Unable to access Remote EJB with jndi.properties in classpath

Question

Hi
I'm trying to use remote interfaces with my adf web layer.
Created remote datacontrol for my model part and my model EAR is deployed in another Oracle App Server instance(S1).
My web layer is deployed in another Oracle App Server(S2). My page def uses the remote interfaces.
Following are the files which are needed to have ejb ref entry.
---- orion-web.xml ----
<?xml version = '1.0' encoding = 'windows-1252'?>
<orion-web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="http://xmlns.oracle.com/oracleas/schema/orion-web-10_0.xsd"
schema-major-version="10" schema-minor-version="0"
servlet-webdir="/servlet/" >
<ejb-ref-mapping name="MySessionEJB" location="MySessionEJB"
remote-server-ref="true"
jndi-properties-file="jndi.properties"></ejb-ref-mapping>
</orion-web-app>

and this jndi.properties file in placed in the WEB-INF/classes folder.
java.naming.factory.initial=oracle.j2ee.rmi.RMIInitialContextFactory
java.naming.security.principal=oc4jadmin
java.naming.security.credentials=welcome123
java.naming.provider.url=opmn:ormi://S1:6003:Test_Instance/test-ejb
The same web application if I run it in Jdeveloper its able to open the welcome.jspx which calls the remote EJB method on load. But when I deploy it Oracle Server 10.1.3.1.0 the error "500 Internal Server Error" shows up and in log file following exception can be found
avax.faces.el.EvaluationException: oracle.jbo.JboException: JBO-29000: Unexpected exception caught: oracle.jbo.JboException, msg
=JBO-29000: Unexpected exception caught: javax.naming.NameNotFoundException, msg=MySessionEJB not found
Seems like the jndi properties is ignored during the Context creation for lookup.
Please advice where I'm missing the configuration.
