How to run Java 8 JNLP on IcedTea?

[rtek1000]

Hello,


I managed to run the application correctly on Windows 10, but I can't on Linux.


I discovered on the internet that IcedTea is necessary to run the *.jnlp file, and it seems that the currently available version (icedtea-next) only works with Java 11.


But it looks like this *.jnlp application I'm trying to run works only with Java 8.

Does anybody know how to solve this?


I tried several tips, but they seem to be out of date.

Version of Linux (Xubuntu) I'm running:

$ cat /etc/os-release
NAME="Ubuntu"
VERSION="20.04.2 LTS (Focal Fossa)"
ID=ubuntu
ID_LIKE=debian
PRETTY_NAME="Ubuntu 20.04.2 LTS"
VERSION_ID="20.04"

UBUNTU_CODENAME=focal



Thank you.

It's icedtea-netx, not icedtea-next.

Do you have a Java Runtime Environment for Java 8 installed (package openjdk-8-jre, might need some others ...) ? Have you tried setting that as the default Java using update-java-alternatives ('update-java-alternatives -l' to get a list, 'sudo update-alternatives -s <name of the jre to set as default >' to set a default JRE) ?
