J2ee RI doesn't understand client identity

Question

Hi all,
I wrote a client application that try to use
an EJB session bean deployed in J2EE RI App.Server.
I specified the following data to connect to the server:
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi. ......");
p.put(Context.PROVIDER_URL, "iiop://localhost:1050");
p.put(Context.SECURITY_PRINCIPAL, <my user>);
p.put(Context.SECURITY_CREDENTIALS, <ma password>);
Previously, I created <my user> (with password <my password>) inside J2EE RI.
When I run (with runclient) my client application the login fails.
Server side J2EE RI doesn't recognize my user
(in a debug print inside Session Bean's ejbCreate()method,
I see that Client Identity is "guest").
Anybody can suggest me where I'm wrong ?
Many Thanks in advance
Moreno

I think, that the object you put as Context.SECURITY_PRINCIPAL must implement the interface java.security.Principal.
Why don't you use a callback-handler in your client. This is the specified way for a client to authentify.
application-client.xml:
=======================
<application-client>
<callback-handler>test.appclient.SimpleCallbackHandler</callback-handler>
</application-client>
Example for a simple Callback-Handler
(in your client, not on the server!):
======================================
package test.appclient;
import java.io.IOException;
import javax.security.auth.callback.Callback;
import javax.security.auth.callback.NameCallback;
import javax.security.auth.callback.PasswordCallback;
import javax.security.auth.callback.CallbackHandler;
import javax.security.auth.callback.UnsupportedCallbackException;
public class SimpleCallbackHandler implements CallbackHandler
public void handle(Callback[] callbacks) throws IOException, UnsupportedCallbackException
for(int i=0; i<callbacks.length; i++)
if( callbacks[i] instanceof NameCallback )
NameCallback nc = (NameCallback)callbacks;
nc.setName( "yourName" );
else if( callbacks[i] instanceof PasswordCallback )
PasswordCallback pc = (PasswordCallback)callbacks[i];
pc.setPassword( "yourPassword".toCharArray() );
else
throw new UnsupportedCallbackException(callbacks[i]);
