Access Response.sendError() method's argument from JSP

Question

If I send a HTTP status code and a message like

response.sendError(404, "message here");

how do I reference the message from the associated, error-handling JSP (marked w/ isErroPage=true)?

None of these approaches work:

• ${pageContext.errorData.throwable.message}
• How to get the message in a custom error page (Tomcat)?
