It depends on the client. If the client is multithreaded, then the EJB can
invoke a callback object.
The client must be a server in order to export its callback object, right?
If it is an RMI server built the usual way, then it is multithreaded, and
callback invocations should work fine. But if the EJB is accessible via
IIOP and the client is a single-threaded CORBA server, then a callback
invocation will deadlock.
