Acces value between two jsp with jstl

Question 1

Here is the sample code to access value between two jsp with jstl.

First JSP

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

<html>
  <body>
    This JSP stores the 'para' in a session-scoped variable where
    the other JSPs in the web application can access it.
    <p />
    <c:set var="para" value="${41+1}" scope="session"  />

     Click <a href="displayAttributes.jsp">here</a> to view it.
  </body>
</html>

Second JSP (displayAttributes.jsp)

<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core" %>

<html>
  <head>
    <title>Retrieval of attributes</title>
  </head>
  <body>
    The para is <c:out value="${sessionScope.para}" /> <br/>
  </body>
</html>

Set the attribute in session scope

<c:set var="para" value="${41+1}" scope="session"  />

Get the attribute from session scope

<c:out value="${sessionScope.para}" />

More samples on other scopes.

    <%-- Set scoped variables --%>
    <c:set var="para" value="${41+1}" scope="page" />
    <c:set var="para" value="${41+1}" scope="request" />
    <c:set var="para" value="${41+1}" scope="session" />
    <c:set var="para" value="${41+1}" scope="application" />

    <%-- Print the values --%>
    <c:out value="${pageScope.para}" />
    <c:out value="${requestScope.para}" />
    <c:out value="${sessionScope.para}" />
    <c:out value="${applicationScope.para}" />

Question 2

you can put the value(cursor.getId_node()) in 'request' scope and in second jsp , get the value from request
