Subject Re: CORBA and GSSUP fix -- please review

Sorry, you're crediting me with a lot more CORBA knowledge than I
deserve.  :)  In particular, I'm not sure what the right IIOP URL or
corbaname URL should be.  Let me give you a more specific scenario:

Let's say I have a session bean running in Geronimo, so the Geronimo
side of the picture looks like this:

CORBA naming service: localhost:1050 (or
corbaloc::localhost:1050/NameService), with SSL enabled
EJB name in naming service: MySessionBean
EJB TSS listening for SSL on localhost:1055

Now I have a web app deployed in WebLogic with an ejb-ref in web.xml
pointing to the correct home and remote interface for this session
bean, but with no EJB link.  So I'm assuming I need to put something
in weblogic.xml in order to resolve this ejb-ref to point to the CORBA
EJB above.  What does that configuration block look like?

Also, if security is enabled for that session bean in Geronimo, so I
want to pass my username and password that I used for the WebLogic web
app across to the Geronimo EJB using GSSUP, and Geronimo requires that
the GSSUP token contain the domain name (or target name) of
"geronimo-properties-realm" along with the username and password, how
would I set that up in weblogic.xml?

Finally, let's say the EJB is running in WebLogic and the web app
running in Geronimo:

 - What naming service corbaloc would I use on the Geronimo side to
point to WebLogic's naming service?  Would it be

 - What is the name of the EJB inside the WebLogic naming service? 
e.g. is it one of the ejb-name or the jndi-name for that EJB, or is
there some other setting for it?

 - Is it OK to specify that SSL should be used to contact the naming
service and/or the EJB?  Does anything need to be done on the WebLogic
side to enable that?  (Other than I guess any URLs would go over the
SSL listen port not the regular WebLogic listen port.)

 - If the EJB is secured on the WebLogic side and I want to pass my
Geronimo login username and password to WebLogic via GSSUP, does
WebLogic expect any particular target name or domain name to come with
the username/password in the GSSUP authentication token?
