Service tab

On the Service tab, you enable a Message to be invoked through service requests. Based on one Runtime configuration, external applications use services to handle the Messages. For example, Composition Center uses services to preview and publish document definitions, and Ad Hoc Correspondence and Correspondence Reviewer 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.
Enable service support for content types	Select the preview formats to be available in the application: • application/pdf – Enables paginated preview in Composition Center. • image/tiff – Enables paginated preview in Ad Hoc Correspondence. • text/html – Enables unpaginated (HTML) preview in Composition Center and Ad Hoc Correspondence.
Use default preview connector	Applicable if the expected content type from the preview service request is application/pdf, text/html or image/tiff. Select to use default output connectors for previewing the Message in the external application. The connectors are automatically created and selected at preview service requests. They are not visible in Design Center. The default preview connectors automatically use the required drivers. The drivers are pre-configured with settings that are sufficient for most preview scenarios.
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.
