Ad Hoc Correspondence and Correspondence Reviewer are web clients, making web service requests to an SSSP (StreamServe Service Provider) application. The SSSP application is the server part of the solution, containing all business logic. The communication between the web clients and the SSSP application is made via a web service API that conforms to the Representational State Transfer constraints (REST API).
The SSSP application accesses the runtime repository using web services, hosted by the service gateway. The communication between the SSSP application and the service gateway goes through a web service API (WS API).
A document displayed in the Ad Hoc or Reviewer application is actually a StreamServe Message, paused by an exception rule before being formatted and distributed.
A paused Message is stored in a Message storage in the runtime repository. In the storage, each Message is identified by a unique Message ID. When displaying a document, the Message ID is used to identify and retrieve the corresponding Message from the storage.
The Ad Hoc, Reviewer, and SSSP applications are accessed from a user interface in the hosting system. For example, a user interface in a business application or a CRM (Customer Relationship Management) system.
