java 1.6, struts 및 jstl-1.2.jar을 사용하고 jstl 핵심 태그를 사용하여 jsp로 목록을 인쇄하려고합니다. 세션 범위 속성을 사용하면 (${sessionScope.myList}), 핵심 태그는 값이전달 후 요청 속성을 사용할 수 없습니다. 세션 속성 만 사용할 수 있습니다.

ActViewTender.java
입니다 핵심 태그에 의해 촬영되지 않도록, (${requestScope.myList})을 제대로 값을 얻을하지만 난 요청을 사용할 때 범위 속성
public class ActViewTender
extends Action {
static Logger logger = Logger.getLogger(ActViewTender.class);
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response) throws Exception {
String realPath = getServlet().getServletContext().getRealPath("/WEB-INF/log4jConfiguration.xml");
DOMConfigurator.configure(realPath);
try {
ReverseAuctionTender reverseAuctionTender = new ReverseAuctionTender();
ISupplier supplier = new Supplier();
List<TenderEnt> tendeList = reverseAuctionTender.ViewReverseAuctionTender(conn, strSupID);
List<TenderEnt> ReverseAuctionTenderList = new ArrayList<TenderEnt>();
List<String> watchList = supplier.getAddtoWatchListTender(conn, strSupID);
try {
for (TenderEnt tenderEnt : tendeList) {
String isWatched = "";
for (String wl : watchList) {
if (wl.equals(tenderEnt.getTenderNo().trim())) {
isWatched = "watched";
}
}
tenderEnt.setIsWatched(isWatched);
ReverseAuctionTenderList.add(tenderEnt);
}
request.setAttribute("myList", ReverseAuctionTenderList);
}
catch (Exception e) {
e.printStackTrace();
logger.fatal(e.getMessage());
}
forward = mapping.findForward("SupplierMain");
}
return forward;
}
}
듣고는 JSP 코드
내가 (request.getSession().setAttribute("myList", ReverseAuctionTenderList); 및
<c:forEach items="${sessionScope.myList}" var="tender">와) 서블릿에서 세션 변수로 설정했을 때이 같은 목록만을 얻을 결과로
<c:forEach items="${requestScope.myList}" var="tender">
<div class="small-12 tender auction-type online-tenders">
<div class="small-12 tender-number"><c:out value="${tender.tenderNo}"></c:out></div>
<div class="small-12 tender-detail">
<div class="small-12 medium-7 large-9 columns collapse tender-title">
<h4>${tender.description}</h4>
</div>
</div>
</div>
</c:forEach>
그것 때문이다
이것은 스트럿츠 매핑
