Pass jstl sql query result to jsp

Question

Hi I have the following code which works perfectly
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<sql:setDataSource dataSource="jdbc/dbtest"/>
<sql:query var="items" sql="SELECT * FROM homepagesubscriptions">
</sql:query>
<table border="0" align="center" valign="top">
<c:forEach var="row" items="${items.rows}" begin = "0" end="10" >
               <tr>
               <td>
                    <img src="${row.imgurl}" width="100" height = "100"></a>
               </td>
               <tr>
</c:forEach>
</table>   Now what I want is to perform the query in one page and then display the data in another, as such
index.jsp
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<sql:setDataSource dataSource="jdbc/dbtest"/>
<sql:query var="items" sql="SELECT * FROM homepagesubscriptions">
</sql:query>
<!-- NOT SURE WHAT TO DO HERE
<jsp:useBean id="resultBean" scope="request"
     class="javax.servlet.jsp.jstl.sql.ResultSupport" />
<jsp:setProperty name="rs" property="rs" />
<jsp:forward page="test.jsp" />
-->
    test.jsp
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %>
<c:set var="items" value="${resultBean}" />
<table border="0" align="center" valign="top">
<c:forEach var="row" items="${items.rows}" begin = "0" end="10" >
               <tr>
               <td>
                    <img src="${row.imgurl}" width="100" height = "100"></a>
               </td>
               <tr>
</c:forEach>
</table>   I know in index.jsp I can use jsp forward and usebean but am not sure how to? What type is the result from the query? thanks

Take a look at the "scope" attribute of the <sql:query> tag.
query.jsp:
<%@ taglib prefix="sql" uri="http://java.sun.com/jsp/jstl/sql" %>
<sql:setDataSource dataSource="jdbc/dbtest"/>
<sql:query var="items" scope="request" sql="SELECT * FROM homepagesubscriptions"/>
<jsp:forward page="test.jsp" />and then test.jsp:
<%@ taglib prefix="c" uri="http://java.sun.com/jsp/jstl/core" %> 
<table border="0" align="center" valign="top">
<c:forEach var="row" items="${items.rows}" begin = "0" end="10" >
               <tr>
               <td>
                    <img src="${row.imgurl}" width="100" height = "100"></a>
               </td>
               <tr>
</c:forEach>
