hi,

Once store your text file in location of the your local drive and goto the NWDS and close the application and open the application once again.

And verify the file is available over there or not I means to say mimes-components-<package name>-text file.

See this first

Hi Shami:

I think you have to go and place ur a.txt file here:

in webdynpro click on navigator > select ur proj 'sample' > src > mimes > Components > com.sss.sample.Sample > paste ur a.txt here in this directory.

and deploy it now.

u shudn't get any error now.

Just try with

File f = new File("a.txt"); instead of giving full path.

Hi Shami,

First check the file part of the .ear or not ?

- Build the project. and go to the project folder in windows explorer and open the <project>.ear file.

Open the ear and open .wda file inside it.

Go to the components folder and check document .The doc should present in that component.

Now in the code no need to enter complete path.Just give the file name.

Hi Shami,

try this one instead of locating the file path manually:

String resourcePath = WDURLGenerator.getResourcePath(wdComponentAPI.getDeployableObjectPart(), fileName);

Hi,

This link explains all your requirement.

https://www.sdn.sap.com/irj/sdn/downloaditem?rid=/library/uuid/2dd3dbcd-0401-0010-55b8-b10808ff688e

Go thru this

or other wise use this code

IWDAttributeInfo attInfo = wdContext.currentContextElement().node().getNodeInfo().getAttribute("PdfSource");

ISimpleTypeModifiable type = attInfo.getModifiableSimpleType();

IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) type;

binaryType.setFileName("TravelRequest.pdf");

binaryType.setMimeType(WDWebResourceType.PDF);

String fileName = "temp
webdynpro
web
local
TutWD_UploadDownloadInteractiveForm
Components
com.sap.tut.wd.uploaddownloadinteractiveform.UploadDownloadInteractiveFormComp
TravelRequest.pdf";

try

{

File file = new File(fileName);

FileInputStream in = new FileInputStream(file);

ByteArrayOutputStream out = new ByteArrayOutputStream();

int length;

byte[] part = new byte [10 * 1024];

while ((length = in.read(part)) != -1)

{

out.write(part, 0, length);

}

in.close();

wdContext.currentContextElement().setPdfSource(out.toByteArray());

}

catch(Exception e)

{

throw new WDRuntimeException(e);

}

thanks,

Lohi.
