****************************************************
Following is my client code

private ConfigureRemoteInterface getRemote() {



ConfigureRemoteInterface configureRemoteInterface = null;
Properties p = new Properties();
p.put(Context.INITIAL_CONTEXT_FACTORY,
"org.jnp.interfaces.NamingContextFactory");
p.put(Context.PROVIDER_URL, "localhost:1099");
p.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
InitialContext ctx = null;
try {
ctx = new InitialContext(p);
} catch (NamingException e) {
e.printStackTrace();
}
Object obj = null;
try {
obj = ctx.lookup("ejb/ConfigureJndi");
} catch (NamingException e) {
e.printStackTrace();
}
if(obj instanceof ConfigureHomeInterface){
}else if(obj instanceof ConfigureRemoteInterface){
System.out.println(ConfigureCameraAction.class.getName()+">>>>>>>>>>>>OBJ IS OBJECT>>>>>>>>>");
}
ConfigureHomeInterface configureHomeInterface=null;
configureHomeInterface = (ConfigureHomeInterface) PortableRemoteObject
.narrow(obj, ConfigureHomeInterface.class);

try {
configureRemoteInterface = configureHomeInterface.create();
} catch (RemoteException e) {
e.printStackTrace();
} catch (CreateException e) {
e.printStackTrace();
}

return configureRemoteInterface;
}

*****************************************
HOME class as follows

import java.rmi.RemoteException;
import javax.ejb.CreateException;
import javax.ejb.EJBHome;


public interface ConfigureHomeInterface extends EJBHome {
public ConfigureRemoteInterface create() throws RemoteException, CreateException;
}

*******************************************
Remote as folows

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



public interface ConfigureRemoteInterface extends EJBObject {


public String sayHello() throws RemoteException,DataHandlerException ;

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

(SessionContext sc ) {}


}


Any help at the earliest is always welcome :)
Thanks in advance !
