 21        What is the easiest way to install jEdit?
 22      </para></question>
 23      <answer><para>
 24        First, make sure you have a working installation of the Java platform.
 25        To run jEdit, you will a platform package having a version number of at least 1.3.
 26        Versions 1.3, 1.3.1 or 1.4 will all work. If you do not have the Java platform,
 27        we recommend downloading the larger <quote>Software Development Kit</quote> (SDK), instead of
 28        the smaller <quote>Java Runtime Environment</quote> (JRE), because you will need
 29        the tools supplied with the SDK if you will be using Java for development.
 30        You will need to know the path of the Java application launcher, which is
 31        called <filename>java.exe</filename> on Windows systems and simply
 32        <filename>java</filename> on others.
 33      </para>
 34      <para>
 35        Next, decide whether you want the current stable version or the latest
 36        development version. The stable version is a good choice for first-time
 37        users. Download the Java installer for the version you have chosen from
 38        the jEdit web site; it consists of a single file with a name in the
 39        style <filename>jeditXXXinstall.jar</filename>.
 40        This file is a compressed archive containing all of the files you need
 41        for jEdit to run as well as an installer application written in Java.
 42        You can put this file anywhere on your hard disk that is convenient.
 43      </para>
 44      <para>
 45        To run the installer, do whatever you normally do to run a Java jar
 46        archive. If this is your first time, follow these steps:
 47      </para>
 48      <procedure>
 49        <step><para>Open a terminal or command interpreter window.</para></step>
 50        <step><para>Change the current directory to the directory in which you
 51        have stored the jEdit installer file.</para></step>
 52        <step><para>Run this command:
 53          <userinput>[full path to java application launcher] -jar
 54          jeditXXXinstall.jar</userinput></para>
 55        </step>
 56      </procedure>
 57      <para>
 58        The installer will load and display a series of dialogs for selecting a
 59        few simple options, including the directory in which you wish jEdit
 60        installed. It will also tell you how much disk space you need for
 61        the main program and various installation options.
 62      </para>
 63      <para>
 64        If this is your first download of jEdit, you should definitely install
 65        the set of macros that come with the application. Many of them are
 66        useful for all programmers, and even the ones you don't use can
 67        serve as models when you eventually begin writing your own macros.
 68      </para>
 69      <para>
 70        The installation process is very short. If you are installing the
 71        program on Windows and you select the jEditLauncher option, you should
 72        be able to start jEdit by clicking on any of the icons that the
 73        installation program provides. On other systems, you can enter
 74        <userinput>jedit</userinput> in a terminal window or create your own
 75        desktop or menu shortcut.

 80	<question id="java-web-start">
 81		<para>
 82			Why is there no Java Web Start version of jEdit?
 83		</para>
 84	</question>
 85	<answer>
 86		<para>
 87			In Java Web Start, dynamically-loaded classes (ie, plugins) run in a sandbox
 88			unless they are explicitly signed. Also, the protocol handler API prevents
 89			protocol handlers from being added if they are not loaded via the system
 90			class loader (i.e via the Java Web Start class loader). So the lack of plugin
 91			support and jeditresource protocol makes it useless.

207        </itemizedlist>
208        The package is a recommended option that is selected by default when you
209        install jEdit. The Java installer application launches a separate
210        Windows installer module for the native Windows executables that
211        comprise the jEditLauncher package. If the installation involves an
212        upgrade, you may be asked to reboot your computer to complete the process.

221        Regardless of the version of Windows that you use, if you have kept it
222        reasonably up-to-date with service packs or component upgrades from
223        Microsoft, you should have no trouble running jEditLauncher.
224        Users of Windows 98, Windows ME, Windows NT (version 4.0),
225        Windows 2000 and Windows XP have not reported problems involving missing

246                The latest version of jEdit, version 4.1, requires at least
247                version 1.3 of the Java 2 platform, and therefore will not
