Thanks,
Mehrab

Hi Mehrab,

Check two 2 junit tests
org.activiti.engine.test.bpmn.event.timer.StartTimerEventTest
com.edorasware.gear.core.engine.support.activiti.ActivitiSpringBeanELResolverTest

in activiti source

Hi Maritn,

Thanks for reply. I have configured timer event that will fire every 1 minute . But it is firing 2 times in 1 minutes.
Here is my configuration, java method and log. Please help me to solve this issue.

<process id="TimerAutoExec" isExecutable="true">
    <documentation>Timer Auto Exec</documentation>
    <startEvent id="start">
      <timerEventDefinition>
        <timeCycle>R/PT1M</timeCycle>
      </timerEventDefinition>
    </startEvent>
    <sequenceFlow id="flow_start" sourceRef="start" targetRef="retrieve_data"></sequenceFlow>
    <serviceTask id="retrieve_data" name="Retrieve New Data" activiti:class="com.epsilon.al.ml.manager.ActivitiDelegate"></serviceTask>
<endEvent id="endevent1" name="End"></endEvent>
</process>

public class ActivitiDelegate implements JavaDelegate {
private static final Logger logger = LoggerFactory.getLogger(ActivitiDelegate.class);
@Override
public void execute(DelegateExecution arg0) throws Exception {
logger.info("——————–> Enter into delegate execute method");
}
}

Hi Mehrab,

Could you create jUnit test for that?
