Introduction

Proxmox VE Java console does not work with old icedtea-plugins on Ubuntu, Debian and other distros. Latest icedtea-7-plugin (1.4-3 or higher) works, for more details see http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=707729

Best practices, use Oracle (Sun) 7 version to get the console correctly working.

Solution

Debian Wheezy (and later) and OpenJdk 7

# aptitude install openjdk-7-jre icedtea-7-plugin

(will install also icedtea-netx) I had errors in starting console until I removed 'openjdk-6-whatever' and 'icedtea-6-whatever', included 'icedtea' (generic package that brings version 6)

shell script to update-sun-jre

  • check http://www.duinsoft.nl/packages.php?t=en , there is a shell script and a repository which make the installation of the Oracle (Sun) Java Runtime Environment very easy. I used it on Ubuntu, but it look like it'll work on any Debian based system.

On that link there is information about the java changes that occurred in August 2011.

Solution for Ubuntu 12.04 and Oracle Java 7

first method, leaving openjdk installed: http://askubuntu.com/questions/183867/how-do-i-update-oracle-java-7-jdk-and-jre

$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java7-installer
$ sudo update-java-alternatives -s java-7-oracle

second method, removing openjdk: http://askubuntu.com/questions/143781/used-purge-command-to-remove-java-it-removed-a-lot-more-than-java

$ sudo apt-get purge openjdk*
$ sudo add-apt-repository ppa:webupd8team/java
$ sudo apt-get update
$ sudo apt-get install oracle-java7-installer

Remember that, contrary to OpenJDK, Oracle Java is *not* Free Software, and no one except Oracle has control on the code and knows what really does on your computer.
