I have a JSP page that has an error page defined. This works, however depending upon where the error occurs in the jsp page all of the page up to the point of the error is also displayed. If I induce an error at the top of the page just the error page is visible. If I induce an error somewhere later in the page say in a table cell the contents of the error page appears here with the rest of the page. It is as if the error page is an include.

Error page looks like this:
<%@ page contentType="text/html" %>
<%@ page isErrorPage="true" %>
<html>
<link rel="stylesheet" type="text/css" href="../monstyle.css">
<h1>Sorry! an error has occured.</h1>
<blockquote>
Error message:<%= exception.getMessage() %><br>
Java exception:<%= exception.toString() %><br>
JSP requested:<%=request.getServerName()+request.getRequestURI() %><br>
</blockquote>
<% System.out.println("jsp_error_page: Error in JSP: " + request.getServerName()
+ request.getRequestURI() + ". Exception was: "+exception.toString()); %>
<h2>Please contact support.</h2>
</html>
Page creating the error:
<%@ page contentType="text/html" %>
<%@ page errorPage="/MonError.jsp" %>
<%@ page import="java.util.*" %>
<html>
<link rel="stylesheet" type="text/css" href="../monstyle.css">
<body>
<h2>Group List</h2>
<table cellpadding="0" cellspacing="0">
<tr>
<th>Group Code</th>
<th>Group Description</th>
<th>Edit</th>
<th>Delete</th>
<th>Copy</th>
</tr>
<jsp:useBean id="mglb" scope="request" class="com.primur.monitor.MonGroupListBean"/>
<%
String rowStyle = "tr1";
Vector grouplist = (Vector)request.getAttribute("grouplist") ;
for (Enumeration e = grouplist.elements() ; e.hasMoreElements() {
mglb =(com.primur.monitor.MonGroupListBean)e.nextElement();
%>
<tr class="<%=rowStyle %>">
<td> <a title="View" href="MonGroupMaint?mode=view&id=<%= mglb.getGrgrpc() %>">
<%= mglb.getGrgrpc() %></td>
<td><%= mglb.getGrdesc() %></td>
<td>
<p align="center">
<a href="MonGroupMaint?mode=edit&id=<%= mglb.getGrgrpc() %>">
<img border="0" src="../edt.gif" width="22" height="20" alt="Edit"></a></td>
<td>
<p align="center">
<a href="MonGroupMaint?mode=delete&id=<%= mglb.getGrgrpc() %>">
<img border="0" src="../del.gif" width="22" height="20" alt="Delete"></a></td>
<td>
<p align="center">
<a href="MonGroupMaint?mode=copy&id=<%= mglb.getGrgrpc() %>">
<img border="0" src="../cpy.gif" width="22" height="20" alt="Copy"></a></td>
</tr>
<%
if (rowStyle=="tr1"){
rowStyle = "tr2";
}
else {
rowStyle = "tr1";
}
}
<%
if (true)
throw new Exception("This is my test"); // test error page
%>
%>
</table>
<p></p>
<a href="MonGroupMaint?mode=add">Add New User</a>
</body>
<html>
The error page appears in a cell of the page's table.

That is because at least one bufferload has already been flushed when the error occurs. You might try increasing the buffer size in the page directive.
