Description copied from interface: RequestExceptionHandler

Reponsible for handling the error in some way and providing some response to the client. A default implementation may render an error response page.

The handler is also responsible for setting the response status and the X-Tapestry-ErrorMessage response header. These are very important in Ajax requests to allow the client-side logic to detect the error and present it to the user.

Specified by:

handleRequestException in interface RequestExceptionHandler

Parameters:

exception - uncaught exception to be reported

Throws:

java.io.IOException
