Following is my client code

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

}
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(){}
