According to your listing you have the jai-imageio-jpeg2000 JAR files
that contains the codecs for JPEG 2000.

Is the TIFF codec listed on /server/dlConfig.jsp? If not then all
ImageIO-Plugins refused to load.

I remember that some versions of Tomcat refused to load ImageIO-Plugin
JARs from the webapp directory, you can read about it in "Installing JAI
ImageIO" on <http://robcast.github.io/digilib/java-settings.html>.

The normal jai-imageio-jpeg2000 plugin should be able to read JPEG2000
files. The performance is not very good though. If you need better
performance you can try out the <https://github.com/dbmdz/imageio-jnr>
plugin which needs the installation of native libraries. You can try it
out if you build the latest digilib sources with "mvn -Dimageio=jnr". I
did not test these codecs much but I would be interested in reports how
it goes :-)

I hope that helps

	Robert
