Oracle java7 config

  • 772

I've installed Oracle Java 7 according to this guide. When I run sudo update-java-alternatives -s java-7-oracle, it gives me :

update-alternatives: error: no alternatives for xulrunner-1.9-javaplugin.so.
update-alternatives: error: alternative /usr/lib/jvm/java-7-oracle/jre/bin/jexec for jexec not registered, not setting.
update-alternatives: error: alternative /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so for mozilla-javaplugin.so not registered, not setting.
update-alternatives: error: no alternatives for xulrunner-1.9-javaplugin.so.

What is the matter? I use ubuntu12.04 amd64.

12.04

    OPTION 1: Step by Step

    OPEN A TERMINAL WINDOW (uxterm or any other terminal emulator)

    Run as root

    sudo -i

cd /

    aptitude update

aptitude install python-software-properties

    Install Oracle java PPA

    apt-add-repository ppa:webupd8team/java

    Install Oracle java

    aptitude update

aptitude install oracle-java7-jdk oracle-java7-set-default oracle-java7-installer oracle-java7-plugin

    Fix know Oracle java issues: part 1. Make the dir "/usr/lib/xulrunner-addons/plugins/"

    mkdir -p /usr/lib/xulrunner-addons/plugins

    Fix know Oracle java issues: part 2. Register missing alternatives

    update-alternatives --install /usr/lib/mozilla/plugins/libjavaplugin.so mozilla-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so 1

update-alternatives --set mozilla-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so

update-alternatives --install /usr/lib/xulrunner-addons/plugins/libjavaplugin.so xulrunner-1.9-javaplugin.so /usr/lib/jvm/java-7-oracle/jre/lib/amd64/libnpjp2.so 1

    sed -i 's@jre jexec /usr/lib/jvm/java-7-oracle/jre/bin/jexec@jre jexec /usr/lib/jvm/java-7-oracle/jre/lib/jexec@g' /usr/lib/jvm/.java-7-oracle.jinfo

    Update java alternatives to make Oracle java to be the default java on system

    update-java-alternatives -s java-7-oracle

    Uninstall OpenJDK java files

    aptitude purge openjdk-7-jre openjdk-7-jre-headless openjdk-7-jre-lib default-jre default-jre-headless icedtea-7-jre-jamvm

    Logout from "root" user
