my .java class

thanks !!!
i've encountered same issue. posting file succeeds 200 response, _files empty. fixed issue specifying content-length header. e.g.:
conn.setrequestproperty("content-length", integer.tostring(fileinputstream.available())); edit: so, when using this, file appeared in _files error code of 3. however, had call conn.setchunkedstreamingmode(1024);. removing content-length , call setchunkedstreamingmode worked me, i'm pretty sure empty _files content-length field not being set correctly.
