Restrictions on the Web Dynpro Java for Mobile

Hello everybody,

We are starting to develop Web Dynpro Java applications for Windows based hand held devices.

Before starting, i wanted to check on few things:

1. Is Date Picker element now works in the WDJ for Mobile? I know in past, there were some issues with that. IS that issue still persists? I am planning to use the normal date feature which is tied to the input field by assigning Date type context field.

2. Can we use the custom theme for WDJ for Mobile? Or is there any restrictions?

3. Is there any problem with using Dropdown values for WDJ for Mobile?

4. Is search help works fine in WDJ for Mobile?

Let me know if someone has developed WDJ for Mobile recently and come across above scenarios.

Also, please let me know if there are any other specific restrictions in using WDJ for mobile?

Thanks,

Bhavik

    Hi Bhagat,

    Using WDJ (Pie03Client/PieClient) will work with most RF devices - and if it doesn't, you can always install a DataWedge for that. Browser aspects, you will have to consider which license your client have in their devices - I would say usually is Pocket IE (my client works with Motorola MC31XX's so I can use SPB/RhoElements).

    Another thing to consider here is how this whole AS Java technologies work in SAP environment: there is no such thing as 'documentation', 'release notes' or 'demo/poc' - The best approach is to do what Tobias suggested: Build yourself a Proof of Concept and show your client the capabilities of the platform - I find rather unlikely you will ever find proper documentation in SAP. (I was never able to find..)

    But for instance, I can tell you simple things that doesn't work, so this will give you an idea of the Pie03Client:

    - width/height doesn't work for most UI Elements, no matter what you do the UR/Pie03 does not render it;

    - many UI Elements have no render defined in Pie03Client - for instance, hr or iFrame.

    And I still have to use WDJ Mobile (Pie03Client) - one of the biggest (if not the biggest) food retailers in the country I live uses it and doesn't want to move forward. Somehow it works for them (and when it doesn't I just open up the JAR's and I do stuff myself)

    Back to the main topic:

    1. Is Date Picker element now works in the WDJ for Mobile? I know in past, there were some issues with that. IS that issue still persists? I am planning to use the normal date feature which is tied to the input field by assigning Date type context field.

    - No Date Picker.

    2. Can we use the custom theme for WDJ for Mobile? Or is there any restrictions?

    - No Theme. (Pie03Client) - basically, this client has no CSS. I also believe that theme is part only of the HTML client.

    3. Is there any problem with using Dropdown values for WDJ for Mobile?

    - Yes. DDBI/DDBK will not respect ContextNodeCardinality/SimpleValueSet - on Pie03Client there is always a 'blank' row being displayed, which causes a 500 in the framework when selected. NW73, latest SP. PieClient I believe contains the same issue, thou no 500 on roundtrip.

    4. Is search help works fine in WDJ for Mobile?

    - Not that I'm aware off.

    @Tobias: No matter how much QQ around that topic, IMO all it took was Oracle acquire Sun and boom..

      Hi Daniel,

      Thanks for you answer. I finally found a "solution" by using RadioButtonGroup instead of DropDown. As I don't have much information to show, it was a possible solution to that problem.

      I now WDJ is not the good way of working anymore but I wanted to avoid developping again an old working application.

      Thanks again for your help.


      Best regards,

      Thomas

    • I understood that you want a list of features that work and not work for WDJ mobile: that isn't going to happen. That kind of evaluation is part of every analysis of a possible solution and heavily depends on your project requirements. The expert here in the forum cannot do that kind of work for you, sorry.

      Just develop a WDJ application and access it via a mobile browser and see what happens. Very soon you will discover that WDJ mobile is not a good choice for mobile applications.

    Sanjay,

    I would recommend you create a component of type Potal JSP, and connect to the backend through a system (NW 7.0) or destination (NW 7.3). Soon after, create a custom login screen for mobile devices in Portal.

    Here is a code snippet showing the connection to a destination:

    IPortalRuntimeResources iPrtRsrc = PortalRuntime.getRuntimeResources();

    IDestinationsService destinationsService = (IDestinationsService) iPrtRsrc.getService(IDestinationsService.KEY);

    IDestinationWrapper destinationWrapper = destinationsService.getDestinationWrapper(userContext, destinationName);

    hintAreCredentialsSet = destinationWrapper.hintAreCredentialsSet(userContext);

    if (hintAreCredentialsSet) {

    connection = destinationsService.getConnection(userContext, destinationName);

    }

    If you need more info... search about JPA or send-me a mail.

    att,

    Angelo
