I think I have this right, so hopefully to clarify: 1) You get the upload URL for an HTML form for your user to upload the image. Part of forming that uploading URL is to identify the handler code (e.g., Servlet in Java) 2) Your handler code gets called by the Blobstore after the upload is complete and that handler can work with the uploaded data and you'll work with the the key for the blob 3) Your handler sends a redirect command back to the user's browser directing them to the page they need to go to for status/results. That redirect URL generally includes a parameter identifying which blob upload (it's key) you're dealing with. 4) The user's browser is redirected to that page, where your code uses the blobstore key (from the URL parameter) to process and in your case return the OCR data.
So from the client point of view, they submit a forum with a file upload part, and they get redirected to the page that provides the results. Someone please correct if necessary. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
