Get user logged from request

[Diego Creador]

Hello Friends!

I dont know if this is the right topic to make this question. I need some advice, I have a web application and I need to get the user that is login.

This web application is built in java using JSF, and I need to get the user in the bean class. I know that I can get the user from the request parameter, the thing is that I have no idea how to get it? Can you give me some advice?

Thanks in advance.
Regards
Diego
