You can try using oracle jdk. - Install oracle jdk by downloading the rpm from oracle. (I used version 1.8) - Configure your browser to use the javaws provided by oraclejdk for .jnlp files. - The javaws binary can usually be found in a location like /usr/java/jdk1.8.0_181-amd64/bin/javaws - Note: Downloading and running the jnlp from cli doesn't seem to work, it has to be passed to javaws by the browser. - In Firefox: Preferences > Applications > jnlp (Sometimes this doesn't appear until the first time you try to open a jnlp with firefox, and you may have to manually navigate to the javaws binary path) On Fri, Nov 15, 2019 at 10:18 AM Sachidananda URS <surs(a)redhat.com&gt; wrote:
