Installing the Java Runtime does not require any expertise in Java programming. Mostly, it consists of running the installation program provided with the JVM and setting a few environment variables.

Sun Microsystems, Inc.'s official Java Runtime Environment (JRE) is highly recommended to run the CallSite. Sun Microsystem's JRE for Windows (x86) and Solaris (Sparc) are bundled with CallSite.
You can download the JRE at the URL: http://java.sun.com/j2se/
