[Ace-users] Re: [ciao-users] saving and loading the state of a component

[Douglas C. Schmidt]

Hi Folks,

   Although LwCCM and CIAO don't support the persistent container policies
it should be possible to use TAO's Persistent State Service (PSS)
mechanisms to save/restore the state of components.  Please see the
examples of how to do this in TAO_ROOT/orbsvcs/examples/PSS.

   Thanks,

   Doug
