making grinder work with jython

Question

I have a java class for starting the server on ActiveMQ and I want to hook up grinder with the JMS messaging, so I am writing a client code in jython with Grinder. When I run the server and try to send a message from my jython client, I get the following error:

  Tests resulting in error only contribute to the Errors column.          
  Statistics for individual tests can be found in the data file, including
  (possibly incomplete) statistics for erroneous tests. Composite tests   
  are marked with () and not included in the totals.                      

my client code is a below:

from net.grinder.script.Grinder import grinder
from net.grinder.script import Test


from com.droitfintech.core.jms.factory import JMSBuilderFactory

log=grinder.logger
test1=Test(1,"Log method")
test1.record(log)

class TestRunner:
    def _call_(self):
        log=grinder.logger.info
        log("Creating queue session")
        messageQueueName="InputQueue"

        fileName=open('basis_USD3s6s.xml','r+').read()


        print fileName    
        newInstance=JMSBuilderFactory.getInstance()
        newInstance.getConnector().sendMessage(messageQueueName,fileName)

Answer 1

rename your _call_ method to __call__
