Question

I have configured a form based log in in my JSF 2.0 Application on GlassFish 3 server, using a custom Realm. What is the simpliest way of getting information about a logged in user, i.e. the users name.

Is this possible? Or is the current session just associated with a security role? If so, is there some way of making this possible without changing the log in configuration?

Simply put, what I want is to display a simple message like:

Logged in as username

on my webpages.

Answer 1

The easiest way to get at the logged in user via EL (Expression Language) in JSF 2.0 would be:

#{request.remoteUser}

Tobbe’s answer would work well to get at the remote user from within a backing bean.
