[ckan-dev] using a java client to upload files to a dataset created through the datahub.io website

[Sean Hammond]

Hey, I don't think CKANClient-J supports file uploading, although you
might try contacting rossjones about it.

You can upload files using the Python ckanclient though. As I recall
this wasn't simple to implement in Python ckanclient, the code that
handles it starts here, in case this is of any help to you:
