Do you really mean to be looking for ejbs from exactly one ejb  
module?   If so, you should include the name of the module in this  
gbean's name.

I was thinking that there would be a standard name + wildcard that  
would include all EJB containers both present and future.   Will all  
EJB containers have a standard naming convention or will deployers be  
able to set their own name?    If user can set their own name then a  
standard name with wildcard may not be added to my collection.
The naming conventions for ejbs must be followed or nothing else will  
work either:-)

I think you want the same patterns as ContainerIndex uses:
        <references name="EJBContainers">
             
<pattern>geronimo.server:j2eeType=StatelessSessionBean,*</pattern>
             
<pattern>geronimo.server:j2eeType=StatefulSessionBean,*</pattern>
            <pattern>geronimo.server:j2eeType=EntityBean,*</pattern>
        </references>

You might be able to use *: or : but I wouldn't experiment too heavily  
:-)

Using openejb.server for the domain name would certainly prevent any  
ejb containers from being added to your collection :-)

       <reference  name="AdapterManager">interop:  
type=AdapterManager,name=AdapterManager</reference>
   </gbean>

I recommend that you move to the more-automatic gbean naming system   
where you specify the j2eeType in the GBeanInfoFactory constructor  
and  only the namePart in the xml config.  If you'd like me to modify  
your  gbeans for this I'd be happy to.
What would suggest the name be?
This all depends on how many gbean classes you have, how many instances  
of each class will get deployed, and what kind of relationship between  
them might occur.

If there is exactly one of a gbean, and it's part of the system  
configuration, you can leave the type as "GBean" (the default) or make  
it something more informative such as "CORBAResource".  I don't recall  
any jsr-77 standard type for corba-related components, but this is  
similar to the mandated JTAResource I'm using for the transaction  
manager.

If there are potentially lots of instances of a gbean (like  
EJBContainers) you should the particular gbean its own type such as  
"CORBAWidgetRegistry" (you can tell how much I know about corba).

After you decide on type names, you should add it as a constant to  
NameFactory and use it when constructing GBeanInfo like this:

        GBeanInfoBuilder infoFactory = new  
GBeanInfoBuilder(TransactionContextManager.class,  
NameFactory.JTA_RESOURCE);

Then, in the xml plan, you just say
<gbean namePart="defaultRegistry" class="...
and you get
geronimo.server: 
J2EEServer=geronimo,J2EEApplication=null,J2EEModule=org/apache/ 
geronimo/Server,j2eeType=CORBAResource,name=defaultRegistry


Also, the names here imply that you are running in openejb rather  
than  full geronimo.  Is this correct?

I don't think so.  I have a temp plan in the directory  
geronimo\modules\assembly, I started working from the  
geronimo\modules\assembly\j2ee-server-plan.xml.
As noted above, the domain name may be causing nothing to be found.
Hope this helps
