Installation - How do I install Oracle Java JDK 7
There is a similar answer on how to install JRE 8. The manual way Download the 32-bit or 64-bit Linux "compressed binary file" - it has a ".tar.gz" file extension.Uncompress it tar -xvf jdk-8-linux-i586.tar.gz (32-bit) tar -xvf jdk-8-linux-x64.tar.gz (64-bit) The JDK 8 package is extracted into ./jdk1.8.0 directory. N.B.: Check carefully this folder name since Oracle seem to change this occasionally with each update. Now move the JDK 8 directory to /usr/lib sudo mkdir -p /usr/lib/jvm sudo mv . Now run sudo update-alternatives --install "/usr/bin/java" "java" "/usr/lib/jvm/jdk1.8.0/bin/java" 1 sudo update-alternatives --install "/usr/bin/javac" "javac" "/usr/lib/jvm/jdk1.8.0/bin/javac" 1 sudo update-alternatives --install "/usr/bin/javaws" "javaws" "/usr/lib/jvm/jdk1.8.0/bin/javaws" 1 This will assign Oracle JDK a priority of 1, which means that installing other JDKs will replace it as the default. Run sudo update-alternatives --config java Repeat the above for: Note for NetBeans users! Source #!

Install Oracle Java 7 in Ubuntu via PPA Repository We've previously written about installing Oracle JDK 7 in Ubuntu using a script with a GUI provided by Zenity. Some may find this method hard to use and also, it comes with GTK dependencies. So as an alternative that doesn't have any GTK dependencies and comes with automatic updates too, I've set up an Ubuntu PPA for the latest Oracle Java 7 (JDK). The PPA should work not only with Ubuntu but also Linux Mint and other Ubuntu-based Linux distributions. If you really need to use Oracle (ex Sun) Java instead of OpenJDK in Ubuntu, here's an easy way to do it: a PPA repository to install and keep your computer up to date with the latest Oracle Java 7 (Java JDK which includes JRE). Please note that this package is currently in alpha and is offered without any guarantees, so it may or may not work!

How to build a 40TB file server The one most valuable asset at is our photo collection. Take away the intellectual property and what’s left is, essentially, markup (with a bit of backend to snazz it up.) So we need a solid backup solution for the original high-res photos. The old servers were about to run out of capacity and their slightly outdated specs did not make transferring huge datasets any easier or faster. USB Installation Media Startup Disk Creator Ubuntu distributions from 8.04 'Hardy' onwards have 'Startup Disk Creator' a usb-creator tool that creates a bootable USB flash drive from a Ubuntu CD or iso image. Most users should use Startup Disk Creator or Unetbootin instead of many alternatives described here that perform similar steps. Current Ubuntu versions can also be cloned directly from the iso file to a USB drive. See Installation/FromUSBStick.

Java Introduction Java is a technology originally developed by Sun Microsystems, and acquired by Oracle. The following are the prevalent implementations: OpenJDK: The OpenJDK project is an open-source implementation of the Java SE Platform. This is the default version of Java that is provided from a supported Ubuntu repository. TimeMovedBackwards - Dovecot Wiki Dovecot isn't very forgiving if your system's time moves backwards. There are usually two possibilities why it's moving backwards: You're running ntpdate periodically. This isn't a good idea. Try Ubuntu before you install it You can try Ubuntu without actually installing it on your computer’s hard drive. You can do this by starting up your computer with either an Ubuntu DVD in the drive or a USB stick with Ubuntu on it in a USB port. Here’s how: 1 Using a DVD?Put the Ubuntu DVD into the DVD-drive and restart the computer.

Java Plugin on Linux See JDK 7 and JRE 7 Installation Guide for general information about installing JDK 7 and JRE 7. When you install the Java platform, the Java plugin file is included as part of that install. If you want to use Java within Firefox, you need to manually create a symbolic link from the plugin file in the release to one of the locations that Firefox expects. To make the plugin available to all users, create the link inside of the Firefox application's directory, in the plugins subdirectory. Alternatively, you can create the symbolic link in your home directory, in ~/.mozilla/plugins. In the remainder of this document, the text, "Firefox plugins directory", implies either of these locations.

HTTPD - Apache2 Web Server Apache is the most commonly used Web Server on Linux systems. Web Servers are used to serve Web Pages requested by client computers. Clients typically request and view Web Pages using Web Browser applications such as Firefox, Opera, or Mozilla. Determining plugin directory on Linux From MozillaZine Knowledge Base Plugin path Mozilla applications on Linux consult several directories looking for plugins. The exact list depends on how the application binary was compiled and packages, but can include directories such as $HOME/.mozilla/pluginsprogram_directory/plugins/usr/lib/mozilla/plugins/usr/lib/xulrunner/plugins where $HOME is the user's home directory and program_directory is where the Mozilla application binary resides.
