icedtea-web 1.6.2 does not seem to work with SuperMicro’s IPMI Java iKVM viewer. SuperMicro’s helpful response is to only use Oracle’s Java.
net.sourceforge.jnlp.LaunchException: Fatal: Initialization Error: Could not initialize application. The application has not been initialized, for more information execute javaws from the command line.
Even when you have the right version of Java you often have to dance through security hoops or Java versions just to get it to work.
If you have Docker installed there is a great solution that avoids installing Oracle’s Java and/or tweaking any security settings. solarkennedy has created a very nice Docker container that encapsulates everything needed to access various Java based IPMI consoles.
docker run -p 8080:8080 solarkennedy/ipmi-kvm-docker
Now point your browser to http://localhost:8080 and voila:
You are looking at a Java enabled Firefox (and OS) through a web VNC client accessed from the Docker host. Not bad!
