The easiest way to install the JDK 7 is to do it with the Web Up8 Oracle Java OOS. Hence this method no longer works and exists because of hostorical reasons. More information can be found on PPA's page on Launchpad. Thus this PPA doesn't have any Java files. Note: WebUpd8 team's PPA has been discontinued with effective from April 16, 2019. Then restart apparmor: sudo /etc/init.d/apparmor restart usr/lib/jvm/jdk*/jre/lib/*/libnp*.so cx -> browser_java, # /usr/lib/jvm/java-*-sun-1.*/jre/bin/java cx -> browser_java,

For Ubuntu 13.10, the path to the plugin directory is /usr/lib/firefox/browser/plugins/.ĭepending on your configuration, you might need to update the apparmor profile for Firefox (or other browsers) in /etc/apparmor.d/abstractions/ubuntu-browsers.d/java: # Replace the two lines:
N.B.: You can link the plugin ( libnpjp2.so) to /usr/lib/firefox/plugins/ for a system-wide installation ( /usr/lib/firefox-addons/plugins from 15.04 onwards). If you want to enable the Mozilla Firefox plugin: 32 bit: You need to set the new JDK as default editing the configuration file.
Repeat the above for: sudo update-alternatives -config javac Update-alternatives: using /usr/lib/jvm/jdk1.8.0/bin/java to provide /usr/bin/java (java) in manual mode Press enter to keep the current choice, or type selection number: 3 * 2 /usr/lib/jvm/jdk1.7.0/bin/java 1 manual modeģ /usr/lib/jvm/jdk1.8.0/bin/java 1 manual mode There are 3 choices for the alternative java (providing /usr/bin/java).Ġ /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 auto modeġ /usr/lib/jvm/java-7-openjdk-amd64/jre/bin/java 1071 manual mode You will see output similar to the one below - choose the number of jdk1.8.0 - for example 3 in this list (unless you have have never installed Java installed in your computer in which case a sentence saying "There is nothing to configure" will appear): $ sudo update-alternatives -config java This answer lists the other executables available. java, javac, javaws are probably the most frequently required. N.B.: Remember - Java JDK has many more executables that you can similarly install as above. Sudo chown -R root:root /usr/lib/jvm/jdk1.8.0 Be sure to use a higher priority if you want Oracle JDK to remain the default.Ĭorrect the file ownership and the permissions of the executables: This will assign Oracle JDK a priority of 1, which means that installing other JDKs will replace it as the default.
Sudo update-alternatives -install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.8.0/bin/javaws" 1 Sudo update-alternatives -install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0/bin/javac" 1 Sudo update-alternatives -install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0/bin/java" 1 N.B.: Check carefully this folder name since Oracle seem to change this occasionally with each update.
