformType=;

    BRE:\\policy=GetCanadaEndPoint;version=;useMsg=;
  • Transform. This property is either the fully qualified name of a map or a connection string format registered with the ESB Guidance:
    • The following is an example of a map name:

      GlobalBank.ESB.DynamicResolution.Transforms.SubmitOrderRequestNA_To_SubmitOrderRequestCN, GlobalBank.ESB.DynamicResolution.Transforms, Version=1.0.0.0, Culture=neutral, PublicKeyToken=c2c8b2b87f54180a
    • The following are examples of connection strings:

      BRE:\\policy=CanadaSubmitOrderMaps;version=;useMsg=;

      WSMEX:\\serverUrl=https://localhost:9904/wsmex;QName={http://globalbank.esb.dynamicresolution.com/canadianservices/}CanadaSubmitOrderMaps

      UDDI:\\serverUrl=https://localhost:9901/rmengine;serviceName=CanadaSubmitOrderMaps;serviceProvider=Microsoft Practices ESB

      UDDI:\\serverUrl=https://localhost/uddi;serviceName= CanadaSubmitOrderMaps;serviceProvider=Microsoft.Practices.ESB

      XPATH:\\TransportType=;TransportLocation=/*[local-name()='OrderDoc' and namespace-uri()='http://globalbank.esb.dynamicresolution.com/northamericanservices/']/*[local-name()='ID' and namespace-uri()='http://globalbank.esb.dynamicresolution.com/northamericanservices/'];Action=;EndPointConfig=;JaxRpcResponse=;MessageExchangePattern=;TargetNamespace;TransformType=;
