Question

I want to know how to export JAVA_HOME from Windows in shell script. Path for JDK in Windows is C:\\Program Files\\Java\\jdk1.6.0_32\\bin\\java When I run shell program I got the following error:

Files\\Java\\jdk1.6.0_32: command not found

Answer 1

The path to your JDK = JAVA_HOME is C:\\Program Files\\Java\\jdk1.6.0_32 . You have to add %JAVA_HOME%\\bin to PATH.

These lines could be part of your shell script:

set JAVA_HOME=C:\Program Files\Java\jdk1.6.0_32
set PATH=%PATH%;%JAVA_HOME%\bin

Answer 2

Although you can set these variables from a script, on Windows the normal way is to set them machine-wide.

Right-click on your computer icon in explorer. Select "Properties", then "Advanced System Settings", then "Environment Variables".

Add a variable with the name JAVA_HOME and the value C:\\Program Files\\Java\\jdk1.6.0_32

Find the PATH variable and append ;%JAVA_HOME\\bin (including the semicolon) to it.
