Service tab On the Service tab, you enable a Message to be invoked through service requests. Based on one Runtime configuration, external applications (for example, Ad Hoc Correspondence, Correspondence Reviewer, or Composition Center) then use services to create, preview, or release Messages. Depending on the type of service request, the service gateway invokes the correct service. When the Message is service-enabled, internal service input connectors are automatically created at runtime and used for the incoming service requests. The connectors are not visible in the Platform configuration. If the Message is to be paused by an exception rule, for example as for Correspondence Reviewer, you must select the rule resource in the dialog box. Setting Description Service Select to enable a Message to be invoked by service requests. Use default preview connector Applicable if the expected content type from the preview service request is application/pdf or image/tiff. Select to use a default output connector for previewing the Message in the external application. The connector is pre-configured with certain settings (for compression, resolution, etc.) and uses output mode Job. The connector is not visible in the Platform configuration. Service name Enter a descriptive name of the service. The name must be unique within the application domain. Rule Applicable if the Message is to be paused by an exception rule. Select the exception rule resource that pauses the Message. If you select several rule resources, the exception rules are evaluated, one by one, until one rule is evaluated as true or all rules are evaluated. Base service input connector on Applicable for create service requests. Select an existing input connector in the Platform configuration from which the internal service input connectors used at create requests inherit some settings. For example, select an existing input connector and inherit a filter chain with a code page filter from this connector. The filter chain can be applied either directly on the existing input connector, or can be specified per input type in the Project Export Settings dialog box.
