Running Windows XP batch on Windows 7

I have a batch file which runs on XP:

@echo off
@setlocal 
set CWD=%~dp0
set JYTHON_HOME=%CWD%
set LIB_DIR=%JYTHON_HOME%/lib
java -cp %LIB_DIR% -jar %LIB_DIR%/jython.jar -Djython.home=%CWD%
-Dpython.path=%LIB_DIR%;%CWD%/ext %LIB_DIR%clenotes/clenotes.py %* 
@endlocal

I want to run this file on Windows 7.

EDIT:

When I run it this error occurs:

Exception in thread "main" java.lang.NoClassDefFoundError:
folder\CLENotes\lib Caused by: java.lang.ClassNotFoundException:

Actually it is very simple, I needed to change the fowardslashes (/) to backslashes.
