These are general instructions for installing the Java class files and using them. This file also is in the jar files. First, unjar the exe files (yes, the files have an 'exe' extension but are actually 'jar' files so a browser will ask you if you want to download the file instead of trying to execute it). This can be done using 'jar', which comes with Sun's Java 1.1.x or 2.x JDK, which can downloaded from http://www.javasoft.com. Using 'jar', the command line command to use would be 'jar -xvf filename', where 'filename' is the name of the file to unjar.
Included with each jar file are class files in two directories called javlarry and awtlarry. The contents of these directories are identical for each jar file. After extracting the class files, they may be transferred if they are to be used on another machine.
For browser access from a web server, the installed directory structure should be preserved. If both Java programs are to be used, they can be extracted into the same directory and accessed from there; this will allow them to share the class files in the javlarry and awtlarry directories. Of course, the programs may be placed in different directories, but the contents of the javlarry and awtlarry directories will be duplicated. The html files supplied can be used to load the applets.
To run the programs locally as applications, a Java runtime interpreter, such as Microsoft's JView or Sun's Java, is needed. The main Amortize class file is Amortize.class; the main backgammon class is CBgjavaApplet.class. For instance, the Java amortization program would be invoked on a Win32 platform by entering 'JView Amortize' on the command line in the directory containing Amortize.class. When executed locally, the class files in the javlarry and awtlarry directories may be placed anywhere in the CLASSPATH.
