Execution of listeners does not capture values

Hello peoples!

I've been trying for a few days to run listeners in a process with no success. I've done enough research and nothing.

See my code below:

package br.simas.process.listener;

import org.activiti.engine.HistoryService;
import org.activiti.engine.ProcessEngine;
import org.activiti.engine.ProcessEngineConfiguration;
import org.activiti.engine.delegate.DelegateExecution;
import org.activiti.engine.delegate.ExecutionListener;

public class MyExecutionListener implements ExecutionListener {
   private static final long serialVersionUID = 1L;

   public void notify(DelegateExecution execution) throws Exception {
      // TODO Auto-generated method stub

      try {

         execution.setVariable("initiator", execution.getEngineServices()

               // debug information
         System.out.println("Id corrente: "
               + execution.getCurrentActivityId());
         System.out.println("A definição do processo é: "
               + execution.getProcessDefinitionId());
         System.out.println(" O id da instância é: "
               + execution.getProcessInstanceId());

      } catch (NullPointerException e) {
         System.out.println(" O problema é " + e.getMessage());

The problem is that it always returns NULL.

I'm new to Activiti and I'm still studying a lot, what I want is to just capture the user who started the process instance, write that value to a variable and then use listener tasks to do the assignment capturing this variable, both for itself and for Your immediate superior through a SQL query.

If you have a simpler way to capture this variable would be interesting.

Can someone help me?
