Hi Sravan,

Thanks for posting the query. PFB information which might be helpful to get the email listener at run-time.

Create a function with paremeters LogAttribute and  ListenerAttribute and put this code, from your service activity call this function with param value  (Stack,ListenerName) . function will give you the listener name

String attrValue= "";
boolean isStack = false;
if(!(LogAttribute.equals("pegathread") || LogAttribute.equals("app") || LogAttribute.equals("stack") || LogAttribute.equals("userid")))
{
   attrValue = "Fail:LogAttribute is empty or invalid";
}
if(LogAttribute.equals("stack"))
{
  isStack = true;
  if(!(ListenerAttribute.equals("ListenerName") || ListenerAttribute.equals("EmailServer") || ListenerAttribute.equals("Sender")))
  {
       attrValue = "Fail:ListenerAttribute is empty or invalid";
  }
}
try
{
 Class listenerClass = Class.forName("com.pega.pegarules.priv.LogContext");
 if(listenerClass!=null)
         {

      Class methodArgs[] = {String.class};
      Object attr[] = {LogAttribute};
              java.lang.reflect.Method listenerMethod = listenerClass.getMethod("get",methodArgs);
      String attrStr = (String)listenerMethod.invoke(null,attr);
              if(isStack)
              {
                  int stackIndex = attrStr.indexOf('|');
  String listenerStack = attrStr.substring(0,stackIndex);
  String listenerArr[] = listenerStack.split("\\.");
                  if("ListenerName".equals(ListenerAttribute))
                  {
   attrValue = listenerArr[1];
                  }
               else
  {
           attrValue = listenerArr[2];

  } 
      }
              else
              {
                 attrValue = attrStr;
              }
        }
}
catch(Exception e)
{
  oLog.error("Exception while seeking GetEmailListenerName:"+e);
}
return attrValue;
