Reference EJB Binding problem

[Vamsavardhana Reddy]

Hi,

I have modified the Calculator sample to use an EJB binding for addService.
I have deployed an AddService bean in Geronimo 2.0-SNAPSHOT Tomcat server.
I am using an EmbeddedSCADomain to run the sample.  I am facing a strange
problem.  When I run the sample in J2SE environment (I actually modified the
testcase in sca/modules/binding-ejb to run this sample) everything runs
fine.  I see that the EJB is invoked for AddService.  But when I run this
sample inside Geronimo using the tuscany-plugin (see
http://cwiki.apache.org/confluence/display/TUSCANYWIKI/Tuscany+Geronimo+Integrationfor
details on the Geronimo Tuscany Integration details), I am getting "
java.rmi.MarshalException: Unable to create stub for class java.lang.Object;
nested exception is:
org.omg.CORBA.MARSHAL: Unable to create stub for class java.lang.Object:
vmcid: Apache minor code: 0x2e completed: No "

Here is the reference ejb binding xml-fragment from Calculator-new.composite

        <reference name="addService">
            <interface.java interface="calculator.AddService"/>
            <binding.ejb uri="corbaname:iiop:[EMAIL PROTECTED]
:1050#AddServiceBean"/>
        </reference>

Here is the session bean definition in ejb-jar.xml:
      <session>
         <description>AddService Bean</description>
         <display-name>AddServiceBean</display-name>
         <ejb-name>AddServiceBean</ejb-name>
         <home>calculator.AddServiceHome</home>
         <remote>calculator.AddService</remote>
         <local-home>calculator.AddServiceLocalHome</local-home>
         <local>calculator.AddServiceLocal</local>
         <ejb-class>calculator.AddServiceBean</ejb-class>
         <session-type>Stateless</session-type>
         <transaction-type>Container</transaction-type>
      </session>

And the binding in openejb-jar.xml:

        <session>
          <ejb-name>AddServiceBean</ejb-name>
          <jndi-name>AddServiceBean</jndi-name>
           ...
        </session>


Any ideas on what is making the difference in J2SE and J2EE enviroments in
this context?  Any help in resolving this problem is appreciated.

Thanks and best regards,
