Hi everybody,
Whenever I follow the Error Page Recipe [1] to create custom a error
response page, everything works fine except that, to my knowledge, the
page can only have a fixed message. For example, my 403 error page
always says "Sorry, you can't have that". That's fine, but what if I
want my error pages to display the more specific underlying message?
For example, the Java class for one of my app's regular pages has the
following within an onActivate() method:
return new HttpError(500, "The database just blew up");
which generates the proper 500 response to the container. Now, if I
have NOT configured a custom error response for status 500 in my
web.xml then my servlet container (Jetty, currently) dutifully
displays the specific message (the "reason") that was given:
HTTP ERROR 500
Problem accessing /foo. Reason:
The database just blew up
But I would really like to make the text of that 3rd line ("The
database just blew up") visible within my (Tapestry) custom error
page. Is there any way to get it? I tried injecting the Response
object but it doesn't seem to contain anything I can use for this. I
could copy the message to the session before calling return new
HttpError(....) but -- yuk.
Thanks!
