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 questions are: =20
=20
a) How do you create smart proxies in omniORB. The only info I've found =
refers to a section in the user's manual which doesn't have that =
information anymore (Section 8.2).
b) How can I ask omniORB to notify me when a client crashes ... I would =
also need a client identifier so I could look up the and release the =
resources that client was using.
Thanks,
John Swan-Stone
