No. This will not work in a clustered environment. However, what Mark
suggested is the simplest approach and should hold good in a normal ( not
clustered) webapp. If you want to achieve this is a clustered environment,
you will have to maintain a table, possibly in a Database, of user-ids and
possibly session-ids, login time. Before you autenticate the user as a part
of the login, you should check for the existance of the user-id in the table
and then proceed. 
Ofcourse, this introduces other complexities like cleaning up your table on
shutdown, cleaning up expired session-ids from the table etc

Will this work, if the application is running in a cluster?

So, if i've understood, I have to create a login runnable 
servlet(1) with a synchronized 
HashMap and check it every few times?

Store their login names and IPs in a context-scope hashtable upon login and
remove them when their session expires.  I'm not sure if Tomcat/JBoss has
some kind of tracking mechanism that provides concurrent session info, but
the documentation should tell you this.
