java - In google-app-engine: How to query all entries after specific date in GQL -

i'm trying run simple query java application:

select * schedule date > datetime(2013,11,10) 

if following error json response:

03-06 14:03:13.730: w/system.err(13272): com.google.api.client.googleapis.json.googlejsonresponseexception: 503 service unavailable 03-06 14:03:13.730: w/system.err(13272): { 03-06 14:03:13.730: w/system.err(13272):   "code" : 503, 03-06 14:03:13.730: w/system.err(13272):   "errors" : [ { 03-06 14:03:13.730: w/system.err(13272):     "domain" : "global", 03-06 14:03:13.730: w/system.err(13272):     "message" : "javax.persistence.persistenceexception: problem query <select schedule schedule date > datetime(2013,11,10)>: unsupported method <datetime> while parsing expression: invokeexpression{static.datetime(literal{2013}, literal{11}, literal{10})}", 03-06 14:03:13.730: w/system.err(13272):     "reason" : "backenderror" 03-06 14:03:13.730: w/system.err(13272):   } ], 03-06 14:03:13.730: w/system.err(13272):   "message" : "javax.persistence.persistenceexception: problem query <select schedule schedule date > datetime(2013,11,10)>: unsupported method <datetime> while parsing expression: invokeexpression{static.datetime(literal{2013}, literal{11}, literal{10})}" 03-06 14:03:13.730: w/system.err(13272): } 

this exact query works fine when run admin console on app engine website 'date' datetime field , have index it. on app engine website field looks this: "2014-04-13 00:00:00"

here code:

    entitymanager mgr = null;     cursor cursor = null;     list<schedule> execute = null;      try {         mgr = getentitymanager();         query query = mgr.createquery("select schedule schedule "                                     + "where date > datetime(2013,11,10)");         if (cursorstring != null && cursorstring != "") {             cursor = cursor.fromwebsafestring(cursorstring);             query.sethint(jpacursorhelper.cursor_hint, cursor);         }          if (limit != null) {             query.setfirstresult(0);             query.setmaxresults(limit);         }          execute = (list<schedule>) query.getresultlist();         cursor = jpacursorhelper.getcursor(execute);         if (cursor != null)             cursorstring = cursor.towebsafestring();          // tight loop fetching entities datastore , accomodate         // lazy fetch.         (schedule obj : execute)             ;     } {         mgr.close();     }      return collectionresponse.<schedule> builder().setitems(execute)             .setnextpagetoken(cursorstring).build(); 

any me appreciated
