basically your html headers have already been written before you did a forward. do not do this. if you need to forward or sendRedirect to another page, do it before writing any html out.

    Hi guys, here's a strange, strange thing.  I have a jsp page, which includes another page.  Basically,
 
-----------------------------------------------------------
page1.jsp:
 
<%@ page ... %>
<%
    if (request.getParameter("checkpage").equals("page2"))
    {%>
         <%@ include file="page2.jsp" %>  
<%}
    else ...
%>
-----------------------------------------------------------
page2.jsp:
 
<%@ page ... %>
<%
    do a database update
%>
<jsp:forward page="page1.jsp">
    <jsp:param name="checkpage" value="page2" />
</jsp:forward>
 
-----------------------------------------------------------
 
So anyway, this works fine, and has worked fine for some time.  All of a sudden though, I am getting the error:
 
java.io.IOException: Data has already been flushed to the client

This appears to be a problem with orion, but I have NO idea what might be causing it or how to fix it, 
despite a great deal of searching.  I am running orion 1.4.5...  Can ANYONE shed some light on this?  It is driving me CRAZY!!
