Mobile WebDynpro BarCodeReader Problem (Intermec)

[Former Member]

Hi,

I'm trying to use the BarCodeReader API (Mobile WebDynPro Add-on library) for Intermec BarCode Scanner, following <a href="http://help.sap.com/saphelp_nw04s/helpdata/en/b7/3efd406b8af16fe10000000a1550b0/frameset.htm">this</a>.

My wdoModifyView looks like:

if (firstTime) {
 
		IWDBarCodeReader barCodeReader = (IWDBarCodeReader) view.getElement("BarCodeReader");
 		barCodeReader.mappingOfOnRead().addSourceMapping( IWDBarCodeReader.IWDOnRead.BAR_CODE, "scanData");
		barCodeReader.mappingOfOnRead().addSourceMapping(  IWDBarCodeReader.IWDOnRead.TYPE, "type");
		
	}

Unfortunately, after i launched the IExplorer and visit the webdynpro page, it have no effect. My UIElement: BarCodeReader has the following properties:

enabled=true

type=intermec

visible=none

Depending on the manufacturer of the Pocket PC, you need to use one of the following browsers in order to use the functions in mobile add-on UI elements:

■      INTERMEC devices: IBrowse

!! Can't I use the IExplorer browser? My Mobile device doesn't provide that "IBrowse"

Any help would be appreciated. Thanks in advance.

You can still continue using the IExploer browser but to fully leverage the Barcode reader functionality (onRead) you will require IBrowse.

Thanks Chintan, I'm using IBrowse now, but a new problem has come.

When I press the button, an Exception says "Parameter barCode not found".

I'm also using the parameter sap-wd-client=PieClient

I mapped it!

Thanks in advance,

Antoni,

sap-wd-client is used when you want to force rendering on mobile devices. Did you try without adding this?

Hi again,

Yes I tried it before posting, but it gives me an exception WDRuntimeException at handleUIElementEvent(PieClient.java:895) when I press the button.

Another idea?

Thanks Chintan for your dedication

Antoni,

Could you give more details like what version of NetWeaver you are on and which device are you using and what is its OS ?

Hi Antonie,

Just to share with you my experience with Ibrowse.

From what i noticed, each time u press the scan button of the Intermec scanner, it will invoke the WDP application and passed along the scanned value via onActionScan method. Here you can do your own logic.

In contrast, for mobile IE, you need to point the cursor to the WDP application's input field and press to scan. Then, the scanned value will be entered into the cursor pointed field, but it doesnt really invoke the WDP application.

//assumed you have a context attribute called data which is binding to an input field

public static void wdDoModifyView(IPrivateMLTMAppView wdThis, IPrivateMLTMAppView.IContextNode wdContext, com.sap.tc.webdynpro.progmodel.api.IWDView view, boolean firstTime)
  {
    //@@begin wdDoModifyView
	if (firstTime) {
				  IWDBarCodeReader barCodeReader = (IWDBarCodeReader)view.getElement("BarCodeReader");
		  barCodeReader.mappingOfOnRead().addSourceMapping("data","scanData");
		  
	}
}

//scanData is the scanned value
  public void onActionScan(com.sap.tc.webdynpro.progmodel.api.IWDCustomEvent wdEvent, java.lang.String scanData )
  {
    //@@begin onActionScan(ServerEvent)
    
    if(wdThis.wdGetContext().currentContextElement().getData() ==null){
		
		wdThis.wdGetContext().currentContextElement().setData(scanData);
    }	
    //@@end
  }

Hi ,

Our current project requirement is to manipulate the scanned data from a barcode scanner. The handheld device used is Symbol and the browser is PocketBrowser. The problem we are facing now is that the onRead event of BarcodeReader UI element is not been invoked on scanning a barcode. There are 2 inputfields in the application. If the cursor is placed on first input field , the scanned value is placed on the first field and like wise for second inputfield.

Either we should be able to trigger the scan event of the UI element or we should be able to find the current position of cursor.

Please help with valuable inputs.

Thanks n Regards
