You can reuse your object model, but not your classes. What your factories
are doing will be replaced by funtianlity finder methods in ejbHome objects.

> We are on that moment creating the "main" of the system, defining the

> Question? Besides defining the classes we are also making the

> that is to say defining "FACTORYs" that creates objects of
> those classes
> close to a database query.

> Example:
> Class Person{
> String name;
> int age;
>
> public Person(String name, int age){
> this.name = name;
> this.age = age;

> public String getName(){ return this.name;}
> public int getAge(){ return this.age;}

> Class FactoryPeople{
> public static getPeopleAtName(String name){

> 'It makes the database qyery catching Person's Registration
> with the Name
> ' With ResultSet, it creates an object Person
> return new People(rs.getString("name"),rs.getInt("age"));

> If I acquire a Server of Applications, for example Oracle

> How would a simple example be to write that class and make it
