MVC pattern doubt

If I have an website with MVC pattern, and I have the servlet, JSP, and Bean.

In this scenario, if two users log in at the same time and the some state is store in bean then wouldn't there be a conflict or will each user have its own bean where some state/data could be kept for a while.

If there is a conflict then why should we use MVC pattern.

A servlet is a multi threaded object.
Each request is handled within it's own thread.
As long as you instanciate your bean from within one of the service methods there will be no concurrency issues.

Which all has little to nothing to do with MVC.
