Asynchronous Outbound Integration Processing XSL Map Summary The integration framework applies any custom mapping to the publish channel. XSL mapping lets you map user-defined publish channels or customize the mapping done by predefined publish channel processing classes. Both the object structure and publish channel are available. TIP To see if an XSL map exists for a publish channel, go to the Publish Channel tab in the Publish Channel application. Look on the Publish Channel tab for an XSL map. Output The output of this activity must be an XML message in publish channel format. The notation used by the integration framework to represent numbers greater than seven digits is controlled by the mxe.int.usesscientific variable. By default, numbers greater than seven digits use a scientific notation. Send the Publish Channel Data to the External System Summary The following activities take place when the integration framework writes and sends the publish channel data to the external system: 1 The integration framework writes the XML message to the outbound queue specified for the external system. TIP To see which outbound queue an external system uses, go to the System tab in the External Systems application. 2 The cron task that polls the outbound queue picks up the message. 3 The cron task passes the message to a message router. The router uses the endpoint that is associated with the external system, or the publish channel, to identify and to invoke the correct handler. If the publish channel does not have an associated endpoint, the integration framework uses the external system endpoint. TIP To see which endpoint a system uses, go to the System tab in the External Systems application. To see which endpoint a publish channel uses, go to the Publish Channels tab in the External Systems application. To see which handler an endpoint uses, select Add/Modify End Points from the Select Action menu in the End Points application. 4 The processing class that is associated with the handler sends the data to the external system. 54 Integration Guide
