This is the simplified flow for a typical message entering the AE from the IS. Communication between the IS and AE is done using the XI-protocol (SOAP w/ attachments) over HTTP(s).
Upon arrival in the J2EE engine the message is queued and persisted as appropriate. These services are provided by the messaging layer.
The message goes through a series of modules (generic and specific, possibly custom written).
The message is posted to the backend application using the appropriate native protocol The core services provided by the AF (described in the previous slide) are leveraged throughout the joutney of the message in the AE.
The PCK is using the same adapter framework providing core services.Since the PCK is intended to be completely detached from the Integration Server (different business partner), central configuration and adminsitration is not possible.
Therefore the following components have been provided with the PCK Configuration UI (which is really a lean Integration Directory) Monitoring and administration UI.
