Why doesn't this work?

for %x in (.\*.jar) do set CLASSPATH=%CLASSPATH%;%x

I do know in a bat file I'm supposed to have %%x. Bugging me. Is there any way to do this without having to call to an external bat file to set the classpath?

Ah the joys of DOS batch programming. As far as I can remember I think environment variables are only updated when the batch file exits, so your way will only store the last .jar file in CLASSPATH. If you want to do this without having to have 2 batch files, this should do the trick (make sure it's called 'setclass.bat'):

@echo off
if not "%1"=="" goto param
for %%x in (.\*.jar) do call setclass %%x
goto end
:param
set CLASSPATH=%CLASSPATH%;%1
:end

Hah - as you may have guessed, that line should read ':param'

I think this will work in NT/2000. Not going to bother changing though as I'm trying to be able to run it across different Win flavours.

@echo off
if not "%1"=="" goto param
for %%x in (.\*.jar) do call :param %%x
goto end

:param
set CLASSPATH=%CLASSPATH%;%1
goto end

:end
