Launching the VNC Console in Oracle VM Manager on a Linux client

In Oracle VM Manager you can connect to a running virtual machine using a Java VNC client.

VM's Console

If you use Firefox on Linux, with the IcedTea Java plugin installed, the VNC console won’t start. It will give an error message saying failed “parsing the JNLP file”. The solution is simple: you should open the JNLP file with a “real” JRE/JDK.

If you don’t a Oracle JRE/JDK present, simply download the tar.gz distribution to a directory, and edit your Firefox profile.

Open mimeTypes.rdf in ~/.mozilla/firefox/<some weird string>/ and change the following configuration:

  <RDF:Description RDF:about="urn:mimetype:externalApplication:application/x-java-jnlp-file"
     NC:path="/path-to-your-java-installation/bin/javaws"
     NC:prettyName="javaws" />

The NC:path should point to your Oracle Java home’s javaws executable. Restart your browser, and you’ll be fine.
