Привет, я пытаюсь заполнить поле со списком в стойках 1.2, но у меня есть некоторые исключения, вот мой код
dto
public class GroupDTO {
public GroupDTO() {
// TODO Auto-generated constructor stub
}
private String value;
private String lable;
public GroupDTO(String value,String lable){
this.value = value;
this.lable = lable;
}
public String getLable() {
return lable;
}
public void setLable(String lable) {
this.lable = lable;
}
public String getValue() {
return value;
}
}
класс действия
public class DualListBoxAction extends Action {
@Override
public ActionForward execute(ActionMapping mapping, ActionForm form,
HttpServletRequest request, HttpServletResponse response)
throws Exception {
// TODO Auto-generated method stub
List<GroupDTO> groupList = new ArrayList<GroupDTO>();
GroupDTO groupDTO = null;
groupDTO = new GroupDTO("1", "group1");
groupList.add(groupDTO);
groupDTO = new GroupDTO("2", "group2");
groupList.add(groupDTO);
groupDTO = new GroupDTO("3", "group3");
groupList.add(groupDTO);
groupDTO = new GroupDTO("4", "group4");
groupList.add(groupDTO);
HttpSession session = request.getSession();
session.setAttribute("groupList", groupList);
return mapping.findForward("success");
}
}

public class DualListBoxForm extends ActionForm {
/**

private static final long serialVersionUID = 1L;

}
public void setGroupName(String groupName) {
this.groupName = groupName;
