Has anyone implemented a solution to upload files to google docs (under google apps domain) from a grails application?
What is the recommended approach?
Did you use any of the Grails file upload plugins?
Did you have to configure anything on the google apps account to allow you to upload files?
I haven't heard of a plugin, but you can use the Google API client: https://code.google.com/apis/documents/
I haven't this particular library, but I've used the one for managing calendars and the one for Google Analytics. Their APIs are very well documented and have lots of sample code, so it should be easy to get started.
