Casey,
Since the error pages do have access to your request implicit object, you
could,
as the first action on every non-error page, simply set an attribute of your
request with a label identifying the page as the value of the attribute.
If an error occurs, this value can be extracted by the error page from the
request
object to identify where the error occurred.

Example....
----------------------------------------------------------------------------
-------
<%-- Page causing error: --%>
<%@ page errorPage="Error.jsp" import="java.util.*" %>
<%
request.setAttribute("from", "JSP Error Page");
%>
<HTML>
<Head>
<Title> Generate JSP Error </Title>
</Head>
<%
Integer.parseInt("Make JSP Integer Parsing Error"); // Should throw
exception
%>
</Html>
----------------------------------------------------------------------------
--------
<%-- Errorpage dealing with error: Error.jsp --%>
<%@ page isErrorPage="true" import="java.util.*" %>
<% String originator = (String) request.getAttribute("from"); %>
<HTML>
<Head>
<Title> Common Error Page for Servlets & JSPs </Title>
</Head>
<BODY>
<H1 ALIGN=center> Common Error Page for Servlets & JSPs </H1>
<HR>
<BR> <BR>
This error was generated either in <%= originator %> by attempting to
parse a string as an integer. The string used for this purpose was NOT
a string representation of an integer, so a NumberFormat Exception was
raised.
<BR> <BR>
<%
PrintWriter p = new PrintWriter(out, true); // Create PrintWriter with
JSPWriter
exception.printStackTrace(p); // Use PrintWriter for output
%>
</PRE>
</BODY>
</HTML>

> I tried the following to no avail <%@ page
> errorPage="Y.jsp?source=X.jsp"
