Use the LinkToUrl UI Element.

intCounter parameter is not required.

Call the DownloadFile anywhere in the view controller preferably in the onPlugXXX method.

You need to have two root level context attributes ctx_URL and ctx_URLText of type string .

Bind the ctx_URL attribute to the REFERENCE property of the LinkToUrl UI Element and the ctx_URLText attribute to the TEXT property of LinkToUrl UI Element.

This should work..

Hi Noel,

The code pasted by Kanwalpreet will not work..I know it because I have written this code...KANWALPREET , next time please make sure that the code is working before copying and pasting it here so that you don't mislead others.

The working code is as follows:

codepublic void DownloadFile( int intCounter )

{

//@@begin DownloadFile()

//Getting the message manager

IWDMessageManager msgMgr = wdThis.wdGetAPI().getComponent().getMessageManager();

String strAppraisalID = "";

String strLocation = "";

String strPath = "/documents";

String strUrl = "";

String strUserID = "";

String strFileName = "";

String strLevel = "";

RID objNewRid2 = null;

ResourceContext objResourceContext = null;

IUser ep5User = null;

IUriReference objUriReference = null;

com.sap.security.api.IUser objSAPUser = null;

try

{

strLevel = wdContext.currentContextElement().getCtx_Level();

// //Getting the appraisal id of the employee

strAppraisalID = wdContext.currentContextElement().getCtx_AppraisalID();

//Getting the current user

objUser = WDClientUser.getCurrentUser();

//Getting the SAP user

objSAPUser = objUser.getSAPUser();

//Getting the EP user

ep5User = WPUMFactory.getUserFactory().getEP5User(objSAPUser);

//Getting the resourse context of the EP user

objResourceContext = new ResourceContext(ep5User);

//Getting an instance of the resource factory

objFactory = ResourceFactory.getInstance();

//Getting the final location or destination

strLocation = strPath"/""AUT";

//Getting the resource ID of the final location

objNewRid2 = RID.getRID(strLocation);

//Getting the collection of resource of final location

objResourceCheckFolderAppraisal = (ICollection)objFactory.getResource(objNewRid2,objResourceContext);

//Checking if the resource is not null

if (objResourceCheckFolderAppraisal!=null)

{

//Getting children of that resource into a resource list

objResourceList = objResourceCheckFolderAppraisal.getChildren();

}//if (objResourceCheckFolderAppraisal!=null)

//Checking if the resourcelist is not null

if (objResourceList!=null)

{

//Obtaining an iterator object on this resource list

objResourceListIterator = objResourceList.listIterator();

//Looping till the resource list has elements

while (objResourceListIterator.hasNext())

{

//Getting next element into a temporary object

objTempResource = objResourceListIterator.next();

strFileName = objTempResource.getName();

//Generating the URL service

objService = (IURLGeneratorService)ResourceFactory.getInstance().getServiceFactory().getService(IServiceTypesConst.URLGENERATOR_SERVICE);

//Getting the relative URIReference from the service object

objUriReference = objService.getRelativeUriPathKey.CONTENT_ACCESS_PATH).appendPath(objTempResource.getRID().toExternalForm());

//Getting the URL by converting the URIReference to string

strUrl = objUriReference.toString();

//Setting this URL to context attribute that is bound to the REFERENCE property of LInkToURL UI Element

wdContext.currentContextElement.setCtx_URL(strUrl);

//Setting this string to context attribute that is bound to the TEXT property of LInkToURL UI Element

wdContext.currentContextElement.setCtx_URLText(strFileName);

)

}//end of while (objResourceListIterator.hasNext())

}//end of if (objResourceList!=null)

}//end of try

catch(Exception e)

{

//Getting the message

String msg = e.getLocalizedMessage();

//Checking for null values and zero length of message

if ((msg==null) || (msg.length()==0))

{

msg = e.getMessage();

}//end of if ((msg==null) || (msg.length()==0))

if ((msg == null) || (msg.length() == 0))

{

//Converting the message into string

msg = e.toString();

}//end of if ((msg==null) || (msg.length()==0))

//Reporting the exception

msgMgr.reportException(msg,true);

}//end of catch

finally

{

strAppraisalID = null;

objNewRid2 = null;

strUrl = null;

}//end of finally

//@@end

}[/code]

You need to create a folder named AUT in the documents folder of your KM i.e go to Content Management->KM Content and create a folder there. Upload a file into this folder and your code should work fine .Just don't forget a WebDynpro Sharing Reference to sap.com/com.sap.km.cm
