      sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/java-7u9-jdk-i586/bin/java" 1
  sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/java-7u9-jdk-i586/bin/javac" 1
  sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/java-7u9-jdk-i586/bin/javaws" 1

  • Activate JDK tardets:

      sudo update-alternatives --config java
  sudo update-alternatives --config javac
  sudo update-alternatives --config javaws

  • Activate Java plugin for Mozilla (and Cromium as well):
