Hi,

I've a CORBA server which allocates servants for exclusive use for a =
given client.  I'd like to bind the lifetime of the servant to that of =
the client which uses it.  I've done this before in Orbix with =
smart-proxies which call a finished() method on the servant when they =
are about to be destroyed, however this approach fails when a client =
crashes.  Orbix has a client-crashed hook which I use to clean up the =
servants the client had allocated before it crashed.

My question are: =20

a) How do you create smart proxies in omniORB.  The only mention I've =
found refers to a section in the user's manual which doesn't exist =
anymore.

b) How can I ask omniORB to notify me when a client crashes ... I would =
also need to know which client crashed so I can clean up its resources.

Thanks,

John Swan-Stone
