Overview for creating new receiver handlers

The receiver may call the Receiver Framework to invoke receiver handlers at three points during the receiver processing flow (also called as configuration points): preprocessing, sync checking, and postprocessing. These points in the document processing flow are called configuration points. Preprocessing returns one or more receiver documents. Preprocessing may be used to process the document before submitting it to WebSphere Partner Gateway for processing. It may also be used for splitting of incoming document from trading partner. The sync-check handler determines whether the document is to be processed as a synchronous or asynchronous request. Postprocessing provides necessary processing for response documents that are returned from Document Manager as a result of a synchronous request.

The Framework relies on handlers to execute these processing requests. Users may develop handlers to satisfy their specific needs, using APIs that ship with WebSphere Partner Gateway. After you write and deploy the handlers, you need to configure them by using the console. For further information on this process, see the Hub Configuration Guide.
