hibernate - JPA Query: java.lang.ClassCastException: [Enum] cannot be cast to java.lang.Enum -


i need help...

i building application , using jpa queries there wrong enum types.

i have this.

public enum schedulingstatus {  skipped, pending_confirmation, confirmed, sent, processing, cancelled, finished, finished_with_errors, not_confirmed_in_server  }

then class farmirrigationscheduling.java many other fields , important one:

@column @enumerated(enumtype.ordinal) private schedulingstatus status;

and trying query:

typedquery<farmirrigationscheduling> query = getentitymanager().createquery(             "from farmirrigationscheduling farm = :farm , status not in :statuscollection order calculated desc",             farmirrigationscheduling.class);     query.setparameter("farm", farm);      schedulingstatus[] status = new schedulingstatus[] { schedulingstatus.finished,             schedulingstatus.finished_with_errors, schedulingstatus.cancelled };     query.setparameter("statuscollection", status);      return getsingleresult(query);

i getting following exception:

i don't why cannot cast enum java.lang.enum. before using hibernate , hql , working, changed having issue.

does know why , how can fix it??

thanks lot in advance!!

this has nothing enums.

you must pass in list, not array:

// create list: list<schedulingstatus> statuses = arrays.aslist(schedulingstatus.finished,         schedulingstatus.finished_with_errors, schedulingstatus.cancelled);  query.setparameter("statuscollection", statuses);
