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

Why? "Under Linux there are GUIs (graphical user interfaces), where you can point and click and drag, and hopefully get work done without first reading lots of documentation. The traditional Unix environment is a CLI (command line interface), where you type commands to tell the computer what to do. That is faster and more powerful, but requires finding out what the commands are." -- from man intro(1) For some tasks, especially things like system configuration, it makes sense to use the terminal, and you'll probably have seen instructions on help pages or forums similar to:

Wired troubleshooting If you have a network connection which is not working properly, you can use a few tools to help diagnose what the problem is. Most of the tools in this section require use of the Terminal, which you can open by pressing Applications → Accessories → Terminal. Get information about the current connection ifconfig is intended to allow you to change the settings of your network connections, but it can also be used to list information about the current connection. 1. Press Applications → Accessories → Terminal to open a Terminal 2. Type ifconfig eth1 in the Terminal and press Enter, replacing eth1 with the name of your network interface if it is different. * inet addr gives the current IP address of the connection * HWaddr gives the MAC address of your network device

Documentation for Ubuntu 9.04 This site is where you can find the official documentation developed and maintained by the Ubuntu Documentation Project. This page contains documentation for Ubuntu 9.04, the latest stable version, released in April 2009. If you can't find what you are looking for here, try the excellent source of community contributed documentation.

If you have been a Windows and/or a Mac OS user to date, you are probably used to searching for a program on the internet (often offered in an executable installer) and having to download and install it. You're probably familiar with software distributed on CDs, DVDs, etc. which often have an autorun feature from where you can then install them. For free and open systems like Ubuntu GNU/Linux there is some software distributed in this fashion, but those are mostly proprietary and closed programs.
