It didn't work. I got a 500 later in my code. Here's what I did:
if(detail.size() > 0)
{
dbutil = new
DBUtil(getServletConfig().getInitParameter(Constants.JNDI_NAME));
dbutil.executeNoResults(updateSql);
dbutil.cleanup();
session.setAttribute("title", title);
session.setAttribute("desc", title);
session.setAttribute("keywords", keywords);
dispatcher =
getServletContext().getRequestDispatcher("/displayArticle.jsp");
}
else
response.sendError(404, "");
// dispatcher = getServletContext().getRequestDispatcher("/404.jsp");
Notice I commented out the code that would later dispatch to 404.jsp.
Here's my entry from web.xml:
</error-page>
<error-page>
<error-code>404</error-code>
<location>/404.jsp</location>
</error-page>
Looks like the 404 page isn't being invoked by the response.sendError(404, "");

Servlet docs suggest you can nominate your JSP as an
error page for status 404 - in Tomcat you could put
this in conf/web.xml (after <welcome-file-list>)
<error-page>
<error-code>404</error-code>
<location>/my_error_404.jsp</location>
</error-page>
then if you call response.sendError(404, "") when your
app decides the request isn't sensible, this page will
be used. I haven't tried this.
