How to upload images to appengine from gwt

Related question I am having similar problems to what that guy had in his. My upload server returns a redirect.

Specifically, I am not sure what FormPanel.SubmitCompleteEvent.getResults() returns. Sometimes, I get html of an img:

<img style="cursor: -moz-zoom-in;" 
    alt="http://<myapp>.appspot.com/servePic?blob-key=abcdef"
    src="http://<myapp>.appspot.com/servePic?blob-abcdef"
    height="1" width="1">

Sometimes I get the image data in bytes. Behavior varies on I dunno what. I get the first开发者_开发技巧 in development, and the second in production.

Does anyone know anything about this?

Here's a pretty good example of how to save/load/resize images with gwt & app engine.

Have a look in the dao implemenations and also the gwt interface packages.

Does the project in this link still exists?

I tried to checked it out through eclipse but looks like it does not exist anymore.
