Hello guys,

Is there any good explanation or tutorial which describes the common way how can we create entity beans from the received data of the form ? The main reason of my question the treating the received ids (e.g id of country,city and so forth) which is the way from the id to entity ?

Example:

................Client side form 

username:String
countryid:Integer (could be a drop down)

................Server side entities

public class UserBean
{
  String username;
  CountryBean Country;
}


public class CountryBean
{
  String cityname;
  Integer id;
}

............................................

Maybe the question is dependent of the used technology, but I guess there is a very common way. I would like to comprehend the conventional approach of this problem. (For the sake of the completeness I would like to save the form data (received by Stripes) by JPA)

Thanks advance.
