Fernando,
There's nothing specific about the generic tapestry form. If you look at
the stacktrace, the problem comes from Commons Fileupload trying to use a
temp file to store the file upload. There is a version of Commons Fileupload
that is GAE friendly, google it and you'll be able to get it working.
Cheers,
Alex K
