Getting Started with Web-Dynpro ABAP

Getting Started with Web-Dynpro ABAP January 29, 2007

trackback

I played around with the first beta-versions of WebDynpro Java (WDJ) already some years ago, now that NetWeaver 2004s (AS ABAP 7.0) is available I also had the chance to go in for WebDynpro ABAP (WDA). This is the version we will probably work the most with, as it doesn’t need a separate runtime environment, is directly integrated into the ERP-system and thereby makes developing business applications based on ERP-functionality much easier.

I am approaching the topic by working through the book “Web Dynpro for ABAP” by Ulli Hoffmann, which treats the subjects with hands-on examples, various source-code excerpts and screenshots rather than abstract descriptions.

The WebDynpro-framework, development tools and runtime environment apparently bring a lot of advantages to (web-)application developers (and users):

Declarative and graphical tools speed up the development of UIs
The MVC-model leads to a clear separation of layout and business-logic
Data-binding makes it easier to bring the data to the frontend and enables automatic type-checking
The componentization-options allow reuse on the presentation-level of applications
The runtime generates highly interactive, “flicker-free” screens running within a standard-browser

But I have to say that I also like programming BSP’s with HTMLB and the MVC-model very much. This concept has most of the mentioned advantages too, but offers more flexibility I would say, especially when it comes to dynamically generating screens or parts of screens. WebDynpro becomes slightly complex there.

Those are also good starting-points to WebDynpro ABAP (besides the mentioned book):

Hi,

I started getting into the WD4A arena with Ulli Hoffmann’s “bible” and I can only second the above. I think the book has got everything to become a classic in this area.

I posted a little review a while ago here:

Kind regards,

Wow, I have never been contacted by the author of a book I read before
Ulli, I will let you know if I have some notes to your book or questions arise!

not a big deal. I’m glad to get some feedback, and even better if it is positive. I got the chance to write about this topic and since I’m more a programmer than anything else, I tried to put in a lot of examples which can be (more or less) easily recreated. It might be sometimes cumbersome to follow the steps described through multiple pages. I’m currently working on a summary which will be put at the end of each chapter. (in case I get the chance to do a second issue).
Besides that, I could need some feedback on some tool/application ideas in the web dynpro abap area. In case you guys are interested, drop me a mail.

regards, Ulli

Kind regards,
