JSP 리디렉션 제출 값

이 jsp가 있는데 일부 입력 데이터를 처리하려고합니다. 왜 현재 jsp는 값을 제출하고 서블릿을 실행하기를 기다리지 않았습니까? 사이트는 즉시 정의 된 다음 페이지로 리디렉션합니다. 나는 페이지를 보여주고 싶다. 사용자는 가치를 부여한 다음 리디렉션해야한다. 여기JSP 리디렉션 제출 값

내 코드 :

<%@ page contentType="text/html" pageEncoding="UTF-8"%> 
<%@ include file="/resources/taglibs.jsp"%> 

<% 
session.setAttribute("MyName", System.getProperty("user.name")); 
request.setAttribute("hideNav", true); 
%> 

<fmt:setLocale value="${lang}" /> 
<fmt:bundle basename="messages"> 
<t:template> 
    <jsp:attribute name="header"> 
     <fmt:message key="topic.bag_transfer" /> 
    </jsp:attribute> 

    <jsp:attribute name="navigation_static"> 
     <li><a href="info"><font size="+0.1">${lang}</font></a></li> 
    </jsp:attribute> 
    <jsp:body> 
     <p class="msg"> 
      <fmt:message key="all.message" /> 
      <c:out value="${requestScope.Message}" /> 
     </p> 
     <%--Form--%> 
     <form method="post" action="login"> 
      <div> 
       <p class="f_head"> 
        <fmt:message key="all.user" /> 
       </p> 
       <p class="f_form"> 
        <input id="1" class="f_txt" type="text" name="login" /> 
       </p> 
       <%--button--%> 
       <p class="f_form_bl"> 
        <input id="3" class="f_btn" type="submit" name="btn" value="Weiter" /> 
       </p> 
      </div> 
     </form>  
    </jsp:body> 
</t:template>

   <li><a id="10" href="bag_scan_start_location"> <fmt:message key="topic.bag_transfer" /></a></li>

및 web.xml을 같이 topic.jsp에 연결된 주제 href는 서블릿을 실행할 것이다. 즉시. JSP가 으로 표시되지 않는 이유는 무엇입니까??

아니요 위의 내용을 참조하십시오 ... – Tim

코드 조각간에 연결하기가 약간 어려워요? 시도해 보자. href 링크를 클릭하면 BagScanStartLocation 서블릿에 GET 요청을 보낸다. 그런 다음 doGet을 호출 한 다음 doPost를 호출하고 jsp로 색상 입력을위한 양식을 전달합니다. 그리고 즉시 다음 서블릿으로 리디렉션됩니까? 아마도 doPost 메서드에서 앞으로 발생하기 때문에 발생합니다. BagScanStartLocation 서블릿에서 doPost에서 doGet으로 모두 바꾸어보십시오. –

리디렉션 및 전체 web.xml을 만드는 전체 JSP를 표시하십시오. –
