What can be done to fix this?

Thanks!

In order to have gwtupload working in Google AppEngine you have to use
both gwtupload and gwtupload-gae libraries, your servlet has to
extend AppEngineUploadAction, and you have to store files in
DataStore, and be aware that GAE has several limitations like:

The request size is limited to 512 KB, so you only can upload small files.
The time spent to process a request is limited.

Cheers
