Here's my very simple test jsp:
<html>
<body>
<%
java.util.ResourceBundle locale_text =
java.util.ResourceBundle.getBundle("lang", new
java.util.Locale(user_locale));
%>
<%= locale_text.getString("hello") %>
</body>
</html>
As it happens, I have no resource bundles yet... so this should throw a
MissingResourceException!
Which it does. I get a org.apache.jasper.JasperException, with a root
cause of MissingResourceException.
Now I introduce the error page:
in web.xml, at the bottom, just before web-app, I have:
<error-page>
<exception-type>java.util.MissingResourceException</exception-type>
<location>/error/locale.jsp</location>
</error-page>
my error/locale.jsp is:
<html>
<body>
<h3>Language File Error</h3>
<b>Please report the following error to (email) </b>
<%
Throwable t = request.getAttribute("javax.servlet.error.exception");
%>
<%= t %>
</body>
</html>
Anyone catch the problem yet? ;)
Anyhoo.... what this will give you is *still* a Tomcat error page. But
this time it's a naked MissingResourceException (ie: no jasper exception
is wrapping it, the exception is not wrapped (unwrapped) ) (that was an
attempt to use lots of 'keywords').
The problem was that my locale.jsp was not compiling correctly (because
I failed to cast the Throwable). The error page contained an error !
I thought I'd post, just so this behaviour is documented.
duh is me. I figured it out by calling the error page directly from the
address bar.
