This turned out to be a typo.  This should be:  <ref-name>mGball</ref-name> 

Also add the "<jndi-name>" tag under the openejb portion of the geronimo application plan
xml file as below:

<module>
         <ejb>magicGball-ejb.jar</ejb>
         <openejb-jar xmlns="http://www.openejb.org/xml/ns/openejb-jar" configId="ejb"
             parentId="org/apache/geronimo/Server">
         <import>
              <uri>org/apache/geronimo/ServerCORBA</uri>
         </import>
             <enterprise-beans>
                 <session>
                     <ejb-name>MagicGBall</ejb-name>
                     <jndi-name>MagicGBall</jndi-name>
                     <tss-link>SSLClientPassword</tss-link>
                 </session>
             </enterprise-beans>
         </openejb-jar>
     </module>

Now I am getting the following exception when I ran the client:

And the exception is from the following cast of MagicGBallClient.java:

Context myEnv = (Context) ctx.lookup("java:comp/env");
Object objref = myEnv.lookup("mGball");
MagicGBallHome ejbHome = (MagicGBallHome) PortableRemoteObject.narrow(objref,
MagicGBallHome.class);

Any help is appreciated!

Thanks, Lin
