Hi @Florent ,
Hope you're doing well! Its nice talking with you after a long time. 😊
I came across your reply to this. I am also working on similar kind of requirement, so I tried this approach; however, I am getting a NullPointerException.
I tried debugging, but couldn't get any clue. Can you please suggest where I am going wrong? Here is my snippet.
public class AddQueueEntry {
/**
* @param args
* @throws WTException
*/
@SuppressWarnings("rawtypes")
public static void main(final String[] args) throws WTException {
final String TRADE_AUTOMATION_SYNC_QUEUE = "SomeCustomScheduleQueueName";
final String targetClass = AddQueueEntry.class.getName();
final String targetMethod = "processEntries";
final WTPrincipal principal = SessionHelper.getPrincipal();
/* This is how to declare HashMap */
final HashMap<String, String> keyValuePair = new HashMap<String, String>();
/*Adding elements to HashMap*/
keyValuePair.put("123456", "Value_1");
keyValuePair.put("456789", "Value_2");
keyValuePair.put("789123", "Value_3");
keyValuePair.put("753951", "Value_4");
final Class[] classArgs = new Class[1];
classArgs[0] = HashMap.class;
final Object[] objArgs = new Object[1];
objArgs[0] = keyValuePair;
final Calendar cal = Calendar.getInstance(SessionHelper.manager.getLocale());
cal.add(Calendar.MINUTE, 1);
final Timestamp startTime = new Timestamp(cal.getTimeInMillis());
ScheduleQueue scheduleQueue = null;
ScheduleQueueEntry scheduleQueueEntry = null;
try {
scheduleQueue = (ScheduleQueue) QueueHelper.manager.getQueue(TRADE_AUTOMATION_SYNC_QUEUE, ScheduleQueue.class);
System.out.println("*** scheduleQueue >> " + scheduleQueue.getName());
System.out.println("*** Session User >> " + principal);
System.out.println("*** Target Class >> " + targetClass);
System.out.println("*** Target Method >> " + targetMethod);
System.out.println("*** classArgs >> " + classArgs[0]);
System.out.println("*** objArgs >> " + objArgs[0]);
System.out.println("*** startTime >> " + startTime);
// Add an entry to queue
scheduleQueueEntry = scheduleQueue.addEntry(principal, targetMethod, targetClass, classArgs, objArgs, startTime);
System.out.println("*** Entry got added with number >> " + scheduleQueueEntry.getName());
} catch (final WTException e1) {
e1.printStackTrace();
}
}
public static void processEntries(final HashMap<String, String> keyValuePair) {
System.out.println("*** Total Objects Found :: " + keyValuePair.size());
final Set<Entry<String, String>> set = keyValuePair.entrySet();
final Iterator<Entry<String, String>> iterator = set.iterator();
while(iterator.hasNext()) {
final Entry<String, String> mentry = iterator.next();
System.out.print("key is >> " + mentry.getKey() + " & Value is >> " + mentry.getValue());
}
}
}
And here is error:
Thanks,

@ShirishMorkhade I got this working.
Per my earlier post I had been scheduling using batch file and Windows Task Scheduler. That works fine but wanted to see if I could schedule in Windchill.
Initially I was getting the exact error you were getting, Null Pointer at 270 in ScheduleQueue.java.
I decompiled the class to see what what going on under the hood. Everything looked fine.
BTW line 270 is
I then wrote my own class based on the what I saw in ScheduleQueue.class.
I ran my class and the error said no active wt.method.MethodServerException: No active method context.
Once I saw that I knew I had the solution. I needed a RemoteMethodServer. Aha!
I re-ran my original code in a RemoteMethodSever and it workeds.
And yes, I an using the same addEntry() method you are using.
See image below.
I did create my own queue but that's probably not necessary.
Also, as @Florent mentioned to get it to reschedule just call the method doing the scheduling at the end of the method you specify in the addEntry() method.
In my test I just have the method append some text to a log file. I reschedule to run in one minute. It works!
Hope this helps,
David
