This can be done in a Filter. Horribly pseudo coded as:
doFilter(...) {
if (null==servletContext.getResource(request.getServletPath())) {
throw new ServletException("No file");
}
chain.doFilter(...);
}
Then map the filter as needed (with any additional checks too)

Hi all,
I am a Tiles developer and I am struggling to resolve a problem in
Tiles, that is reflected from a "gap" in the servlet specifications:
https://issues.apache.org/struts/browse/TILES-320
What I want to do is to throw an exception whenever an included
(through the use of RequestDispatcher.include and PageContext.include)
resource is missing.
The problem is that RequestDispatcher.include and PageContext.include
do not throw anything if a resource is missing, they simple "go on"
rendering the page. The API specification does not say anything about
it:
http://java.sun.com/javaee/5/docs/api/javax/servlet/RequestDispatcher.html#include(javax.servlet.ServletRequest,%20javax.servlet.ServletResponse)
http://java.sun.com/javaee/5/docs/api/javax/servlet/jsp/PageContext.html#include(java.lang.String)
