Retrieving the logged in user from session context

[yannfromparis]

Hi all,

I'm struggling to figure out how to get the logged in user from the session context. I'm using seam identity management which relies on the UserAccount entity (created by seam-gen). Does the authentication mechanism store such an entity in the session context for the current user, or do I have to do something by myself like extending the Identity component to achieve this ?

Sorry if this is a newbie question but I'm quite new to Seam and web programming in general, so if someone could be kind enough to give me a clue...

Thanks,

Yann

To obtain the current user name:

if(Identity.instance().isLoggedIn())
      return Identity.instance().getPrincipal().getName();

Francisco, thanks for your reply. However, I've found in the seamspace source code just what I need. The trick is to use an Observer on the EVENTUSERAUTHENTICATED event, to put a reference in the session context.

Why do you reinvent the wheel? If Identity.instance() already allows you to retrieve the currently loggeding user I see not point it wasting memory by storing that information twice in the current session...

Sometimes you want the actual User entity (or at least the primary key), e.g. I have a system where the unique representation of a user is (domain_id, username) so just the username is not enough to know who is logged in.
