Answer 1

Despite the question was last answered about year ago, perhaps the answer appears helpful to someone. Overall outlined by you architecture is fine, the only detail to add is: usually for passing data between layers (e.g. View and Service) instead of mentioned above UiBean-s so called DTOs (Data Transfer Objects) are used, these are plain POJOs with appropriate fields/setters/getters.

In one of previous/early versions of Java EE spec "DTO" term was mistakenly mixed with "ValueObject", though they have bit different purposes.

Hope, this helps.
