Two possibilities:
1. The exception that you are catching is a NullPointerException
(which has null as its message). You can check this by adding
exception.getClass().getName() to your output.
2. The exception that you are catching is not one provided by Sun
and the developer didn't set the message properly.

Subject: exception.getMessage() returns null?
Hi,
I'm trying to set up an error page, which looks like this:
%@ page isErrorPage=true %
html
headtitleSe ha producido un error/title/head
%@ include file =cabecera.jsp %
h1Se ha producido un error/h1
pEndeluego, que a ver si tenemos cuidaico, que se ha producido el
siguiente error:br
%= exception.getMessage() %
(basically cut/paste from the JSP book by Bergsten). I would
like it to
display an exception thrown from a bean, but it displays
null. What can
be the problem here? Do I need to set up something else? Besides,
exception prints just JasperException or suchlike; I would like it to
print the message I included in the RuntimeException
Thanks for any info...
J
