File not found exception

Dear All,

I am trying to open a file which is located at

src/mimes/Components/com.sap.tut.wd.uploaddownloadinteractiveform.UploadDownloadInteractiveFormComp,

I am using this sample code given by sap..

*

IWDAttributeInfo attInfo =

wdContext.currentContextElement().node().getNodeInfo().

getAttribute("PdfSource");

ISimpleTypeModifiable type = attInfo.getModifiableSimpleType();

IWDModifiableBinaryType binaryType = (IWDModifiableBinaryType) type;

binaryType.setFileName("TravelRequest.pdf"); // Set file name

binaryType.setMimeType(WDWebResourceType.PDF); // set the mime type

String fileName ="temp
webdynpro
web
local
TutWD_UploadDownloadInteractiveForm_Init
Components
com.sap.tut.wd.uploaddownloadinteractiveform.UploadDownloadInteractiveFormComp1
TravelRequest.pdf";

// path to the source file

/* converts the binary file to a byte array and moves it to the text element */

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);

}

*

But I am getting runtime exception...

java.io.FileNotFoundException: temp\webdynpro\web\local\TutWD_UploadDownloadInteractiveForm_Init\Components\com.sap.tut.wd.uploaddownloadinteractiveform.UploadDownloadInteractiveFormComp1\TravelRequest.pdf (The system cannot find the path specified)

Please tell me what could be the reason...

Thanks in Advance
