How do I restrict the same user log-in on the same time ...

[khangfpt]

Hi all JBoss Portal 4rum members,
My customers want to restrict the same user cannot loged into portal on the same time in another PC (that mean - if that user has loged in portal, they can not use this username to log-in to portal from another PC).
I have made a look in portal APIs & Portlet development documents, but I can't find any interfaces to check user login status (such as isLoged() or something like that). How can I find another methods or interfaces tell me the users loged-in list or user status in JBoss Portal?

Thanks

try

 request.getPrincipal()

If the returned value is null, user is not logged in

If user is logged in you get the username of the user returned

Hi Sohil,
Thanks for your replying, but I think method getPrincipal() has scope only in this request, so it can not get user information from other request or request from other PC.
