private String ErrorMessage;   
private String ResultCode;
private List<KategoriItem> Payload;

 ..

Second KategoriItems

public class KategoriItem implements Serializable{
private int RowIdx;
private int Id;
private String Title;
private String Type;
private String WebUrl;
private List<ChildrenItem> Children;
private Boolean VideoItems;
 ..
 ..

 ..

and ChildrenItems

 public class ChildrenItem implements Serializable{
private int RowIdx;
private int Id;
private String Title;
private String Type;
private String WebUrl;
private Boolean Children;

Answer 1

java: private List ChildrenList;

json: Children : []

May be you should rename "ChildrenList" <-> "Children". What setter name do you use?
