I'm very new to seam, jsf, ejb3... But I thought I could get the demo running with the instructions provided. I'm having trouble with the Lab 3 Step 1. I don't know where to put the @End, is this in the NewHotelAction class?

yes exactly.

You just need to specify @End on the saveHotel() method, it is the last method that is interesting in our conversation. It is called from the JSF page and will let Seam destroy the conversation at the end of the method call.

So your class should look like this now:

package org.jboss.seam.example.booking;

import java.util.*;

import javax.ejb.*;
import javax.persistence.*;

import org.jboss.seam.annotations.*;
import org.jboss.seam.annotations.datamodel.*;
import org.jboss.seam.log.Log;

@Stateless
@Name("newHotel")
public class NewHotelAction
 implements NewHotel
{
 @PersistenceContext
 private EntityManager em;

 @In(create=true)
 private Hotel hotel;

 @Logger
 private Log log;

 @End
 public String saveHotel()
 {
 log.info("Saving hotel #{hotel}");
 em.persist(hotel);
 log.info("Created hotel id #{hotel.id}");
 return "/newHotelCreated.xhtml";
 }
}
