Hi, Michael
You could use a "searchCriteria" approach that I use. I use it with
spring/hibernate, but it could be used with any bussiness layer. Ok I'll try
to explain in general:
Suppose we have a PeopleCriteria class
****
class PeopleCriteria {
String name;
String surname;
Boolean sortByName;
Boolean sortBySurname;
Boolean asc;
//Getters and Setters
}
****
we store object of this criteria in session, so the ActionBean could look
like that:
***
public class PeopleActionBean extends BaseActionBean {
PeopleCriteria criteria;
public PeopleCriteria getCriteria() {
if (criteria == null) {
criteria =
(PeopleCriteria)session.getAttribute("peopleSearchCriteria");
}
return criteria;
}
List<Person> people;
public List<Person> getPeople() {
if (people == null) {
people =
services.getPeopleService().getPeopleByCriteria(getCriteria());
}
return people;
}
}
***
You could also have a form with search parameters, it is flexible approach,
for example you could have parameter like "?criteria.name=Alex" and it will
be binded to search criteria object.
You just have to code the logic of method List<Person>
getPeopleByCriteria(PeopleCriteria criteria);
May be this approach isn't so good, I'd like to see other ways if someone
would like to show.
