[Ace-users] Re: [ciao-users] Calling ccm_activate on CIAO 0.5.9

[Gan Deng]

Santos,

Could you please try this?

::Components::EnterpriseComponent_var new_client =
     home_client->create();
::Components::SessionComponent_var session_comp =
     ::Components::SessionComponent::_narrow(new_client.in ());
session_comp->ccm_activate();

Let me know whether it works for you.

thanks,
Gan
