Create an environment variable named PLATFORM_HOME that points
to the SpringSource Application Platform installation directory.
Edit the .profile file in your home directory to
add the PLATFORM_HOME environment variable. For
example, if you installed into /opt:
export PLATFORM_HOME=/opt/springsource-ap-1.0.0.beta1/
From the Start menu, open the Control Panel and double-click on 'System Properties'.
Click the 'Advanced' tab and select 'Environment Variables'. Next, click the 'Edi't button in the 'System Variables' section.
This will display the 'Edit System Variable' window. Enter PLATFORM_HOME as the 'Variable name' and
the installation directory as the 'Variable value'. Click OK.
