Hi there,

Djakota fills a need of a project I'm working on, but the long time 
since the last release, and low volume on the mailing list makes me 
wonder if it is abandoned.

I also have a problem with the current 1.1 server (adora-djakota) and 
2.0 viewer (based on iipimage). It works with the big sample images from 
the demos, but when I try with my own small images, which comes from 
medical CT and RT equipment, I get tons of erros such as:

127.0.0.1 - - [23/May/2012:18:47:33 -0300] "GET 
/adore-djatoka/resolver?url_ver=Z39.88-2004&rft_id=info%3Alanl-repo%2Flabs%2F1&svc_id=info:lanl-repo/svc/getRegion&svc_val_fmt=info:ofi/fmt:kev:mtx:jpeg2000&svc.format=image/jpeg&svc.level=3&svc.rotate=0&svc.region=0,-1536,256,256 
HTTP/1.1" 404 952

This came from Tomcat access logs. The error log (catalina.out) shows 
nothing.

It looks like the viewer is in loop trying to get a non-existant segment 
of the image.

If I try requesting this same region using the adore-djakota server test 
pages, I get the same error. But if I ask for other regions (positive 
values), it works fine. I guess either the viewer has to be fixed to 
work with "small images" or the server could send am empty (all back or 
the like) jpeg as response.

Access logs also shows that a big image generates lots of requests, but 
never a negative value as part of the region.

I wonder if I can get new code from the iipimage project to fix this, or 
if the code included on the viewer was patched to talk to adora-djakota.
