Error connecting to an EJB 3.0 Remote on OC4J 10.1.3.2 from Tomcat

Question

Hi, I want to connect to a Remote Session Bean running on the OC4J 10.1.3 and it doesn´t work.
I have connected to it from a java standalone application using:
public static void main(String [] args) {
try {
final Context context = getInitialContext();
SessionEJB sessionEJB = (SessionEJB)context.lookup("java:comp/env/ejb/SessionEJB");
System.out.println(sessionEJB.mergeEntity(""));
System.out.println( "hola" );
} catch (Exception ex) {
ex.printStackTrace();
private static Context getInitialContext() throws NamingException {
Hashtable env = new Hashtable();
// Standalone OC4J connection details
env.put( Context.INITIAL_CONTEXT_FACTORY, "oracle.j2ee.naming.ApplicationClientInitialContextFactory" );
env.put( Context.SECURITY_PRINCIPAL, "oc4jadmin" );
env.put( Context.SECURITY_CREDENTIALS, "passw" );
env.put(Context.PROVIDER_URL, "ormi://localhost:23791/ejb3jar");
return new InitialContext( env );
with this application-client.xml file:
<?xml version = '1.0' encoding = 'windows-1252'?>
<application-client xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee http://java.sun.com/xml/ns/j2ee/application-client_1_4.xsd" version="1.4" xmlns="http://java.sun.com/xml/ns/j2ee">
<display-name>Model-app-client</display-name>
<ejb-ref>
<ejb-ref-name>ejb/SessionEJB</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
<remote>ar.com.eds.ejb3.model.SessionEJB</remote>
<ejb-link>SessionEJB</ejb-link>
</ejb-ref>
thats works fine, but when I try to use the same solution from a jsf proyect running on a Tomcat 5.5.20, it fails with this error:
Caused by: java.lang.RuntimeException: Error while creating home.

Hi, Rick
Thanks for your help.
I deleted de application-client.xml file, added the following lines to the web.xml file:
     <ejb-ref>
          <ejb-ref-name>ejb/SessionEJB</ejb-ref-name>
          <ejb-ref-type>Session</ejb-ref-type>
          <remote>ar.com.eds.ejb3.model.SessionEJB</remote>
     </ejb-ref>
and now I´m using oracle.j2ee.rmi.RMIInitialContextFactory
there is no error, and it doesn´t throw any exception but the following line returns null.
SessionEJB sessionEJB = (SessionEJB)context.lookup("java:comp/env/ejb/SessionEJB");
Its seems the lookup method finds the remote ejb because it doesn´t fail, but it returns null.
Any idea what is wrong?
Mauricio.
