Overview Sun Microsystems have developed Java, which is many things depending on who you ask. It is a language, and an execution environment and probably many more things. On this page Java refers to the software that executes programs compiled to Java byte codes (akin to machine language). Be aware of the Java trap. Although keep in mind that with the GPL licensing of the Sun Java implementation the Java trap is a thing of the past. Even RMS thinks so. Use IcedTea on Ubuntu 7.10 and OpenJDK on Ubuntu 8.04 or later. The first free project to offer substantial parts of Java platform functionality was Guavac. After that the free software movement developed java compilers, most notably the GNU Compiler for Java. GCJ is a front end to the GCC compiler which can natively compile both Java(tm) source and bytecode files. The compiler can also generate class files. Gcjwebplugin is a little web browser plugin to execute Java applets. It is targeted for Mozilla and compatible browsers that support the NPAPI. Others include the Eclipse Java Compiler, which is maintained by the Eclipse Foundation. Eclipse is an open-source Integrated development environment (IDE) written primarily in Java. The Eclipse open source community has over 60 open source projects. OpenJDK is the open source Java, derived from sources which will become OpenJDK 7 in the future.

Running Java under Ubuntu In order to run Java programs and Java applets, you must have a Java environment installed. The GCJ flavor of Java is installed as default, and is usually fine for most purposes. If it is not installed, JavaInstallation describes how to install some opensource flavors of Java. You may, however, have a need to run the Sun flavor of Java if something does not work correctly. To get Sun Java under Ubuntu 7.04 or later running on Intel or PowerPC platform, you should enable the Universe repository in Add/Remove programs, and install either the openjdk-6-jre package or the sun-java6-bin package. (Note: PowerPC version is slow). To get Sun Java under Ubuntu 6.06 or 6.10 running on Intel x86 platform, you should enable the Universe repository in Add/Remove programs, and install the sun-java5-bin package. Note: The same commands will work under Xubuntu/Kubuntu (using Add/Remove or the Adept Package Installer). Choosing the default Java to use Just installing new Java flavours does not change the default Java pointed to by /usr/bin/java. You must explicitly set this: * Open a Terminal window * Run sudo update-java-alternatives -l to see the current configuration and possibilities. * Run sudo update-java-alternatives -s XXXX to set the XXX java version as default. For Sun Java 6 this would be sudo update-java-alternatives -s java-6-sun * Run java -version to ensure that the correct version is being called. You can also use the following command to interactively make the change; * Open a Terminal window * Run sudo update-alternatives --config java * Follow the onscreen prompt

Home Face-to-Face Local Support Our worldwide network of Local Community ("LoCo") teams is providing a strong backbone to our already vast and extensive Ubuntu community. Many of these teams provide free, face-to-face local support, such as one-on-one troubleshooting, group sessions, and presentations about Ubuntu. Why not go and see the full list of teams!

You are welcome to join one of these or start your own. An important part of the Ubuntu manifesto is your ability to use your software in your local language. Part of that is ensuring that Ubuntu includes the best translations available for the Ubuntu desktop software (and you can help to improve those translations). Another part of that commitment is helping to create mailing lists and IRC channels for Ubuntu users in different languages.

The Terminal is Your Friend Perhaps the most powerful tool in Linux is your Terminal Program. Before you jump in, take a moment to familiarize yourself with the command line--your invaluable asset in Linux. FAQs Still have questions? You are not alone. Stop by the most common questions that new Ubuntu users frequently ask.

Exploring the Repositories There are several gui-based methods you can use to explore the repositories. One is to open Synaptic and click on the Origin button. This will display a repository list in the window above the button. The list will contain all the repositories enabled in your sources.list. To the right will be the packages available via download (white boxes) and currently installed packages (green boxes). There are two images of the main Synaptic page below. The first, on the left, shows the results of selecting local/main. Local packages are packages stored on the user's computer. The second example, on the right, displays the results of selecting the Ubuntu main online repository.

Internet Relay Chat (IRC) is a form of realtime Internet chat. It is mainly designed for group (many-to-many) communication in discussion forums called channels, but also allows one-to-one communlication via private message. On IRC you can talk to many other members using Ubuntu, on topics ranging from idle chit-chat to support with your Ubuntu. Though a channel might have many people in it at any one time, they might not always be at their keyboard; so if no-one responds, just wait around and someone will hopefully answer soon enough. This page serves as an information base for users of the Ubuntu IRC channels. The Ubuntu channels can be found on the Freenode network, irc.freenode.net. xchat in Ubuntu has this network preconfigured and the main channel, #ubuntu, will automatically be joined. Kubuntu also comes with Konversation, which is also pre-configured for the Kubuntu help channels. When participating in Ubuntu IRC channels, please abide by the Code of Conduct and channel guidelines.

General Upgrade Information

Categories of software in Ubuntu The thousands of software packages available for Ubuntu are organised into three key components: main, restricted and universe. Software is published in one of those components based on whether or not it meets our Free Software Philosophy, and the level of support we can provide for it. You can read about these components in more detail here. This policy only addresses the software that you will find in main and restricted, which contain software that is fully supported by the Ubuntu team and must comply with this policy. In the universe component you will find just about every other piece of software you can imagine, under a huge variety of licenses... really the full software universe. If you install software from universe please ensure you take the time to check the license for yourself. All software in Ubuntu main and restricted must be licensed in a way that is compatible with our license policy. There are many definitions of 'free' and 'free software' so we have included our own set of guidelines.

To find out what kind of software modem you are using, go to linmodems.org, read the page, and download the scanModem tool (which will only recognize PCI and USB modems, not ISA modems). Copy it to your desktop in your Ubuntu machine, then open a command line and enter:

This page is designed to help you set up the driver, and configure your dial-up connection over a modem. If you need information about modems, see Modems. If you need to buy a new modem, see the appropriate section at Discussion.
