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

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.

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

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.

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 !

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.

Difference between mobile web dynpro and simple web dynpro application

Hi Everyone,
Can anyone pls let me know what's the difference b/w mobile web dynpro application and an offline or simple web dynpro application.
Thank U!!
Ravi Aswani

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.
http://help.sap.com/erp2005_ehp_03/helpdata/EN/fa/100d4113eff16fe10000000a1550b0/frameset.htm
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.

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,

Specific SC Dependency for using KM API in Web Dynpro DC

Hi,
I want to use KM API in my Web Dynpro DC.
Currently, I have created it as Local DC and I am using External Lib DC to make use of JARs required for KM APIs.
So my question->
While doing it in NWDI track, is there any special KM specific SC dependency I should include in my track?
Or just standard dependecies (SAP-JEE, SAP_BUILDT, SAP_JTECHS) would be sufficient?
Thanks and regards,
Amey Mogare

Hi Amey,
Since you have created an external library DC for the jars, Just add all this jars to public part and use this public part in the required DC.
You have to add the following sharing referece to ur project (which is used at runtime).
Go to webdynpro refernces>sharing references in properties of webdynpro project
Add PORTAL:sap.com/com.sap.km.application
No need to add any SC dependency, the standard dependecies would be sufficient
For more information pls go through this blog

Hope this helps you..

also go through the following
Using the FunctionKey
Use
The FunctionKey allows you to trigger a Web Dynpro action using a specific key on the mobile device. In the following example, this UI element is used to navigate to another view via a specific key.
Prerequisites
●     The SAP NetWeaver Developer Studio is installed on your computer, and you can use it to create your mobile Web Dynpro application
●     You have access to a SAP NetWeaver Application Server, where you are running the Web Dynpro application
●     You are using a Pocket PC with special scanning equipment manufactured by Intermec Technologies or Symbol Technologies
●     You have created two views in a Web Dynpro project and called them StartingView and TargetView.
Procedure
       1.      Navigate to the StartingView and double-click the view or choose Edit from the context menu.
       2.      Insert the mobile UI element FunctionKey.
       3.      Switch to the Plugs tab, create an outbound plug with the name fromFunctionKey and define the navigation link to the TargetView.
       4.      Switch to the Actions tab page and define an action called NavigateToAnotherView.
       5.      Assign the value IBrowse_OnKey49 to the keyCode property of the FunctionKey.
       6.      Assign the NavigateToAnotherView action to the onAction event of UI element NavigateToAnotherView.
       7.      Switch to the Implementation tab and add the following source code to the implementation of the view controller. The read data is passed to the context and the relevant context attribute is set.
public void onActionNavigateToAnotherView(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent )
   //@@begin onActionNavigateToAnotherView(ServerEvent)
   wdThis.wdFirePlugFromFunctionKey();
   //@@end
Result
By pressing press key 1 on the mobile device, you navigate to the TargetView.

Queries on Web Dynpro

Hi All
I have few queries
1. Is it possible to launch an external web application in new browser using suspend plug? If yes can you please share the details how can we do it?
2. Is there any API available in Web DynPro which I can use to launch an external application in new browser window on click on a button?
3. Does HttpUrlConnection work inside Web DynPro runtime? I tried to use it in a web dynpro application to check http responsecode but in all run I got exception like connection timed out or invlid url.
Thanks in advance
Sudip

Hi Shikhil
Thanks for your reply.
But sorry, I couldn't make sense out of it. The requirement is specifically having a button on the screen on click on which a new browser will be launched with an external web application.
You mentioned to have a LinkToUrl and a LinkToAction but the flow you said not clear to me. LinkToUrl doesn't have an action attached to it and user needs to click on the link explicitly for launching the url . So if I even open a new window on action of LinkToAction how can it automatically launch the url in new browser using LinkToUrl?
Thanks
Sudip

Using Ajax in Web Dynpro

Hello everyone,
I need to use an Ajax Script (namely the Google Maps API) in a Web Dynpro project. Is this possible? And if: How to realize? I would be happy about any suggestions.
Greetings Marco

Hi,
It is possible.
The Google Maps JavaScript API lets you embed Google Maps in your own web pages. To use the API, you need to sign up for an API key and then follow the instructions specified in the link http://www.google.com/apis/maps/documentation/.
You need use the javascript API and there is no specific webdynpro API available.
Refer to the links below:
1. Is Web Dynpro using AJAX?
2. Change the way you write AJAX based Web applications.
3.This is a very good blog:
Google Map Services for your Site/Portal
4. Visual Composer demo - Customer and Google API
