>          Issue Type: Improvement
>          Components: Dispatch Filter
>    Affects Versions: WW 2.0-beta1
>            Reporter: Cameron Braid
>            Assignee: Patrick Lightbody

>         Attachments: ServletDispatcher-http500error.patch

>
> I suggest that the ServletDispatcher is modified using the attached patch to change the default exception handeling to be more inline with the servlet spec.
> I would like to be able to provide my own error page, and currently there is no easy way to do this.  (if any way at all?)
> I suggest that the servlet dispatched :
> a) places the exception in the request to make it availible to the error page
> b) sends a http 500 error
> Once this patch has been accepted the user can do the following:
> a) add an exception handler JSP (or any other servlet) in webl.xml
> 	<error-page>
> 		<error-code>500</error-code>
> 		<location>/WEB-INF/views/error/error.jsp</location>
> 	</error-page>
> b) create the error handler /WEB-INF/views/error/error.jsp
> <%@ page isErrorPage="true" %>
> <%@ page import="java.io.*" %>
> <h4 onclick="error.style.display='block';">Error</h4>
> <p>
> there was an unexpected error processing your request
> </p>
> <div id='error' style="display:none">
> <pre>
> <%
> if (exception != null)
> {
> 	StringWriter sw = new StringWriter();
> 	PrintWriter pw = new PrintWriter(sw);
> 	exception.printStackTrace(pw);
> 	out.print(sw);
> 	sw.close();
> 	pw.close();
> }
> %>
> </pre>
> </div>
