Hi everybody,
we were looking for a solurtion to this problem
We want to get a Proxy to a corba object:
CORBASCAG scag = (CORBASCAG)
Corba.narrow(Namespace.lookup("deriva/SCAG"), CORBASCAG.class);
which is previously asociated in a namespace:
Namespace.rebind("deriva/SCAG", new SCAG());
and obviously the class SCAG implements a CORBA interface:
public class SCAG implements CORBASCAG {
but we get this exception:
Internal Servlet Error:
javax.servlet.ServletException: deriva.system.SCAG@296683 is
not a proxy to a CORBA object

The technologies used by us are:
JSP provided by Tomcat 3.3-m4
our ORB is Voyager 3.1
it's indispensable to use Voyager (we implements movile agents), please,
don�t suggest using another ORB
Bye, Nacho & Eva
PD: Thank you.
