Hi everybody,
i've tried to update media files (csv files) directly to Mysql as
LongBlob through a Java client.
I' have made the update with 4 csv files and with two files all gone fine,
but with the other two files i get the following error in ODK COLLECT
client when i try to download them from the server...
Premature end of content - length delimited message body (expected 2808;
received 146)
Any ideas
Panos
Moving this to the dev list.
Directly manipulating data in the DB is a terrible idea. Once you go
down that path, it's going to be near impossible for anyone to help
undo. Any reason why you aren't using the API?

The wired thing is that if the same files trying to upload to Aggregate
with the traditional way all works fine ....
Thanks again..
Thread moved to dev list.

Note that if you are using a LONGBLOB, you need to increase your
communications buffer size in MySQL and restart the MySQL database server.
There was an older revision of ODK Aggregate that used LONGBLOB (v1.2) but
we reverted back to the default smaller blob size in v1.3 to avoid this
extra configuration step.
If you have a form definition, and want to update the media attachments for
it, you can simply re-upload the exact same form definition file with the
revised media attachments, and the server will replace them. I.e., you can
do a multi-part form data post to the server.
And -- we have a specific Java executable that does exactly that -- ODK
FormUploader, available on our downloads page.
You don't need to write or use your own API, or hack this action out of ODK
Briefcase.
If you want a command line interface to that tool, if you submit a code
change to add that, we will fold it into the next release (Nafundi, for
example, has contributed a CLI for Briefcase that will be in the upcoming
1.4.4 release).

Hi Yaw,i have create an automatic procedure that generate the csv files of
a XForm (every night).
I want with an batch procedure to upload the csv files as media files of
the XForm.
Tha XForm doesn't change but i want to change the media files...
Any help how to do this using the API ????
Thanks in advance
Panos
Panos,
As Mitch suggested, you should look at the ODK FormUploader. It uses
the API to upload media files and you'll need to do exactly that with
your system.
https://code.google.com/p/opendatakit/source/browse?repo=briefcase is
where the relevant code lives.
