Image Download

[Halabe]

Hi,

I am trying to upload images from a GWT Module using FileUpload Widget
and a servlet.

When I try to see the image, using Image widget, by giving it the
public path of it's module, I am getting the error:
Resource not found: images/imagePath/Image1.jpg could a file be
missing from the public path or a <servlet> tag misconfigured in
module

However, the file is there and when I refresh the page, I can
visualize it.

How can I see the image without refreshing the page or how can I make
an automatic refresh of the page?

If the above is not possible, how can I set the image to be no
cachable?

Thank you for your help.
