How to read JSON to a list of generic objects in java? -

i have data web service, i'm using jackson have same problem using gson, have no problem single objects when receive several objects list not easy me.

json received this:

{"country": [ {"code":"ad","nombre":"andorra","name":"andorra"}, {"code":"ae","nombre":"emiratos Árabes unidos","name":"united arab emirates"} ] } 

this list of own class countrywstype, have several classes , need way can list of type of them. i've tried parse list:

list<myclass> myobjects = mapper.readvalue(jsoninput, mapper.gettypefactory().constructcollectiontype(list.class, myclass.class)); 

also trying creating own list type:

    public class listwstype<t> implements list<t>{      private list<t> listainterna;      //implents methods     } 

but jsonmappingexception , have no more ideas of how it.

i hope can me.

as people ask here class trying parse json:

@xmlrootelement(name="country") @xmltype(proporder={"code", "nombre", "name"}) public class countrywstype {      /** código iso */     @xmlelement(name="code")     public string code;      /** nombre en español */     @xmlelement(name="nombre")     public string nombre;      /** nombre en inglés */     @xmlelement(name="name")     public string name;      /** constructor sin parámetros. no inicializa nada...      * está para que funcione el marshall/unmarshall.      */     public countrywstype() {} } 

also notice when put myclass means countrywstype class, sorry missunderstood.

may help:

//first convert input string json array jsonobject jsonobject = new jsonobject(countriesasjsonstring);  jsonarray jsonarray = jsnobject.getjsonarray("countries");  //then type list , parse using gson type listtype = new typetoken<list<myclass>>(){}.gettype(); list<myclass> countrieslist = new gson().fromjson(jsonarray, listtype); 

if saying json arrary elements can of different types, mapper not know type of class instantiate , need supply additional attribute in json indicate that, ugly approach specially if json external facing. if want explained in this post.
