Do we have any mechanism to persist af:inputFile value

Question

Hi All,
I am using jdev version 11.1.1.4.0.
I have simple page where I took af:inputFile component and one command button.
In that page for form useupload is also set true. Binding of input file is done in bean which has pageflowscope.
Value is binding with UploadedFile Object.
When I press command button then value of input file should be persist it becomes empty.
Do we have any mechanism to persist af:inputFile value.
Thanks
Sainath

I have already used this file upload mechanism, you can directly use these fuctions :
* @param event
* After selection of File from File Browser, this function will get called
public void fileUploaded(ValueChangeEvent event)
UploadedFile file = (UploadedFile)event.getNewValue();
if (!file.getContentType().endsWith("png") && !file.getContentType().endsWith("gif") &&
!file.getContentType().endsWith("jpg"))
FacesContext context = FacesContext.getCurrentInstance();
FacesMessage message = new FacesMessage("Choose a png, jpg or gif file to upload.");
message.setSeverity(FacesMessage.SEVERITY_ERROR);
context.addMessage(event.getComponent().getClientId(context), message);
return;
String strImageDirectoryInDomain = getDashboardThumbnailDirectoryInDomain();
(new File(strImageDirectoryInDomain)).mkdirs();
String strNewImageFileName = getNewImageFileName(file.getFilename());
File oNewFile = new File(strImageDirectoryInDomain + strNewImageFileName);
OutputStream dout = null;
java.io.InputStream oInputStream = null;
try
oInputStream = file.getInputStream();
byte[] bytes = new byte[1024];
int nread = 0;
dout = new FileOutputStream(oNewFile);
while ((nread = oInputStream.read(bytes)) != -1)
dout.write(bytes, 0, nread);
this.strExternalImage = getImagePathRelativeToWEBINF(strNewImageFileName);
if (file != null)
FacesContext context = FacesContext.getCurrentInstance();
FacesMessage message =
new FacesMessage("Successfully uploaded file " + file.getFilename() + " (" + file.getLength() + " bytes)");
context.addMessage(event.getComponent().getClientId(context), message);
return;
} catch (FileNotFoundException e)
e.printStackTrace();
} catch (IOException e)
e.printStackTrace();
public static String getImagePathRelativeToWEBINF(String strImageName)
StringBuilder oBuilder = new StringBuilder();
oBuilder.append("/images/");
oBuilder.append(strImageName);
return oBuilder.toString();
i hope this will solve your issue.
