As I said, there's nothing wrong with that. However, doing that implies that
the application doesn't respect the HATEOAS constraint, even if it has
"connectedness". And if it doesn't respect that constraint it's not a
Restfull application. And doesen't possess the characteristics that that
constraint allows, meaning scability via decoupling from client and server.
But of course there's nothing wrong with not being Restfull, as long as
people are aware of that and what that means.
Neverthless, I realise that this is the Jersey list, not the Rest list, so
there is no point in discussing this in here.
