Subject: Ejb web services and jndi name
Content-Type: text/plain; charset=ISO-8859-15; format=flowed
Content-Transfer-Encoding: 7bit

Hi all,
I'm a new user of geronimo.
To complete my bachelor thesis, i need to create simples web services
with ejb.
I create the Jar file and deploy it on application server, but, when i
try to connect my client
to my web services, i receive the message that the jndi name isn't correct.
I think that the error was in the deployment xml of the client, but i
don't be able to get the wsdl of the service
via browser (i try with the url written in the wsdl, but, evidently, it
isn't correct).
Please, i must deliver my work monday morning.

endpoint interface
package org.eclipse.Ciao;

import java.rmi.RemoteException;

public interface CiaoWSService extends Remote{
    public String getString(String name) throws RemoteException;

    CiaoWS create() throws RemoteException, CreateException;
}

import java.rmi.RemoteException;
import javax.ejb.*;

public interface CiaoWS extends EJBObject{

    public String getString(String name) throws RemoteException;

    }
    public void ejbCreate(){}
    public void ejbRemove(){}
    public void ejbActivate(){}
    public void ejbPassivate(){}
