This Package

"index" - this file
source - the Java source necessary to create Sim.jar. First do "javac *.java" and then "jar -cvf Sim.jar *.class". The resulting Sim.jar file is then used for standalone Java simulations, or for Processing, it needs to be copied to the sketch "code" folders.
processing - a collection of programs written in Processing, to provide an audiovisual introduction to simulation. The index.html file provides a quick link to the sketch applets.
models - a collection of models from the book "Simulation Model Design and Execution" (P. Fishwick, 1995), written in Java. To use any of these models use the Sim.jar file from the source directory, then "jar -xvf Sim.jar" to get the classes and then compile the file(s): "javac *.java". Running a model can be done using "java model" where 'model' is the name of the corresponding class file.

Software for Computer Simulation Experiments

BROWSER:
We recommend that you use Mozilla Firefox for running Processing. Internet Explorer may work fine also, but the beta version of IE Version 7 has issues.
JAVA:
Java SDK. Before doing anything else, I recommend that you remove all existing java implementations on your system and install the latest Java. Technically, the Processing environment is supposedly checked for Java 1.4 but Java 1.5 seems to work fine. Simpackj has been tested with 1.5 and exhibits no issues. The SDK is preferred over the JRE, as this could be useful for certain types of Java code that you may be writing. The SDK includes a JRE inside of it, so you get everything.
SIMPACK:
SimPack (copy the most recent one) and Documentation. This file contains the main Java version of simpack (simpackj). Copy the directories simpackj/simpackproc and simpackj/libraries to your ..MyDocuments\Processing directory (for Windows). This will allow you to play the examples from the Processing Integrated Development Environment (IDE). To run Processing, just click on the icon in the Processing directory. If you are interested in running standalone code or rebuilding simpackj, read the simpackj\source\readme.txt file first.
PROCESSING:
Processing. Enter your email address and instructions for downloading will be issued through email. You should use the latest stable version. You will be asked to create Processing-based files for your homework or project. To do this, you can "Export" from Processing, and this will create a new "applet" directory, and a ".jar" file for your sketch. FYI: You can run this generated jar from the command line. For example, if your sketch is named "mysketch", and you export this sketch, then underneath the applet directory for this sketch, execute "java -cp mysketch.jar mysketch mysketch". When working with Processing and Java, pay special attention to file names. Java and Processing are case sensitive, so make sure that all file names inside code are spelled out exactly as they appear on the disk.
JSYN:
Jsyn. Press "Install Jsyn Plugin". If this does not work, they will suggest that you manually install it. For more detailed sound/audio work on the final project, download the SDK. To run any Processing program using Jsyn, you must place the ".jar" files from the Jsyn in a directory called "code" inside of your Processing sketch. See the Jsyn examples in the processing directory as to how to do this. FYI: The Jsyn .jar and .dll files should be placed underneath your Processing sketch's "code" folder, and all files (such as sample files) should be placed under "data". Samples must be monaural. If you have a stereo .wav file, convert it to mono with an audio editor such as GoldWave.
JET:
The following is purely optional. To create native code .exe files (Windows) of any Java or Processing codes, download and install Jet. Most Processing applets appear to be as fast as what you can do with this compiler, however, the compiler does produce .exe files which can be useful. Here is how to create an exe file: (1) Export your sketch from Processing; (2) Go to the applet directory, and preferably copy this directory to another location; (3) From this new location, execute "jar -xvf mysketch.jar" where "mysketch" is assumed to be the name of the sketch; (4) run "jc mysketch"; (5) this creates a "mysketch.exe".
