[Maxime Colas des Francs]

Hi

thks for your response, but here is my code, i don't understand where the 
response is commited !

_____________

<%@ page contentType="text/html; charset=iso-8859-1" language="java" 
errorPage="/error_jsp.jsp"%>
<%@ taglib prefix="c" uri="http://java.sun.com/jstl/core"; %>
<%@ taglib prefix="log" uri="http://jakarta.apache.org/taglibs/log-1.0"; %>
<%@ taglib prefix="sql" uri="http://java.sun.com/jstl/sql"; %>

<sql:query var="ctcRow">
   SELECT DISTINCT email FROM ctc ORDER by email
</sql:query>
<c:forEach items="${ctcRow.rows}" var="row">

        <log:info category='<%= request.getRemoteUser() %>'>
           <c:out value="${row.email}"/>
        </log:info>
</c:forEach>

<jsp:forward page="/index.jsp"/>

___________

if i put a autoFlush="false" in page directive and a <% out.flush(); %> 
just before the forward i have a bufferOverflow ...

Howdy,
Both errors are fairly clear and essentially the same.  You can't
forward or redirect a response that's been committed, i.e. written to.
If you're going to forward or redirect a response, you must do so before
writing to the response.  You can read the JavaDoc for
HttpServletResponse#sendRedirect and RequestDispatcher#forward.
