I have following code to upload an image to server and I need servlet
to rename image to what the value of a hidden field sended to server
through a post method, the question is how to get the value of this
hidden field:imageStoreName.is it to use request.getParameter
("imageStoreName")?I tried it,but I got null.
private final void setUploader()
{
HorizontalPanel hpUploaderLayout = new HorizontalPanel();
// hidden will tell server how to rename the image
imageStoreName = new Hidden();
imageStoreName.setID("imageName");
imageStoreName.setValue(Util.getId());
final FileUpload uploader = new FileUpload();
........
hpUploaderLayout.add(imageStoreName);
hpUploaderLayout.add(uploader);
uploadForm.setWidget(hpUploaderLayout);
}
