Hi,

use this for file download.

For file down load u have to use a UI element as "File download".

u just create context attribute as setdownload_res and file data.

setdownload_res as of type "com.sap.ide.webdynpro.uielementdefinitions.Resource" then bound it to the ui element "resource".

file data as of type "com.sap.tc.webdynpro.progmodel.api.IWDInputStream"

and set calcuclated as true and read only as true.

then in doinit method u just write this code

IWDAttributePointer attr = wdContext.currentContextElement().getAttributePointer("fileData");

IWDResource res = WDResourceFactory.createResource(attr,null,WDWebResourceType.UNKNOWN);

wdContext.currentContextElement().setDownload_res(res);

wdComponentAPI.getMessageManager().reportSuccess(""+c);

after this in the getter method u write this code

IWDInputStream stream = null;

try

{

stream = WDResourceFactory.createInputStream(new FileInputStream(new File("<pathof the file to be download>")));

}

catch(Exception e)

{

e.printStackTrace();

}

return stream;

Hi Satish

Thanks for your response.

Hope it is helping me.

Can u please clarify one thing,inside the getter method while creating an instance of IWDInputStream the path to the File to be downloaded means ,the path of the File in the Application Server or Presentation Server?

If it is Application Server ,then How can i get the path where it is storing the File?
