Answer 1

You have to define your %JAVA_HOME% yourself, create the variable if it doesn't exist.

Answer 2

You need to set the JAVA_HOME variable in your Environment variables.

Be sure to set it to the root of your JDK folder.

e.g. C:\Program Files\Java\jdk1.6.0_16\

For some reasons my comments are not showing up. The command window does not pick up changes to the environment variables dynamically, be sure to open a new command window after you have made the change.

Answer 3

For windows:

REM Set to whatever JDK is installed to:
set JAVA_HOME="C:\Program Files\Java\jdk1.6.0_16\"

set PATH=%JAVA_HOME%/bin;%PATH%

REM this will give you trouble soon enough ;)
set CLASSPATH=.;%CLASSPATH%

Another option is to get an IDE like Eclipse or NetBeans. They will do most of it for you.

Answer 4

Define that in the environment variables.
