Hi,
I think the tutorial
http://struts.apache.org/2.1.6/docs/struts-2-spring-2-jpa-ajax.html is
misleading(?). In the PersonServiceImpl class, the method:
public void save(Person person) {
if (person.getId() == null) {
em.persist(person);
} else {
em.merge(person);
}
}
has an error of 'The operator == is undefined for the argument type(s) int'.
Because
the default value would be 0 per
http://java.sun.com/docs/books/tutorial/java/nutsandbolts/datatypes.html. I
think it should be:
if (person.getId() == 0)
