You have to do a bit of work to enable this -- we didn't end up  
including all the pieces in geronimo.

If you check out 
plugins/global-jndi you'll find a class EjbBindings.  I don't think  
this made it into geronimo itself.  If you build this little project  
and deploy an instance of this ejbBindings gbean in your ejb app it  
should result in each ejb getting bound in the global java:context  
under the names you specified in the openejb-jar plan.

I think the gbean config would look something like

<gbean name="EjbBindings"  
     <attribute name="homeContext">remote</attribute>
     <attribute name="localHomeContext">local</attribute>

Then a typical remote home would be bound at java:remote/foo.

Hope this helps and sorry for not making it easier.
