не могу понять как построена архитектура ajax + jsf в таких фраймворках как icefaces или seam. помогите разобраться с вызовами в архитектуре.. а именно.. представим, есть некая страница, которая реализует ajax + jsf, как пример: | Код |

<h1>Integrated multi-layer validation</h1>
<p>
Robust applications need data validation in several different places. Seam integrates Hibernate Validator,
a set of annotations for expressing data model constraints in your domain model classes. Then, these
constraints are applied almost completely transparently at three levels of the application: by Seam when
the user first enters data, by EJB before persisting data to the database, and, if you use Hibernate to
generate your database schema, by the database constraints themselves. Multi-layer validation hardens
your application and protects your data. Even better, it's self-documenting, and easy to change when
your business rules change.

при заполнении таких input полей как id="register:password" и переходе на следующее поле сработает onBlur() и данные будут посланы серверу.. например: | Код |
partial=true&ice.event.target=register%3Aname&ice.event.captured=register%3Aname&ice.event.type=onblur
®ister=&icefacesCssUpdates=&viewNumber=1&icefacesID=0j7A5cxlreaMtXw0tE_yrw®ister%3Ausername=polosatij
®ister%3Aname=®ister%3Apassword=®ister%3Averify=&focus_hidden_field=&focus=&icefacesID=0j7A5cxlreaMtXw0tE_yrw
%2C&viewNumber=1%2C&rand=0.0025119876651192863

и вот с этого момента я не понимаю.. во первых, кто получает эти данные? куда именно они передаются?  есть ещё один файл, исходя из #{user.password} => а именно класс User. здесь данные проверяются на валидность: | Код |

{
this.name = name;
this.password = password;
this.username = username;
}
public User() {}

public String getName()
{
return name;

this.name = name;

{
return password;
}

{
this.password = password;
}

не пойму.. а где промежуточное звено между ajax-ом и самой ява? как именно вызывается класс User и кто его вызывает? |
