I was installing JAI and JAI Image, when I follow the documentation from Geoserver, the JAI work ok, without problems, but when I install JAI Image with the commands, from jdk8 folder (location) as the documentation from geoserver:
$ export _POSIX2_VERSION=199209 $ sh jai_imageio-1_1-lib-linux-i586-jdk.bin accept license_
the install is correct, but when i start Geoserver, it show the error message:
http error: 404 problem accessing /geoserver/. reason: not found
I can't access to Geoserver, i have to re install Java (Rollback), then the Geoserver working correctly.
