 10                    the Java platform. To run jEdit, you will a platform package
 11                    having a version number of at least 1.5.0_06. If you do not
 12                    have the Java platform, we recommend downloading the larger
 13                    &#8220;<span class="quote">Software Development Kit</span>&#8221; (SDK), instead of
 14                    the smaller &#8220;<span class="quote">Java Runtime Environment</span>&#8221; (JRE),
 15                    because you will need the tools supplied with the SDK if you
 16                    will be using Java for development. You will need to know
 17                    the path of the Java application launcher, which is called
 18                    <code class="filename">java.exe</code> on Windows systems and simply
 19                    <code class="filename">java</code> on others.</p><p>Next, decide whether you want the current stable
 20                    version or the latest development version. As a general
 21                    rule, the stable version is a good choice for first-time
 22                    users. However, jEdit 4.3pre7 has been in development for a
 23                    couple of years now, and it is definitely "stable" enough
 24                    for beginners. Download the Java installer for the version
 25                    you have chosen from the jEdit web site; it consists of a
 26                    single file with a name in the style
 27                    <code class="filename">jeditXXXinstall.jar</code>. This file is a
 28                    compressed archive containing all of the files you need for
 29                    jEdit to run as well as an installer application written in
 30                    Java. You can put this file anywhere on your hard disk that
 31                    is convenient.</p><p>To run the installer, do whatever you normally do to
 32                    run a Java jar archive. If this is your first time, follow
 33                    these steps:</p><div class="procedure"><ol type="1"><li><p>Open a terminal or command interpreter
 34                            window.</p></li><li><p>Change the current directory to the directory
 35                            in which you have stored the jEdit installer
 36                            file.</p></li><li><p>Run this command: <strong class="userinput"><code>[full path to java
 37                            application launcher] -jar
 38                            jeditXXXinstall.jar</code></strong></p></li></ol></div><p>The installer will load and display a series of
 39                    dialogs for selecting a few simple options, including the
 40                    directory in which you wish jEdit installed. It will also
 41                    tell you how much disk space you need for the main program
 42                    and various installation options.</p><p>If this is your first download of jEdit, you should
 43                    definitely install the set of macros that come with the
 44                    application. Many of them are useful for all programmers,
 45                    and even the ones you don't use can serve as models when you
 46                    eventually begin writing your own macros.</p><p>The installation process is very short. If you are
 47                    installing the program on Windows and you select the
 48                    jEditLauncher option, you should be able to start jEdit by
 49                    clicking on any of the icons that the installation program
 50                    provides. On other systems, you can enter
 51                    <strong class="userinput"><code>jedit</code></strong> in a terminal window or create
 52                    your own desktop or menu shortcut.</p></td></tr><tr class="question"><td align="left" valign="top"><a name="id2548997"></a><a name="java-web-start"></a><p><b>Q:</b></p></td><td align="left" valign="top"><p>Why is there no Java Web Start version of
