Are NWDS Mobile Pluggins neccesary to develop Mobile Web Dynpro Online?

Hi all
Do I need to put in NW Developer Studio the pluggins for mobile to develop a Mobile Web Dynpro Online Application (Always Connected scenario)?
Thanks for your answers
Investiga

Hi Investiga,
As Vidya as mentioned you dont have to install anything extra for Mobile Webdynpro Online,
You can use the Webdynpro perspective in NWDS for your development.
Only thing you need to be aware of is the supported elements in the Webdynpro Perspective for Mobile.
The following documentation will help you out.

Hi ,
Mobile WebDynpro
The SAP Web Application Server allows direct online access to Web Dynpro applications using mobile devices. As part of the SAP Web Application Server, Web Dynpro provides a development and runtime environment with which you can quickly and simply create professional user interfaces for desktop PCs or for mobile devices. An appropriate infrastructure and renderer classes are provided for developing mobile Web Dynpro applications for Pocket PCs as well as for BlackBerry Wireless Handhelds and Nokia Series 80 devices.

WebDynpro Java
Web Dynpro is a client-independent programming model of the SAP NetWeaver technology platform for developing user interfaces for professional business applications. It is based on the model view controller paradim which ensures that the business logic is separated from the presentation logic. This architecture is visible in the Web Dynpro perspective of the SAP NetWeaver Developer Studio (NWDS).
Web Dynpro helps you with the development of Web applications by:
·        Ensuring platform-independence with the meta model approach
·        Minimizing the implementation effort through declarative programming
·        Supporting a structured design process by applying the model view controller paradigm
·        Providing reuse and better maintainability by using components
·        Providing graphical support with tools in the Web Dynpro perspective
·        Providing the SAP NetWeaver Java Development Infrastructure (NWDI) which supports team work with different services such as source code versioning and the Central Build Service.

Using External Library in Mobile Web Dynpro Offline

Hi all,
i would like to use a jar in a Mobile Application for Handheld and i followed the steps from the wiki "Using External Library in Mobile Web Dynpro Offline" at
https://www.sdn.sap.com/irj/sdn/wiki?path=/display/home/usingExternalLibraryinMobileWebDynpro+Offline
>How to use External Library in Mobile Web Dynpro Offline
>For using external jar in local deployment scenario, one can do following:
>1. In the dc where jar has to be used, add the jar as external jar classpath entry. It can be done via <dc> > (Right-click)> properties->Java Build Path->Select "add external jar".
>2. Do the programming using the jar.
>3. Shut down the mobile client.
>4. Copy the jar in the "lib" folder of mobile client installation.
>5. Deploy the application in the IDE.
>6. Run the application.
>In 5, the jar will not deployed and will be picked from the lib folder during 6.

>Note: This will work on and after SAP Net Weaver CE 7.1 SR3 with Mobile plugins from CE 7.1 SR3 (and after).
i get a error at the deployment with the message "...package myres does not exist...":

Hi,
1) in Development Infrastructure Perspective -> rightklick in Navigator/Projekt Explorer -> new Project -> (Development Infrastructure) Development Component (DC).
NWDS generates Project Ressources e.g. the folder "libraries"
2) copy the jars to the "libraries" folder.
3) rightklick on the newly created Development Component (DC) -> Development Component -> Show In -> Development Properties -> go to the Tab "Public Parts",
in -> "Defined Public Parts" -> klick on Button "Add" -> give a name for "Public Part" -> at "Purpose" select "Compilation" -> Finish.
rightklick on the newly created Public Parts -> select "Manage Entities" and select the jars you want to use -> Next -> Finish.
4) switch to the Mobile Apps for Handhelds Perspective -> in Development Component select e.g. the Service Component or the UI Component ->
rightklick -> Development Component -> Show In -> Development Properties -> got to Tab "Dependencies" -> klick on Button "Add" -> under the Node MyComponents -> select the newly created Development Component with the Public Parts/jars (that was created in 1 - 3).
thats all, now you can deploy your application

FunctionKey & BarCodeReader API in Mobile Web Dynpro

Folks,
I am developing a few applications using Mobile Web Dynpro (Java), for PSION TEKNOLOGIK 7535. (Windows CE 5.0 with IE 6.0 for CE)
I have to use the API's of the Mobile Add-On Library, namely the FunctionKey API and the BarCodeReader API.
So the SAP Note says that these are supported only for Symbol and Intermec device.
I would like to know what options I have for this implementation
Can i use a Mobile WebDynpro Client? ( will these API's work if I use the WebDynpro client instead of IE?)
Can I use any other browsers instead of IE and use the above mentioned API's?
Are there any third party software's that support these functionality?
Thanks,
Balaji

Hi Balaji,
Unfortunately the only option you have is to use either a symbol or an Intermec device. Symbol and Itermec both have a special browser with which you can funtion keys or Barcode Reader.
I think "Mobile WebDynpro Client" you talk about is the offline client but the FunctionKey and the BarcodeReader will work with the online version only.
I dont know of any workaround for this.
Best Regards,
Karthik

Mobile Web Dynpro offline

I was wondering if any one has any information the Mobile Web Dynpro Offline Development Object when creating a DC. Their is a perspective for it as well... I tried creating a webdynpro (look like a normal webdynpro) but it will not run... I also noticed their is an option on a standard Webdynpro to convert it to a Mobile Web Dynpro Offline as well...
Oh yea this is in the 04s SP6 NWDS.
D.

Hi Derek,
The Mobile Webdynpro offline was only available until SP8 for internal purposes and is not meant for external customers. It wont run because you need to run the application on a SAP Mobile Client and not on the J2EE !

Creating mobile web dynpro application which customized theme

Hi guys,
I have created a mobile web dynpro application and a theme with Theme Editor. Then I have appended this theme with the sap-cssurl parameter to my application.
my_application? sap-cssurl=http://host:port/webdynpro/resources/sap.com/tcwddispwda/global/SSR/themes/MyTheme
It works well in my first testing on my laptop.
In order to test it on my mobile device I have also appended sap-wd-client parameter to my application. Now my URL looks like
my_application? sap-cssurl=http://host:port/webdynpro/resources/sap.com/tcwddispwda/global/SSR/themes/MyTheme&sap-wd-client=PieClient
It doesnt work. My application layout looks as if I dont use the theme. Did somebody have the same problem and can help me by finding a solution.
Thanks for your answers.
Marita

Hi Marita,
Mobile Web Dynpro supports several handheld mobile devices. I guess yours is a Pocket PC. Except the newest Pocket PC 2003, all the other versions don't have CSS support. Therefore the current Pocket PC client "PieClient" of Web Dynpro lacks the ability for customized themes. On the other hand, themes are supported for more advanced devices, such as Nokia Communicator 9500/9300.

Wei

Emulators for testing mobile web dynpro

I am developing mobile web dynpro applications and need emulators to run them. Can anyone suggest the URLs to download the emulators (Pocket PC, BlackBerry, and Nokia series 80). As I do not have the real device to test the applications, I need the emulators badly to test the applications.

Hi Kishore,
sorry i am not using BlackBerry,only Windows mobile.
There i only have to enter the URL of the WD-Application into the Device Browser of the simulator.
I noticed from this threads that Vikram has the same problem as you.

HCM Development in Web Dynpro (ABAP)

Hi,
I am working in SRM custom development in Web Dynpro (ABAP). I have to work now with HCM development.
Is it any specific method or procedure to develop/change the Web Dynpro (ABAP) application .I am new to HCM Functional.
Pl help me.
Thanks in advance.
sri

Hi,
In the HCM(Humaan Capital management) also there are the related FM ie BAPIs and also the corresponding BOR (business objects) where you can use them in the WDA.
Here the data is stored in Infotypes. Where all the historical records for each employee/organization etc are maintained.
It's better to have an idea on the HCM structure that would be enough in understanding the BAPIs etc.

Can you please help me with this...

Hi Gary,
> Now do I put this back in original directory
Rrrighty.
> do I need to add back .bak or leave as .par?
Leave as PAR. If the server starts, all .par files within this directory get deployed and in the case of success, .bak gets added. So .par.bak files are not deployed again on the next startup.
> do I need to delete original
> then add my updated version?
I think you don't need to delete the original, but just do it. If your changed .par file get deployed successfully, it will overwrite the old .par.bak anyhow.
But make a security copy of the orginal file for the case that you have changed the original PAR in some strange way
Hope it helps

How to run mobile web dynpro application

Hi experts,
I'm using NetWeaver Developer Studio for Mobile SP03.
I create a mobile application for handhelds including 2 components:
- Mobile Application.
- Mobile UI Component (web dynpro component).
I do follow the tutorial for creating the application. I can deploy and run the application on NWDS handheld emulator successfully.
When I deploy it on my SAP Application server to test the web dynpro UI application via a web browser, it throws out a java.lang.ClassNotFoundException: the class <package name>/Internal<Application Name>Comp.class cannot be found by WD framework when I access it. It can be deployed without error and is alive in the web dynpro content admin.
I found that the normal WD component the class Internal<Application Name>Comp is generated during the building process but it is not when developing mobile UI component.
Can anyone tell me there is any difference between the two WD component types? Does my server need to install any extra component for running mobile UI component? Or do I need to configure my NWDS for Mobile to make the application work on SAP server?
Thank you very much,
Steven Linh Nguyen.

Hi,
Mobile webdynpro application for handheld cannot be deployed on SAP AS.
To use the Mobile webdynpro application for handhelds follow the steps:
1. Upload sda files of all DCs to the DOE server (Transaction SDOE_UPLOAD_ARCHIVE) which will be availabe at the location
<workspace.jdi>\LocalDevelopment\DCs\demo.sap.com\<DC>\_comp\gen\default\deploy
2. Install the simulator on laptop or client on PDA
3. Deploy uploaded MCDS(from step1) to the client, after the device registration.
Thanks and Regards,

Why Web services are used to send data not HTTP in Web dynpro for Java?

Is Web Dynpro for Java supports Web service , RFC as communication to other systems why http cannot be used in Wweb dynpro for java.........
Thanks and Regards,
CSP

Hi Pradeep,
Yes, Web Dynpro java supports web service, you can expose your web service as RFC Model to
communicate with others system. As per as HTTP is concern we don't have any
supportive method in web Dynpro. Insted of HTTP we use context in web dynpro to communicate.
Thanks

I want to know what sort of the objects developed using web dynpro

Hi all ,
Pls specify few things on what is done using webdynpro and its uses.
Thanks .

Web Dynpro is SAP's primary UI strategy for its applicaitons moving forward. The Business Suite will delivery its new screens primarily in Web Dynpro ABAP. The NetWeaver Middleware, Business By Design, and Composite Applications primarily use Web Dynpro Java. Web Dynpro is focused on UIs that represent complex business applications, but is not limtied to browser based clients. It is client indepent rendering and is always stateful.

Are NWDS Mobile Pluggins neccesary to develop Mobile Web Dynpro Online?
