We have the list of map in action class. The following sample code show that
how to iterate list of map in jsp file using struts2 iterator. In this, status attribute will give the status of current iteration.
import com.opensymphony.xwork2.ActionSupport;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
public class mapTest extends ActionSupport {
public List<Map> listofmap;
public String execute(){
listofmap = new ArrayList();
Map map = new HashMap();
map.put("a", "America");
map.put("b", "Brazil");
map.put("c", "China");
listmap.add(map);
Map map2 = new HashMap();
map2.put("d", "Denmark");
map2.put("e", "Europe");
map2.put("f", "France");
listofmap.add(map2);
return SUCCESS;
}
}
