Quick Start Instructions
Ptolemy II is available in several formats:
You can browse Ptolemy II and run demonstration applets

The web copy is merely a set of web pages that were created when we untar'd the distribution on the Ptolemy web site.
To access Ptolemy II via the applets, you can either go directly to the web copy, or go to the Ptolemy II 2.0.1 Applets page for more information.
- Web Start
Web Start is a tool from Sun that
makes installation and updates particularly simple.
The Web Start installation works best with Windows, but has also been tried under Solaris, Linux and Mac OSX (!).
The Web Start installation does not include source, but behaves almost exactly like a standalone installation: you can save models locally, and you need not be connected to the net after the initial installation.
Note that the Applet web copy and the Web Start installations are different, the web copy is a set of web pages where some of the pages contain applets, and Web Start is a set of jar files that get downloaded to your machine so that you can run Ptolemy II at a later time, even if you are not connected to the network. For details, see the Installation Summary
To download using Web Start, see the Ptolemy II 2.0.1 Web Start page.
