Jython 2.5.x and 2.2.x
----------------------

Basic Install
=============

Jython 2.5.1 and 2.2.1 are distributed as executable jar file installers. After
`downloading <DownloadInstructions>`__ it, either double click the
|stable.installer.jar| or run java with the -jar option

.. parsed-literal::

    java -jar |stable.installer.jar|

This will start the regular GUI installer on most systems, or a
console installer on headless systems. To force the installer to
work in headless mode invoke the installer as:

.. parsed-literal::

  java -jar |stable.installer.jar| --console

The installer will then walk through a similar set of steps in
graphical or console mode: showing the license, selecting an install
directory and JVM and actually copying Jython to the filesystem.
After this completes, Jython is installed in the directory you
selected. Executing a script in the install directory, ``jython`` on Unix-like systems or ``jython.bat`` on Windows, will start up the Jython
console, which can be used to dynamically explore Jython and the Java
runtime, or to run Jython scripts.

Standalone mode
===============

The standalone option does no caching and so avoids the startup overhead (most likely at the cost of some speed in calling Java classes, but I have not profiled it)

You can try it out by running the installer:

.. parsed-literal::

    $ java -jar |stable.installer.jar|

then when you come to the "Installation type" page, select "Standalone".

The installation will generate a ``jython.jar`` with the Python standard library (``/Lib``) files included, which can be run as: ::

    $ java -jar jython.jar

Of course you can run scripts just by calling them as you might expect: ::

    $ java -jar jython.jar script.py

Or, add this file to the classpath of your application.

Installation options
====================

You can get a list of installer options (to install Jython unattended, for example) by running:

.. parsed-literal::
