Unable to fetch image data using URL

Development
1

Hi,

I am trying to fetch signature image (binary) data contained in the form
submission. I am using Tomcat and MySQL for ODK aggregate. I referred to
the
https://groups.google.com/forum/?fromgroups=#!searchin/opendatakit-developers/binary$20url/opendatakit-developers/sijorgwMtGA/pq8d6OFJJn4J URL
and created a URL as follows :

http://localhost:8080/ODKAggregate/view/binaryData?blobKey=avddvr_19[@version=null
and
@uiVersion=null]/bmnote[@key=uuid:0fba2b67-923c-414d-96d5-a0dbef5b291]/Review_BM:BM_Sign_BM

I also set the "Allow anonymous retrieval of images, audio and video data
(needed for GoogleEarth balloon displays)" permissions. Now when I browse
to the above URL, I get "Unable to retrieve attachment" and also in tomcat
console I get following :

Caused by:
org.opendatakit.common.persistence.exception.ODKEntityNotFoundExcepti
on: Unable to retrieve odk_prod.AVDDVR_19_CORE key:
uuid:0fba2b67-923c-414d-96d5
-a0dbef5b291

What may be the problem?

Please let me know.

Hi,

Do I need to URLEncode? Just a guess.

THe easiest way to debug this is to go to the submissions page and
right-click on one of these signature images, and compare the URL you are
constructing with the URL you can copy with the right-click.
