Reference EJB Binding problem
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:1.2@localhost
: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,
Vamsi

Thanks Raymond. It works now. I will report the issue to Yoko mailing
lists.

Re: Reference EJB Binding problem

Hi,
Thank you for the hint. I'm able to identify an issue in the Yoko ORB. The
problem is in class:
http://svn.apache.org/viewvc/incubator/yoko/trunk/core/src/main/java/org/apache/yoko/orb/CORBA/InputStream.java?revision=555715&view=markup
Method "private String getIDLStubClassName(Class c)" doesn't support the
variant of stub names (org.omg.stub.*) defined by
http://www.omg.org/docs/formal/03-09-04.pdf (section 1.4.6).
As a workaround/fix, I changed the ejb binding code (EJBObjectFactory) to
use org.omg.stub.javax.rmi._Remote_Stub.class to read the CORBA object. With
this, the samples are now working fine on Geronimo 2.0 branch. The code was
checked in under http://svn.apache.org/viewvc?view=rev&rev=562382.
Thanks,
Raymond

We have done some further investigation and here are the findings:
We have configured the J2SE enviroment to use Yoko ORB (the one used by
Geronimo) instead of the JVMs and running the testcase resulted in a
MarshalException. We suspect it is an issue with Yoko ORB.

I suspect a something somewhere is using the wrong class loader, but its
hard to tell precisely where without being able to debug by stepping through
the code. Any chance you could make your code available somewhere (a zip
file in a jira or anywhere?) so we can try it?
