Red Hat versions 6.2 and 7.1 are officially supported by the Java Virtual Machine (JVM) included on your course CD. Other versions will work but are not thoroughly tested or documented.

The first five steps below tell you how to install the JVM on your computer.

1. Move the file j2re-1_4_0_01-linux-1586.bin from the course CD to the folder /usr/java/ on your computer. (If the folder does not already exist, you can create it.)
    
2. Open the Terminal Emulation Program.
    
3. Change directories to /usr/java/.
    
4. type:
   

   chmod a+x j2re-1_4_0_01-linux-1586.bin

   and then:

   ./j2re-1_4_0_01-linux-1586.bin

5. The JVM will install in the current directory.
    
6. Move the file Jython-21.class to /usr/java/.
    
7. type:
   

   java Jython-21

8. The Jython install wizard will launch.
