Ptolemy II 2.0.1 Applets
Ptolemy II is available in several formats.This page covers accessing Ptolemy II via applets.
Other formats include:
You can browse Ptolemy II and run demonstration applets without downloading the distribution by accessing the web copy.
The web copy is merely a set of web pages that were created when we untar'd the distribution on the Ptolemy web site. Note that the 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
Note that to access the web copy applets you need a reasonably high
speed internet connection, DSL or better, or you will wait quite a bit
for applet downloads.
Note that the applet demonstrations work best with Windows, and that
you will need to have the Java 1.3 or 1.4 plug-in from
JavaSoft
installed. If you do not have the plug-in installed, you can still browse
the distribution and look at the source code and documentation.
To run the applets applets in a web browser, you will need the
Java 1.3 or 1.4 plug-in.
If you Java installed on your machine, then the plug-in may
already be available. To find out, try running the applets.
You may obtain the plug-in from
http://java.sun.com/products/plugin/
The plug-in is easiest to use from a Windows machine.
One way to determine what version of Java (if any) is installed is to run our Java Version Applet , which uses the Java 1.3 plug-in. Another way is to run the command below to see whether you have Java installed, and whether it is the proper version:
java -versionIf the command cannot be found, or the version that is printed is less than 1.3, you should install the plug-in, JRE 1.3, or JDK 1.3
When you visit a Ptolemy II applet, the first applet that is run
will download ptsupport.jar, which is 1.25Mb. Each applet
then will download smaller domain specific jar files of between 18k
and 65k. If you have a slow network connection, or if there is
congestion in the network or on our server, you may experience
significant delays before the first applet runs.
Some of the applets use Diva, a visualization package. The
diva.jar file is roughly 977k.

these demos. You can send email to
