Hello Bjorn,
from what I see, you are following the right way (see
http://www.restlet.org/documentation/2.1/jse/ext/org/restlet/ext/fileupload/RestletFileUpload.html#getItemIterator%28org.restlet.representation.Representation%29
)
Best regards,
Thierry Boileau
ps : there could be another way using the FormDataSet class taken from the
org.restlet.ext.html extension. But there's something I miss about the aim
of this class. I check with Jérôme.
