Question

When i submit upload form, following error is displayed. How can i solve it?

404 Not Found The resource could not be found.

python code

class DashboardHandler(webapp2.RequestHandler):
    def get(self):
        upload_url = blobstore.create_upload_url('/upload')

class UploadHandler(blobstore_handlers.BlobstoreUploadHandler):
    def post(self):
        upload_files = self.get_uploads('file')
        blob_info = upload_files[0]
        self.redirect('/serve/%s' % blob_info.key())

app = webapp2.WSGIApplication([
    ('/(mysitename)/upload', UploadHandler),
debug=True)

HTML(template)

<form action={{upload_url}} method="post" enctype="multipart/form-data">
  <input type="file">
  <input type="submit" name="UPLOAD">
</form>

You don't give many details so it is hard to diagnose. Are you using a blobstore_handlers.BlobstoreUploadHandler instead of the regular RequestHandler? If so, please show that handler and the relevant portion of your WSGIApplication setup.
