I have one problem
Previously i was working on java Web server in 1999
Recently i tried to work with the same software.
But perhaps it has expired.
i tried to download the software from java.sun.com
but i do not find any one suitable.
on the advice of some person,
i download tomcat webserver software
but it has some problem.
It has following error message

JAVA_HOME environment variables are not defined
out of environment space.

I have installed jdk in c:\jdk directory

My problem is : can anyone suggest me where to
define the JAVA_HOME Variable.

i am very much confused
i tried on the autoexec.bat
by putting
set JAVA_HOME =C:\JDK\BIN but it did not work
