Hello,
im trying to write the FileInputStream of an uploaded jpeg to a file.
Im using the following code
if(uploadItem.getContentType().equals("image/jpeg"));{
ImageRegistry registry = new ImageRegistry(Display.getCurrent());
registry.put("image", ImageDescriptor.createFromImage(new Image(Display.getCurrent(), uploadItem.getFileInputStream())));
Image image = registry.get("image");
byte[] imageData = image.getImageData().data;
try {
fos = new FileOutputStream(properties.getProperty("imagePath")+uploadItem.getFileName());
fos.write(imageData);
fos.close();
} catch (Exception e1) {
// TODO Auto-generated catch block
e1.printStackTrace();
}
}
But this throws the following Exception
## total: 2395521
filename : IMGP0847.JPG
path : IMGP0847.JPG
content-type : image/jpeg
stream : java.io.FileInputStream@4b12d9

Hi hannes,
it's look like your image input stream can't be read. Check it if it is
already closed or not.
Best,
Ivan

Yep i did close it .
These lines were executed before the other lines of my first post
try {
if (uploadItem.getFileInputStream() != null) {
uploadItem.getFileInputStream().close();
}
} catch (IOException e) {
e.printStackTrace();
}
And i only get the Exception for binary Files, like Images.
i tried also this way, with same results.
Dont work for binary files, all other file are fine.
try {
if (uploadItem.getFileInputStream() != null) {
uploadItem.getFileInputStream().close();
}
} catch (IOException e) {
e.printStackTrace();
}
InputStream fin;
int ch;
StringBuffer strContent = new StringBuffer("");
try {
fin = uploadItem.getFileInputStream();
while ((ch = fin.read()) != -1) strContent.append((char) ch);
fin.close();
}
catch (Exception e)
{
e.printStackTrace();
}
I also tried it with a buffered read , same results.
Works with e.g. text files , dont works with binary files
try {
if (uploadItem.getFileInputStream() != null) {
uploadItem.getFileInputStream().close();
}
} catch (IOException e) {
e.printStackTrace();
}
InputStream is = uploadItem.getFileInputStream();
BufferedReader reader = new BufferedReader(new InputStreamReader(is));
StringBuilder sb = new StringBuilder();
String line = null;
try {
while ((line = reader.readLine()) != null) {
sb.append(line + "\n");
}
is.close();
System.out.println(sb.toString());
}
catch (Exception e)
{
e.printStackTrace();
}
