trying to connect to an EJB in WLS 8.1sp3 JDK1.4.2_04 with IIOP client JDK1.4.2_06

[mh...@valista.com]

I have weblogic.jar in the classpath of the client (tried wlclient too,
same result)

the code sample I use:
Properties props = new Properties();
props.put(Context.PROVIDER_URL,
"iiop://calcutta:31001");
// "t3://calcutta:31001");
props.put(Context.INITIAL_CONTEXT_FACTORY,
"com.sun.jndi.cosnaming.CNCtxFactory");
// "weblogic.jndi.WLInitialContextFactory");

MerchantServiceHome home = null;
try {
home = MerchantServiceLocator.getHome(props);
} catch (NamingException e) {
System.out.println(e.getCause().getMessage() + "_" + e);
return;
}

note that it works fine if I use the t3 protocol and the weblogic
initial context factory

here's the error I get:
org.omg.CORBA.COMM_FAILURE: vmcid: SUN minor code: 201 completed:

What am I missing ? Is there some server side setting I have to change
(I checked that the Enable IIOP flag is checked in the console) ? Do I
need to specify some iiop options when doing the ejbc (I thought it was
done by default)?
