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 CallSite applications.
You can download the JRE at the URL: http://java.sun.com/j2se/index.jsp

Installing the Sun JRE on Windows 95/98/NT/2000/XP/2003 systems

Save the JRE installer you downloaded in the 'callsite\jre_inst\' directory of the CallSite archive.
Simply run the .exe file and follow the instructions.

Then update your Windows environment variables or the AUTOEXEC.BAT file. If it is needed add the following lines :
SET PATH=%PATH%;%JRE_HOME%\BIN
SET CLASSPATH=.;%JRE_HOME%\LIB\rt.jar
(The variable %JRE_HOME% is the JRE installation directory; it should be C:\Program Files\Java\JRE\1.5 or C:\jdk1.5).

Installing the Sun JRE on UNIX Solaris systems

Save the JRE installer you downloaded in the 'callsite/jre_inst/' directory
Simply launch the .bin file and follow the instructions.

If you use the csh:
Add the following lines to your '.cshrc' file :
set path = ( $JRE_HOME/bin $path )
setenv CLASSPATH .:$JRE_HOME/lib/rt.jar
(The variable $JRE_HOME is the JRE installation directory)

If you use the sh:
Add the following lines to your '.profile' file :
PATH=$PATH:$JRE_HOME/bin; export PATH
CLASSPATH=.:$JRE_HOME/lib/rt.jar; export CLASSPATH
