Hi Liljana,

It looks like you’re missing a separator in your CLASSPATH variable. Try this:

set JYTHON_HOME=C:/jython2.5.1
set JDBC_HOME=C:/JDBC
set CLASSPATH=%JYTHON_HOME%/jython.jar
set CLASSPATH=%JDBC_HOME%/ojdbc14_2.jar;%CLASSPATH%

No quotes (not needed unless you have spaces in your path) and forward slashes.

Hope this helps.

Hi,

I am trying to connect Jython 2.5.1, by using Grinder 3.4 to Oracle XE 10.g database.

from java.sql import DriverManager
from net.grinder.script.Grinder import grinder
from net.grinder.script import Test
from oracle.jdbc.driver import OracleDriver

I set up the classpath like this:
set JYTHON_HOME=C:jython2.5.1
set JDBC_HOME=C:JDBC
set CLASSPATH=”%JYTHON_HOME%jython.jar”
set CLASSPATH=”%JDBC_HOME%ojdbc14_2.jar”;%CLASSPATH%

but it keeps throwing the error:
19.10.10 10:08:11 (process OFFICEVIENNA01-0): Error running worker process (: No module named oracle
from oracle.jdbc import OracleDriver

I’ve downloaded the driver from this page:
http://www.oracle.com/technetwork/database/enterprise-edition/jdbc-10201-088211.html
I’ve been stragling with this error already 2 days.

Can somobody tell where is the error. What do I do wrong?

Maybe suggest me a link or code example or any other code example with another driver and DB that would work.

Thanks

Thanks Sath.

Regarding mauricio cobo’s issue, I’m not sure why adding the oracle library into the classpath would inhibit the grinder–probably a dependency collision.

Regarding your issue, I’d check and make sure that your classpath is set correctly.

Hope this helps.

Hi Moore,

I was trying to start Grinder 3.4. I am able to launch the console using the command “java net.grinder.Console”, but not able to run the agents. I used the command “java net.grinder.Grinder” it throws an error “Exception in thread “main” java.lang.NoClassDefFoundError: net/grinder/Grinder”. Can you please help

You can use the GrinderStone Eclipse plugin. It allows to debug and create Grinder scripts in a fast way. You can check it out from

Hi Tal,

To simulate different users for the grinder, this faq post is probably helpful (even though it just pulls the username/pw from a file):
http://grinder.sourceforge.net/faq.html#N10532

In order to do it by pulling an XML file down and then parsing it, you just need to write the python to do so (instead of from a flat file like the FAQ does). Here’s a link that might help you do that:
http://diveintopython.org/xml_processing/

Disclaimer: I have not tested any of this code.
