According to EJB Spec, Session beans are non-reentrant i.e. one instance can only service one client at a time. This should be true for all EJB containers, including JBoss.


Quoting the 2.0 spec:
anonymous wrote : Non-reentrant instances
  | The container must ensure that only one thread can be executing an instance at any time. If a client
  | request arrives for an instance while the instance is executing another request, the container may throw
  | the java.rmi.RemoteException to the second request if the client is a remote client, or the
  | javax.ejb.EJBException if the client is a local client.[6]
  | Note that a session object is intended to support only a single client. Therefore, it would be an
  | application error if two clients attempted to invoke the same session object.
