I had some problems accessing my HP server’s remote console.
I’m using Debian 9.5.. with OpenJDK-8.. it just dont work. I found a workaround so I would like to share it with you!
1. Download Java SE Runtime Environment 8
2. Extract and move it to /opt (as root)
tar -zxvf jre-8u181-linux-x64.tar.gz
mv jre1.8.0_181 /opt/
3. Download .jnlp file by clicking “Java Web Start”
javaws and follow the dialogs.
Optional. You can also associate the .jnlp with /opt/jre1.8.0_181/bin/javaws.
