Download picture of table

Hello, I have a table where one of the columns has an input file, a download button and a picture. The idea would be when I upload the image you selected that it appears in the component of the image.

The problem that when I click on download, does not make the image loading. Aprece the mistake of saying I have to make a choice, even if you did.

Down to show my table code and methods, I use the component file, the button and load the image. My version of jdev is 11.2.4.0

The methods are:

private UploadedFile imageFile.

{} public void setImageFile (imageFile UploadedFile)

this.imageFile = imageFile;

}

public getImageFile() {} UploadedFile

return imageFile.

}

{} public void uploadImageFileAction (ActionEvent actionEvent)

System.out.println ("upload!");

File directory = new File("C://ADF//");

get all files in a directory

File FListe [] = directory.listFiles ();

for (file: FListe) {}

Remove all previously downloaded files

If (!) "{NoImage.png".equalsIgnoreCase (file.getName ()))}

leader. Delete();

}

}

Download the currently selected file

Channel indicator = uploadImage (imageFile);

If (NO".equalsIgnoreCase (flag)) {" "}

FacesMessage msg =

new FacesMessage ("this is not an Image file, please download supported file type (.jpg, .png, etc.)" ");

msg.setSeverity (FacesMessage.SEVERITY_ERROR);

FacesContext.getCurrentInstance () .addMessage (null, msg);

}

}

To store the path to the downloaded Image file

String imagePath = null;

{} public void setImagePath (String CheminImage)

this.imagePath = imagePath;

}

public String getImagePath() {}

return imagePath;

}

private String uploadImage (file UploadedFile) {}

File UploadedFile = myfile;

If (myfile == null) {}

} else {}

System.out.println ("TYPE:" + myfile.getContentType ());

If (myfile.getContentType().equalsIgnoreCase("image/jpeg") |

myfile.getContentType().equalsIgnoreCase("image/png") |

myfile.getContentType().equalsIgnoreCase("image/bmp") |

{myfile.getContentType().equalsIgnoreCase("image/gif"))}

Path of the folder on the drive

Path String = "C: / / ADF / /";

Type string = "PNG";

String TypeVal = ".png";

If (myfile.getContentType().equalsIgnoreCase("image/jpeg")) {}

Type = "JPEG";

TypeVal = ".jpeg";

(} ElseIf (myfile.getContentType().equalsIgnoreCase("image/png")) {}

Type = "PNG";

TypeVal = '.png ';

(} ElseIf (myfile.getContentType().equalsIgnoreCase("image/bmp")) {}

Type = "PNG";

TypeVal = '.png ';

(} ElseIf (myfile.getContentType().equalsIgnoreCase("image/gif")) {}

Type = "GIF";

TypeVal = ".gif";

}

InputStream inputStream = null;

try {}

Generate a unique name for an image uploaded with date time

DateFormat dateFormat = new SimpleDateFormat ("yyMMdd_HHmmss");

Date date = new Date();

String dtTime = dateFormat.format (date);

dtTime = dtTime.replace ("", "_");

String name = 'IMG', '_' + dtTime;

System.out.println ("file name is" + name);

inputStream = myfile.getInputStream ();

Enter BufferedImage = ImageIO.read (inputStream);

Writing the file to the path

File outputFile = new file (path + name + TypeVal);

ImageIO.write (input, type, outputFile);

imagePath = outputFile.getAbsolutePath ();

System.out.println ("path:" + imagePath);

} catch (Exception ex) {}

handle the exception

ex.printStackTrace ();

} {Finally

try {}

inputStream.close ();

} catch (IOException e) {}

}

}

} else {}

imagePath = "NO";

}

}

setImageFile (null);

return imagePath;

}

Thank you for your help. It is very important to solve the problem
