In your error page, the variable "exception" is set to the exception
(if any). You can get the error message and stack trace from the
exception like this:
<p>Exception message: <%= (exception == null) ? "" :
exception.getMessage() %></p>
<%
String stStack = "";
if (exception != null) {
java.io.StringWriter sw = new java.io.StringWriter();
exception.printStackTrace(new java.io.PrintWriter(sw));
stStack = sw.toString();
}
%>
<p>Stack trace:</p>
<pre>
<%= stStack %>
</pre>
(Note: For clarity I omitted some important stuff like sanitizing the
output to prevent people from stuffing nasty HTML/Javascript into the
error messages.)
