Regarding the Remote 3.0 lookup using the corbaname syntax, this looks
like a bug in our implementation which we'll fix. It's filed as :
https://glassfish.dev.java.net/issues/show_bug.cgi?id=735
There's a workaround listed in the bug report involving the use of a
adapted 2.x Home view. Let me know if you need any more info on getting
that to work. Thanks.
