targetNamespace in callbackHandler

[Ben Berner]

Hello cxf-users,
I need to check whether the client invoking a web service is authorized to
do so.  The database has targetNamespace of the service paired with the
username/key.  So, need to find the targetNamespace of the WebService at
runtime in ServerPasswordCallback Class that implements CallbackHandler
(using ws-security).  Is this possible via some api or I need to inject
something into this callback class?
Regards,
Ben
