Hi Olivier,
Whenever a system exception is thrown by any of the session
bean's business methods the bean instance is discarded. In the case of
stateless session beans each method call goes to an instance in the
pool. It need not be the same instance. So even if the instance is
discarded this is transparent to the bean developer.
In the case of a stateful session bean, all the calls go to the same
bean and so if the previous call threw a system exception then the
corressponding stateful session instance will be discarded and you
will get the javax.ejb.NoSuchEJBException.
Use the @javax.ejb.ApplicationException annotation to specify that an
exception class is an application exception.
Regards
Manu
