Answer 1

in your example, the DatastoreServiceFactory.getDatastoreService().getCurrentTransaction() argument is used to attach a task to the current datastore transaction. if you provide that argument, the task will be added if and only if the datastore transaction commits.

in your case, the task probably isn't executing your servlet because you don't commit the datastore transaction. remove the transaction parameter entirely and just try this instead:

queue.add(TaskOptions().url("/path/to/my/worker"));
