Hi Buminda. Is your code similar to CHEN's above? It looks like he's trying to use the Blobstore service in the context of a framework -- are you doing something similar? If so, can you please provide your servlet/controller source and mappings? Also, what is the URL in your address bar when you see this exception? Does it look similar to http://<APPID>. appspot.com/_ah/upload/<KEY> or is it redirecting successfully to your handler (/story_add.do in CHEN's example)? Finally, can you confirm whether you see the new blob in the Admin Console's Blob Viewer?
