arquivo de persist�ncia:

             <property name="hibernate.show_sql" value="true"/>  
         </properties>  
     </persistence-unit>  
 </persistence>


Essa classe retorna o entity manager
[code:1:1e29369caf]
 public class JpaUtil {    
   
      private static JpaUtil me;    
     private EntityManagerFactory factory;    
           
      private JpaUtil () {    
          factory = Persistence.createEntityManagerFactory("pu1");    
      }    
         
     public static JpaUtil getInstance() {    
          if (me == null) {    
              me = new JpaUtil();    
          }    
          return me;    
      }    
          
     public EntityManager createEntityManager() {    
         EntityManager em = factory.createEntityManager();    
          em.getTransaction().begin();    
          return em;    
      }    
  }

Esse � meu managedBean

 public class FirstJsfandjpa {    
      
     private List<People> people;    
          
     public FirstJsfandjpa() {    
          EntityManager em = (EntityManager) JpaUtil.getInstance().createEntityManager();    
         people = em.createQuery("select pl from People pl").getResultList();    
          em.getTransaction().commit();    
          em.close();    
      }    
      
      public List<People> getPeople() {    
          return people;    
      }    
      
      public void setPeople(List<People> people) {    
          this.people = people;    

  }

quando eu executo dessa classe td funciona

 public class Execute {    
    
      List<People> people = new FirstJsfandjpa().getPeople();    
         
     public static void main(String[] args) {    
             
         List<People> people = new FirstJsfandjpa().getPeople();    
             
          for (People pl: people) {    
             System.out.println(pl.getName());    
          }    
      }    
  }

Mas quando eu executo de uma p�gina JSF no tomcat d� erro:

Opa !

Falta as bibliotecas do JPA

Tente colocar no LIB do TOMCAT:

hibernate-entitymanager.jar

E teste.
