Due to the complexity of having to specify yet another object (first remote i/f,
home i/f, Entity, and now a container for the fields) I would use something more
dynamic, like a HashTable or a Dictionary, to store the fields.
Nevertheless, I have not tried this solution, neither the next one yet.

What people is considering is having a session bean that construct a structured
document out of the bean, containng information and presentation logic, and
returns such a document to the client. The client then processes this document at
will.
