On the tutorial page: http://appfuse.org/display/APF/Using+Hibernate

the following line of code:

public interface PersonDao<T, PK extends java.io.Serializable> extends GenericDao {

should be

public interface PersonDao extends GenericDao <Person, Long> {

also, the following line:

private PersonDao<Person, Long> personDao = null;

it should then be modified as:

private PersonDao personDao = null;
