[jacorb-developer] Why some operations use GIOP 1.0 instead of 1.2 ?

[Steve Osselton]

Try setting the GIOP version in the corbaloc you are using for the name
service (it defaults to 1.0)
this is why the ORB is using 1.0, when it resolves your service from the
name space it uses a full IOR
which will have the correct IIOP version (1.2) encoded.

corbaloc::1.2 at localhost:11000/StandardNS/NameServer-POA/_root

Cheers Steve.
