ABAP Freak Show – June 3rd – Web Dynpro ABAP Notification Service
This episode of the ABAP Freak Show looks in detail at the new Web Dynpro ABAP Notification Service that will ship later this year as part of NetWeaver 7.0 Enhancement Package 2. This technology goes by many names – Long Polling, Reverse AJAX, Comet – but regardless the name the idea is to allow data and updates to appear to be pushed from the server to the client. In this eLearning we look at the infrastructure in ABAP that has been built to support such push without putting too much load on either the client or the server. We also look at implementations of this technology for long calculations, inter-session communication, and asynchronous external communication. We also show a real world example using the ESME application for a real time messaging service built into a business transaction.
