Answer 1

Did you mean like this?

    BasicDBObject obj = new BasicDBObject();
    obj.put("image", ....);
    for(Tag tag:tags){
        BasicDBObject tagsObj = new BasicDBObject();
        tagsObj.put("NNP",tag.getNNP());
        tagsObj.put("NN",tag.getNN());
        obj.put("tags",tagsObj);
    }
