hi there

i've searched high and low in the mailings list, the FAQ, the docs, and 
even in the wide web, yet i cannot make my parallel script work. im 
pulling my hair now, can someone help me?

here's my script, it's called parallel-run.py (and yes, it's based on 
the example from the grinder script gallery)

parallel-run.py
---------------
from net.grinder.script.Grinder import grinder

scripts = ["script1", "script2", "script3", "script4"]

# Ensure modules are initialised in the process thread.
for script in scripts: exec("import %s" % script)

def createTestRunner(script):
    exec("x = %s.TestRunner()" % script)
    return x

class TestRunner:
    def __init__(self):
        script = scripts[grinder.threadID % len(scripts)]
        self.testRunner = createTestRunner(script)

    # This method is called for every run.
    def __call__(self):
        self.testRunner()


grinder.properties
------------------
#
# Example grinder.properties
#

grinder.processes=1
grinder.threads=50
grinder.runs=5

grinder.useConsole=false
grinder.logDirectory=C:\grinder\logs
grinder.numberOfOldLogs=0

grinder.script=C:\grinder\projects\GED-i\parallel-run.py

script1=C:\grinder\projects\GED-i\gedi-W-localhost-p1.py
script2=C:\grinder\projects\GED-i\gedi-W-localhost-p2.py
script3=C:\grinder\projects\GED-i\gedi-W-localhost-p3.py
script4=C:\grinder\projects\GED-i\gedi-TT-localhost.py

#grinder.jvm.arguments=-ms300m -mx512m

startAgent.cmd
----------------
call setGrinderEnv.cmd
%JAVA_HOME%\bin\java -cp %CLASSPATH% net.grinder.Grinder %GRINDERPROPERTIES%

setGrinderEnv.cmd
-------------------
set GRINDERPATH=C:\grinder
set ENGINE=grinder-3.0-beta33
set JAVA_HOME=C:\java\j2sdk1.4.2_09
set GRINDERPROPERTIES=%GRINDERPATH%\etc\grinder.properties
set 
CLASSPATH=%GRINDERPATH%\engine\%ENGINE%\lib\grinder.jar;%GRINDERPATH%\engine\%ENGINE%\lib\jython.jar;

when i execute startAgent.cmd it i get this error message:
7/30/07 4:13:01 PM (agent): worker ELISEO-DELL-0 started

7/30/07 4:13:02 PM (process ELISEO-DELL-0): Error running worker process 
(Import
Error: no module named script1
        File "<string>", line 1, in ?
        File "C:\grinder\projects\GED-i\parallel-run.py", line 9, in ?)
7/30/07 4:13:02 PM (agent): finished

this is what i have tried so far, unsuccessfully:
1) removing the read-only attribute in C:\grinder\lib\cachedir & 
C:\grinder\engine\grinder-3.0-beta33\lib
2) removing the extension from the script filenames (e.g. 
script1=C:\grinder\projects\GED-i\gedi-W-localhost-p1)
3) using grinder.script with different filenames as mentioned here: 
http://www.nabble.com/Multiple-scripts-in-grinder.properties--tf196639.html#a548759
(e.g. grinder.script=C:\grinder\projects\GED-i\gedi-W-localhost-p1
grinder.script=C:\grinder\projects\GED-i\gedi-W-localhost-p2, and so on 
[tried with no extension and with .py])
4) removing the path from the script values, leaving just the name, 
after placing the scripts in C:\grinder\bin (e.g. 
script1=gedi-W-localhost-p1.py
script2=gedi-W-localhost-p2.py)

im using grinder 3 beta 33, jvm v1.4.2_09 on windows xp sp2. does anyone 
know what am i missing? any help will be appreciated, thanks
