TechEd is quickly approaching and I thought I would use this episode of the ABAP Freak Show to preview some of the Web Dynpro ABAP related sessions that will presented at TechEd. I preview the following sessions in this video:
This episode of the ABAP Freak Show looks in detail at large database objects – STRINGS and RAWSTRINGS. Although we have had the ability to use unlimited length STRING and RAWSTRING fields in database tables in ABAP since WebAS 6.10, NetWeaver 7.0 Enhancement Package 2 brings several new features which help to optimize access to these fields. In this eLearning we study both the new Locator and Stream object for reduced resource consumption when working with just such large fields from the database.
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.
In this episode of the ABAP Freak Show, we take an in depth look at the upcoming 3.0 release of the NetWeaver Business Client. This new version of the NWBC will ship later this year alongside NetWeaver 7.02 and 7.20 based applications. NWBC offers an alternative to using an Internet Browser (such as Firefox or Internet Explorer) for accessing your Portal roles and SAP business applications.
We look at the latest features of the NWBC in this eLearning video. We see how you can setup the NWBC to consume roles from either an ABAP backend system (PFCG) or from a NetWeaver Portal. We look at the new capabilities for SAPGUI for Windows integration, we see advantages to the streamlined navigation and desktop integration capabilities. We also see how external resources (like Twitter, Google, and other search tools) can be integrated into the NWBC.
Finally we look at the SmartClient rendering for Web Dynpro that will ship with NWBC 3.0. With this functionality Web Dynpro applications render with a very lite weight XML output. This XML gets interpreted within the NWBC and rendered as .Net and WPF (Windows Presentation Foundation) on the desktop. This gives you the choice of running Web Dynpro applications in a browser or as a true desktop application – without having to change any coding of the application.

In this weeks’s episode, I’ve just completed the upgrade on my local ABAP Application Server from 7.01 to 7.02. So we use this opportunity to take a quick first look at some of the new features I’ve encountered. This is my no means an exhaustive look at all the new features. We do see the UML Modeler, the source code based class editor, code completion, statement chaining. Also a few new Web Dynpro ABAP features are shown; like Display As Text, Suggest Values, and the Accordion.
