WebDynpro and ABAP


I have been entrusted with researching WebDynpro Development and the languages that it supports for our Development roadmap team. Going through the many articles in SDN this is what I understand:

With the MVC ( Model, View, Controller ) paradigm of UI development for WebDynpro, View and Controller development and enhancement can only be done using Java. Is my understanding correct? In other words the traditional PAI/PBO's of Screen flow logic will now have to be done using Java? Does SAP have any plans of supporting the traditional flow logic within the SAP Netweaver Development studio? or is it imperative for developers to learn Java?

Based upon the information I gather, I will be making a recomendation to my Devlopment and Languages Steering committee.

Any and all input is highly appreciated!

    Hi John,

    I can respond to part of your question. Currently Web Dynpro for Java is the only version available externally to customers. Web Dynpro for ABAP will be available with NW05. Web Dynpro for ABAP will still utilize the MVC paradigm and the "connector code" will be in ABAP.

    The latest version of Web Dynpro for ABAP that I was exposed to showed essentially the same end-user functionality that is available in Web Dynrpo for Java. Of course, the Java version offers some extra development options including developing on the local developer's desktop. (Rather than on a centeral server with ABAP.)

    Starting in NW05 the choice will really be up to the customer for what works best for them. Judging from your e-mail, you sound like a primarily ABAP (as opposed to Java) shop. If that's true, Web Dynpro for ABAP may well

    be the choice for you.

    Hope this helps a bit,

    • Hi John,

      I'll have to let someone else field this if they know more than I do. Since WebDynpro for ABAP is not scheduled to be available to customers until NW05, I don't think there is a preview version yet available.

      I guess I would expect it to come out some time after the general release of NW04 (likely in October).

      Sorry I couldn't be of more help,
