Please include the code of your main.MyEventListener class. Are you implementing the ActivitiEventListener interface?

Best regards,

<code>
package main;

import org.activiti.engine.delegate.event.ActivitiEvent;
import org.activiti.engine.delegate.event.ActivitiEventListener;

public class MyEventListener implements ActivitiEventListener {

@Override
public void onEvent(ActivitiEvent event) {

    switch (event.getType()) {

      case JOB_EXECUTION_SUCCESS:
        System.out.println("A job well done!");
        break;

      case JOB_EXECUTION_FAILURE:
        System.out.println("A job has failed…");
        break;

      default:
        System.out.println("Event received: " + event.getType());
    }
}

@Override
public boolean isFailOnException() {
    // The logic in the onEvent method of this listener is not critical, exceptions
    // can be ignored if logging fails…
    return false;
}
}

I have also tried with following scenarios
First case:
[1] download tomcat 6 and install it
[2] download activiti 5.15.1
[3] extract activiti war in webapps folder of tomcat and copy all activiti/lib/*.jar to tomcat/lib
[4] created a jar <code>myEventJar</code> containing MyEventListener.class (i have attached my jar)
[5] change the activiti-explorer war to change activiti-standalone-context.xml (i have attached my xml)
[6] put myEventjar in lib folder of tomcat.
[7] start the tomcat
>>>> i see above error.
___________________________

Second case:
Extact same as first case + add all the latest spring jars to lib folder of tomcat
>>> same error.
___________________________
i am running it on window 7 with oracle java 6

Hi.. I was able to resolve the issue, the problem was:
[1] I had to turn on the unpackwar property true in server.xml
<code><Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"></code>
[2] The event listener need to be inside exploded war.

Tomcat unpacks the WAR by default, so don't understand why a specific configuration would be needed.
Yes, your JAR file needs to be part of the WEB-INF/lib folder of the Explorer and REST application.
