I use JPA (hibernate) to persist.
An example of action that use prepare to load a person object from
transactional manager. When the validate fails and it return back to the
input page the request ends and the transaction persists the dirty user
object to database. The dirty user object should not be persisted if the
validation fails.:
public class PersonAction extends BaseAction implements Preparable {
private PersonManager personManager;
private Person person;
public void prepare() {
person = personManager.getPerson(id);
}
public String savePerson() {
manager.savePerson(person);
return SUCCESS;
}
public void validate() {
if (person.firstName.length < 5 and person.firstName > 10) {
addActionError("Firstname length should be between 5 and 10
characters.");
}
}
}
