This section deals with installing jEdit using the Java-based installation program, as well as installation issues that are specific to particular operating systems.
What is the easiest way to install jEdit?
First, make sure you have a working installation of
the Java platform. To run jEdit, you will a platform package
having a version number of at least 1.6. If you do not
have the Java platform, we recommend downloading the larger
“Software Development Kit” (SDK), instead of
the smaller “Java Runtime Environment” (JRE),
because you will need the tools supplied with the SDK if you
will be using Java for development. You will need to know
the path of the Java application launcher, which is called
Next, decide whether you want the current "stable"
version or the latest development version. As a general
rule, the stable version is a good choice for first-time
users. Download the Java installer for the version

single file with a name in the style
To run the installer, do whatever you normally do to run a Java jar archive. If this is your first time, follow these steps:
The installer will load and display a series of dialogs for selecting a few simple options, including the directory in which you wish jEdit installed. It will also tell you how much disk space you need for the main program and various installation options.
If this is your first download of jEdit, you should definitely install the set of macros that come with the application. Many of them are useful for all programmers, and even the ones you don't use can serve as models when you eventually begin writing your own macros.
The installation process is very short. If you are
installing the program on Windows and you select the
jEditLauncher option, you should be able to start jEdit by
clicking on any of the icons that the installation program
provides. On other systems, you can enter
Why is there no Java Web Start version of jEdit?
In Java Web Start, dynamically-loaded classes (ie, plugins) run in a sandbox unless they are explicitly signed. Also, the protocol handler API prevents protocol handlers from being added if they are not loaded via the system class loader (i.e via the Java Web Start class loader). So the lack of plugin support and jeditresource protocol makes it useless.
How do I upgrade from one release of jEdit to another?
Simply delete the existing jEdit directory and run the
installer (if any) to install the new version. Settings are
How do I install jEdit on MacOS 8 or MacOS 9? s

How do I uninstall jEdit for Mac OS?

Is there anything different about installing jEdit on Windows?
For the Microsoft Windows family of operating systems, jEdit provides an additional package of features called jEditLauncher. These features include:
The package is a recommended option that is selected by default when you install jEdit. The Java installer application launches a separate Windows installer module for the native Windows executables that comprise the jEditLauncher package. If the installation involves an upgrade, you may be asked to reboot your computer to complete the process.
Do I need any special Windows components to run jEditLauncher?
Regardless of the version of Windows that you use, if you have kept it reasonably up-to-date with service packs or component upgrades from Microsoft, you should have no trouble running jEditLauncher.
Can I run jEdit on Microsoft's virtual machine?
The latest version of jEdit requires at least version 1.6 of the Java 2 platform, and therefore may not be compatible with 3rd party virtual machines.
