Per creating an optimized geoserver build on my Linux(Ubuntu) server, I've tried to install JAI as an addition to my JRE.
Unfortunately, JAI seems to have disappeared from the Java website!
The JAI link seems to not be functional: http://download.java.net/media/jai/builds/release/1_1_3/ Same with JAI IO tools: https://jai-imageio.dev.java.net/binary-builds.html#Release_builds
Same with all those others on the documentation, and the other places I've found online.
Any word on the status of JAI? or any way to download JAI?
As is stated on JAVA considerations you can find them on OpenGEO
