<hr SIZE=4 WIDTH="100%">
<br>The following table gives links to several demonstration JCSP Applets.
They illustrate a variety of animation effects and GUI controls.
All make significant use of JCSP concurrency to support the GUI, the application-specific
computation and the animation. The first group are slightly simpler
than the second. All sources are in sub-folders of this (jcsp-demos)
folder.
<p>The left column links will run the applets using <a href="http://java.sun.com/products/plugin/1.1.3/index-1.1.3.html">Sun's
Java PlugIn</a> (but please <i><a href="#warning">read the warning</a></i>
below). The right column runs the same applets using the native JVM
supplied by your browser - this needs to be compatible at least with JDK1.1.5
(e.g. Netscape 4.6, IE 5).

<p>All these applets may be run as applications - change to the <b><tt>xxx</tt></b>
source folder, where <b><tt>xxx</tt></b> is one of the above applet names,
and run the command: <b><tt>java</tt> <tt>xxxMain</tt></b>. For some
reason, applications sometimes run more smoothly than their equivalent
applets. Also, for some reason, all the animations (i.e. Balls, Infect,
Mandelbrot, Bounce, Plasma and Splat) run much faster and more responsively
under JDK1.1.x (where x >= 5) than under JDK1.2 (or JDK1.3/4) - see below.
<h3>
<a NAME="warning"></a>Warning - Don't Use the Plug-In Configured to Use
the JDK1.2 (or 1.3/4) Runtime Environment!</h3>
Most of these applets make moderate to heavy use of animation. Currently,
animations do not seem to be one of the strong features of JDK1.2 (nor JDK1.3/4) - they
seem very slow compared with JDK1.1.
<p>Our current recommendation is to download the <a href="http://java.sun.com/products/plugin/1.1.3/index-1.1.3.html">PlugIn
version 1.1.3</a>, which installs the JRE1.1.8. If you already have
the PlugIn version 1.2 (or above), it is recommended to configure it to
use a JDK1.1.x run-time environment (where x >= 5). This can be done
by firing up the "Java PlugIn Control Panel", clicking on the "Advanced"
tab, selecting a 1.1 "Java Run Time Environment" (which must have been
previously installed - e.g. by downoloading and installing the <a href="http://java.sun.com/products/plugin/1.1.3/index-1.1.3.html">PlugIn
version 1.1.3</a>) and clicking the "Apply" button.
<p><b><i>Note:</i></b> the native JVMs provided by Netscape 4.6 and IE
5.0 support a JRE1.1 sufficiently high to run these applet demonstrations.
<p><b><i>Note:</i></b> sometimes, IE 5.0 throws an application error when
trying to start an applet configured to use Sun's PlugIn .
<p><b><i>Note:</i></b> Sun's PlugIn 1.3 throws a <tt>java.security.AccessControlException</tt>
when the applet thread tries to construct a new thread. Investigating
...
version 1.1.3</a>, (left column) or the native browser JVM (right column
above).
<p><i><b>Note:</b> </i>we should provide JCSP support for Swing and this is in hand
(though in a slightly different way to the JCSP support for AWT).
