I understand the basic concepts. Data organisation for this project is trivial. 

Houses->Rooms->Chairs

No I can't.... hence OP :)

The actual display tree component is irrelavent at this stage. Take for example my \
model....

House class has a @OneToMany List<Room> rooms in it.

Room has a House house parent reference in it.

hibernate deploys this and generates the tables, with constraints, as i would expect. \
My first step would be to, for example,  show the list of houses with the number of \
rooms in each. I've seen the boilerplate generated code for displaying normal \
properties, E.g. #{house.name} but how do i go about displaying house.rooms.size() in \
JSF/facelet. does any code for this need to go in a session bean? what alterations go \
in the entity. 

as i said i'm a beginner. a simple as possible please. 

many thanks

Ro
