How to get around File Upload Exception for Grails on Google App Engine?

Question

I am writing an application on Google App Engine using Grails. Everything works great on my local dev environment. However on live server, I get exception when trying to upload file. When Grails runtime tries to parse controller params, it uses Apache.Commons.FileUpload, which writes temp file and Google doesn't like it.

What is the best way to get around this without spending too much time?

Is there any way to skip parsing one of the request form items so that I can handle it manually through controller request object?

Answer 1

The solution is to use Google App Engine Virtual File System:

Answer 2

I want to use gaevfs with appengine and grails but cannot find any example. Anybody who has example of how to upload an image? And than fetch it and show in view.
