Hello,
I am reading data from mongo in Java, with this code:
DBObject dbo = new BasicDBObject(LOCKED_DOC_ID_FIELD, gdto.getDocId()); DBCursor lock = locks.find(dbo); if (lock.count() == 1) { DBObject lockDBO = lock.next(); long createdAtTS = (Long) lockDBO.get(CREATED_AT_FIELD); Date d = new Date(createdAtTS); return new Lock(gdto, d); } else if (lock.count() > 1) { throw new IllegalStateException("It seems like mongoDB locks.locks collection does not have a unique index on lockedId. Do: use locks; db.locks.ensureIndex({lockedDocId:1}, {unique:true})"); }
I somtimes get an Exception on `DBObject lockDBO = lock.next();`:
java.lang.RuntimeException: no more
at com.mongodb.DBApiLayer$Result.next(DBApiLayer.java:388)
at com.mongodb.DBApiLayer$Result.next(DBApiLayer.java:350)
at com.mongodb.DBCursor._next(DBCursor.java:421)
at com.mongodb.DBCursor.next(DBCursor.java:494)
How can this be?
Thanks for your precious help.
Brice.
