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. OpenJDK Installation of Java Runtime Environment Install the openjdk-6-jre package using any installation method. Browser plugin Install the icedtea6-plugin package using any installation method. This plugin works with the browsers: Epiphany, Firefox and Opera. On Konqueror, go to Settings → Configure Konqueror... and from menu select Java & JavaScript, then tick Enable Java globally option. OpenJDK v6 & v7 SDK (Software Development Kit) In Java parlance the Java Development Kit (JDK) is sometimes used for SDK. Install the openjdk-6-jdk package using any installation method. Alternative Virtual Machines Most users won't need to worry about these, but if you use an architecture (e.g. JamVM: This is the default VM for ARM in 11.10. Oracle Java 7 Script (JRE only) Related:  Install Java about GNU/Linux (ubuntu 12+) & browser (FF/Chrome)

Install Oracle Java 7 in Ubuntu via PPA Repository Update: Java 7 is no longer supported by Oracle. The binaries are no longer available for download, but if you have an Oracle account, you can still download it after logging in. The Oracle Java 7 installer in this article will continue to work only if you manually download Oracle JDK 7 (version 7u80 for 32bit and 64bit or 7u60 for arm), place it in the /var/cache/oracle-jdk7-installer/ folder on your computer, then install "oracle-java7-installer" as explained below in this article. We've previously written about installing Oracle JDK 7 in Ubuntu using a script with a GUI provided by Zenity. 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! Update: our Oracle Java 7 installer now supports ARM.

Main Page 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. Note: For Firefox version 21 and higher, you must create the symbolic link in your home directory, ~/.mozilla/plugins. This release provides the Next-Generation Java plugin. The locaton of the plugin file for Linux varies according to the chip architecture of the underlying platform. If you are using a 32-bit Firefox, you should use the 32-bit Java Plugin (from the lib/i386 directory). To install the Java Plugin follow these steps: 1. 2. Only one Java Plugin can be used at a time. 3. For a 64-bit Plugin:

Evolution of shells in Linux From Bourne to Bash and beyond M. JonesPublished on December 06, 2011/Updated: December 09, 2011 Connect with Tim Tim is one of our most popular and prolific authors. Shells are like editors: Everyone has a favorite and vehemently defends that choice (and tells you why you should switch). My first experience with a modern shell came in the 1980s, when I was developing software on SunOS. Let's begin with a short history of modern shells, and then explore some of the useful and exotic shells available for Linux today. A history of shells Shells as little languages Shells are specialized, domain-specific languages (little languages) that implement a specific use model—in this case, providing an interface to an operating system. Shells—or command-line interpreters—have a long history, but this discussion begins with the first UNIX® shell. The shell introduced a compact syntax for redirection (< > and >>) and piping (| or ^) that has survived into modern shells. UNIX shells since 1977 Figure 1.

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. Some Linux distributions search additional directories to handle the Adobe Flash player plugin or to support 32-bit plugins in a 64-bit environment. null plugin location Firefox installs a default plugin named "". find / -name -print Fedora Core 3/4 Where Firefox has been installed with the FC3/FC4 distribution, /usr/lib/firefox-<version>/plugins where <version> is a numeric reference to the version e.g.

[How to] Never Miss an Ubuntu Notification Have you ever missed a notification pop-up in Ubuntu? I have, and whilst Notify OSD – the proper name for the alert delivery system used in Ubuntu – can hardly be called a ‘blink and you miss it’ affair, it is, still, possible to miss notifications whilst you’re off making coffee or tending to a harem of guinea pigs. That’s where this ‘Recent Notifications’ applet comes into play. The service it provides is simple enough: it logs all notifications that show up on your screen – whether you act on them or not. Useful? I’m struggling to find a use case of my own in which I’d need to see missed notifications (Chat, Gwibber etc are all stored in the Messaging Menu for example) but if I am on the look out for gaining a more detailed report of a missed notification (such as an IRC message) then this applet would certainly be helpful.

Desktop file specification extension | GrumZ.Net Introduction This is DES-EMA, the Extension for Menus and Actions of the Desktop Entry Specification (DES). This specification aims to define a common format for user actions, allowing creators to share their actions between compliant desktop environments. This also covers how actions may be organized in a hierarchy of menus, submenus, and so on. It explains how actions and menus should be described in .desktop files, how and where these .desktop files are to be searched for, and how the final hierarchy should be built. This specification doesn't explicitly handle the « level-zero » case (but see the appendix A for a proposition about that). Such an extension, targeting action items in file manager context menu, has been widely discussed in KDE, and Thunar lists. This is version 0.15 of our draft, updated on 2010, November 23rd (see ChangeLog below). Desktop file Desktop file format This specification relies on the common syntax defined in DES.

installation - How do I install Oracle Java JDK 7 jcontrol (about oracle) Install Oracle Java 8 In Ubuntu Via PPA Repository [JDK8] The Oracle JDK License has changed for releases starting April 16, 2019.The new Oracle Technology Network License Agreement for Oracle Java SE is substantially different from prior Oracle JDK licenses. The new license permits certain uses, such as personal use and development use, at no cost -- but other uses authorized under prior Oracle JDK licenses may no longer be available. Please review the terms carefully before downloading and using this product. An FAQ is available here.Oracle Java downloads now require logging in to an Oracle account to download Java updates, like the latest Oracle Java 8u211 / Java SE 8u212. Because of this I cannot update the PPA with the latest Java (and the old links were broken by Oracle).For this reason, THIS PPA IS DISCONTINUED (unless I find some way around this limitation). Oracle Java 8 is now stable. As a reminder, the WebUpd8 Oracle Java PPA doesn't include any Java binaries, just a script that automatically downloads and install Oracle Java 8.

How to install the Oracle JDK on Debian 8 First, a little background Several years ago Debian and its downstream derivatives (like Ubuntu) stopped providing packages for Oracle's JDK in their respective repositories. While OpenJDK is typically available and works well, it is sometimes desirable to use the official Oracle JRE/JDK (especially if a support contract dictates its usage). So if Oracle's JDK isn't available in the standard repositories how does one go about installing it? One option is to use an unofficial third-party repository which provides the JDK in a compatible package. Installing the java-package package Installing the java-package package, along with several required dependencies, can be done using either apt-get or aptitude, depending on preference. Please ensure that you have the contrib repository enabled before proceeding! Install using apt-get user@host:~$ apt-get install -y java-package libxslt1.1 libgl1-mesa-glx libxtst6 libxxf86vm1 Or install using aptitude Building the custom JDK package That's it!
