Hi Shruthi,

My requirement is track the active users who logged into application. I followed the below PDN link to implement

https://community.pega.com/knowledgebase/articles/user-interface/tracking-online-presence-operators

Add the custom category to the Operator Presence channel.

1. Click Designer Studio > User Interface > Notification channels.
2. Click the Gear icon next to the Operator Presence channel.
3. Click Add category, and enter the category name.(By default it is standard)
4. Click Submit.

Configure your application component to subscribe to the channel.

1. Added the dynamic layout 
2. Select the layout, and click the Gear icon to open the layout properties panel.
3. Click Actions.
4. Click Create an action set.
5. Click Add an event, and select On load under Other events.
6. Under Subscribe, select Operator Presence from the Channel name list.
7. Select a category.
8. Select the source of the operators list

I selected Data Page as source and provided OOTB Datapage "D_OperatorsList". 

Click Add an action for callback to select the operation to be performed after receiving the updates. I selected the refresh section and i called one activity which calling the custom java code 

Custom Java code:

/* Below params are kept in param page and then fetch activity should be invoked */
oLog.info("Start");
List <String> operatorsList = (List <String>) tools.getParameterPage().getParameterValue("OperatorList");
oLog.info("OperatorList" +operatorsList);
List <PresenceQueryClause> clauses = new ArrayList <PresenceQueryClause> ();
String query = "A";

if (operatorsList != null) {
  oLog.info("Entered if Condition");
 PresenceQueryClause clause1= PresenceQueryClause.Builder.createEqualsClause('A', PresenceQueryClause.STANDARD_CATEGORY, PresenceStandardAttributes.STATE.getName(), "ACTIVE", false); 
 clauses.add(clause1);
   oLog.info("Clause1" +clause1);
}


try {
 List <PresenceRecord> results = tools.getPresenceService().queryPresence(query, clauses, PresenceQueryClause.STANDARD_CATEGORY);
   oLog.info("Results" +results);
 Map <String, PresenceRecord> fetchUsersResponseMap = new java.util.HashMap <String, PresenceRecord> ();
 for (PresenceRecord record: results) {
  fetchUsersResponseMap.put(record.getOperatorId(), record);
 }
 /* OperatorsPresenceMap params will be avaliable in param page */
 tools.putParamValue("OperatorsPresenceMap", fetchUsersResponseMap);
} catch (PresenceException e) {
 oLog.warnForced("QueryOnlinePresence: Exception occured", e);
}

But when i am running the above activity manually which is having the javacode. i am getting runtime exception. attaching the screen shots .

Could you please tell me if i am following correct or anything else i am missing.

Thanks for help in advance
