Using FileUpload Extension: Uploaded images are corrupt/distorted/lesser size
Hi,
I am not able to properly upload an image file (binary) to the Restlet
server using the Filepload extension. The uploaded images are either
corrupt/distorted looking or they are of lesser size than original.
I have tried using both FileItem.write(File f) method & using the
InputStream.
Are there any special properties/methods to be set for uploading a binary
data ?
I have been using curl to upload the image with the following command
curl -F "upload=@img.jpg;type=image/jpg;filename=img.jpg"
http://localhost:
One strange behavior is that, when in the curl command, the type parameter
is changed to image/jpeg, the uploaded image is still corrupt & distorted
but looks differently in the picture manager than the one uploaded with
image/jpg.
Please help.
PS: The versions of different libs used:
restlet-2.1-SNAPSHOT
commons-fileupload-1.2.1/1.2.2 (both tested)
commons-io-1.3.1
servlet-api-2.4
portlet-api-1.0
Following is the code snippet.
DiskFileItemFactory factory = new DiskFileItemFactory();
factory.setSizeThreshold(1000240);
RestletFileUpload upload = new RestletFileUpload(factory);
List items = upload.parseRequest(getRequest())
.
.
for (final Iterator it = items.iterator(); it.hasNext();) {
DiskFileItem fi = (DiskFileItem) it.next();
// Process the items that *really* contains an uploaded
// file and save them on disk
if (fi.getName() != null) {
InputStream is = fi.getInputStream();
final int size=1024;
byte[] buf;
int ByteRead,ByteWritten=0;
BufferedOutputStream outStream = new BufferedOutputStream(new
FileOutputStream(uploadedFile), size);
buf = new byte[size];
while ((ByteRead = is.read(buf, 0, size)) != -1) {
outStream.write(buf, 0, ByteRead);
ByteWritten += ByteRead;
}
outStream.flush();
outStream.close();
is.close();
//fi.write(uploadedFile)
}

Lokendra

Re: Using FileUpload Extension: Uploaded images are corrupt/distorted/lesser size
Hi,
The problem occurs with text Files (with the pieces of text misplaced) as
well and not just binary data.
The users of this extension, please throw some light !

RE: Using FileUpload Extension: Uploaded images are corrupt/distorted/lesser size
Hi Lokendra,
The internal connector on the 2.1 snapshot isn’t fully stable yet. I suggest
pluging Jetty or Simple extensions for now. That should help here.
Best regards,
Jerome

Re: Using FileUpload Extension: Uploaded images are corrupt/distorted/lesser size
Upgrading to the latest restlet snapshot solved the case.
Thanks
