Martin,
Would you be kind enough to give an example?
I tried the following:
ajaxSimpleUploadForm.add(new AjaxButton("uploadVideoSubmit") {
@Override
protected void onSubmit(AjaxRequestTarget target, Form<?> form)
{
AbstractResourceStreamWriter writer = new
AbstractResourceStreamWriter() {
@Override
public void write(Response output) {
for(FileUpload upload : uploads) {
System.out.println(new Date() + ": "+" Start
Reading");
try {
long size = upload.getSize();
BufferedReader fileReader = new
BufferedReader(new InputStreamReader(upload.getInputStream()));
ByteArrayOutputStream os = new
ByteArrayOutputStream();
int i;
int counter = 0;
while((i = fileReader.read()) != -1) {
counter ++;
os.write(i);
if(counter == 100) {
long osSize = os.size();
int p = Float.valueOf((100 * osSize)
/ size).intValue();
counter = 0;
if(p > percent) {
percent = p;
p = 0;
}
}
}
os.flush();
os.close();
System.out.println(new Date() + ": "+" File
read successfully");
} catch(IOException ie) {
VideoUploadPanel.this.error("There was a
problem uploading the file");
}
}
}
};
getRequestCycle().scheduleRequestHandlerAfterCurrent(
new ResourceStreamRequestHandler(writer);
....
...
}
The progress bar still does't get updated. Here is the response.. Note the
delay of 8 seconds marked in bold? Thats when the file is getting uploaded.

Any help / example would really be a life saver. I couldnt find much example
online on IResource and AjaxChannel
