JPEG2000 files not working with openjpeg

[michaelw3]

Hi, first of all thanks for this great server!

I compiled it on an OpenSUSE Leap 42.3 with openjpeg enabled, though i'm not able to load jp2 files from the server. while trying to access the jp2 through IIIF protocol i get a 400 Error, bad request. i tried also with TIF file and it's working good.

also i'm not able to write to the log file i created in /var/log/iipsrv.log would be thankful for any help. Michael

Wrong permissions? The log file must be writable by the web server process.

Maybe it didn't properly compile the openjpeg code. Make sure you get the log file working in order to properly diagnose. Also make sure it says openjpeg has been found at the end of the ./configure script

thanks @stweil and @ruven for the answers, I'm not quite sure how to get the right permissions for the log file, i think that just for the test i'm going to open for read and write to everyone.. i did compile it with openjpeg and get it showed it in the compile script as found.. now i can see the jpeg but when i try to load more than a few files at once somehow it won't work anymore and i get a 500 error, this occurs also with TIFF files, is this a sort of restriction and can i change that in the options?

finally got the log to work, i guess not the safest method but it works for now.. here is the last snippet from the log i don't see anything suspicious, do you?

Nor do I.

Your iipsrv log looks fine. A 500 error is something issued by your web server (Apache or whatever). Maybe there's more information in the web server error log file?
