Hi Jerome,
Thanks very much for replying my post ... i got over my problem by checking
the referrer to the FileUpload resource as follows:
@Override //==> at FileUploader resource
public void acceptRepresentation(Representation entity)
throws ResourceException {
try {
//==> Get uploaded File & Save it
UploadFile(entity);
//==> Check if Referrer to this resource was the main page (html
interface restlet) then redirect to it
// again so we can avoid the refresh page resubmission issue
and update
// display if upload performed successfully
if (getRequest().getReferrerRef() != null) {
getResponse().redirectPermanent("/myrestlet/main_interface");
}else {
//==>> i.e. no referrer from html main page though upload
was done directly by posting the file on this resource (using curl for
example). Reply file uploader with a message
getResponse().setEntity("file successfully received",
MediaType.TEXT_PLAIN);
}
}
Thanks again Jerome,
Best Regards
