Hi,
I am trying to create timer programatically.
But I am getting class cast exception when registring the action for timer.

CreateTimerAction cta = new CreateTimerAction();
 cta.setTimerName("myTimer");

 cta.setDueDate("1 minutes");
 cta.setTransitionName("myTransition" );

 Action action = null;
 String actionName = "MydActionHandler";
 Class actionType = ClassLoaderUtil.getClassLoader().loadClass(actionName);
 try {

 action = (org.jbpm.graph.def.Action) actionType.newInstance()
 cta.setTimerAction(action);
 } catch (Exception e) {
 log.error("error msgs = "+e.toString());

 }

the log is as follows

couldn't instantiate action 'com.TrialActions.SecondActionHandler', of type 'com.TrialActions.SecondActionHandler'
java.lang.ClassCastException
