the timers obtained in getTimers are only of current client or of all applications?

It returns the Timers associated with the bean. Please see this: http://docs.oracle.com/javaee/6/api/jav ... #getTimers()

but, if the bean is stateless, the timer "of bean" is only that client, of this unique call or the all clients? Considering that stateless bean not maintain state between calls, the container not ensure the same bean not serve multiples clients.

Timers are for a bean not for a client. So it will return all the timers. BTW, only a stateless or a singleton bean can use timers.
