jax rs - Not null object but empty json -

i have jax-rs method returns me list do's. unfortunetly when go path mapped method empty json list like:

[{}, {}, {}] 

my resource method looks this:

@get @produces("application/json") public list<modeldo> getmodels() {     list<modeldo> models = modelrepo.findallmodelswithname("name");     return models; }  

i'm 100% sure objects exists , list isn't empty, because have checked in debugger.

the modeldo class simple pojo:

public class modeldo {     private int id;     private string name;      //public getters } 

what should non empty json response? ps. when i'm returning single object same problem -> {}

edit:

modelrepo:

public list<modeldo> findallmodelswithname(string name){     return new jpaqueryfactory(entitymanager).selectfrom(modelentity)                                        .where(modelentity.name.eq(name))                                        .fetch(); } 

modelrepo.class @injected resoure class

the reason model object did not have field setters, getters.
