You could use a JSP error page from a servlet.
Catch any ServletException errors, and do a redirect to your JSP error page.
Here's short snips from one of my servlets:
try {
//sending email from the servlet...
} catch (ServletException ex) {
log("Failure to send email", ex);
sendErrorRedirect(req, res, "/error.jsp", ex);
}
protected void sendErrorRedirect(HttpServletRequest request,
HttpServletResponse response, String errorPageURL, Throwable e) {
try {
request.setAttribute ("javax.servlet.jsp.jspException", e);
getServletConfig().getServletContext().getRequestDispatcher(errorPageURL).fo
rward(request, response);
} catch (Exception ex) {
log(getServletName() + ".sendErrorRedirect ", ex);
}
}
Hope that helps...

Subject: Change the default error message
Hello all,
This is the first time I write to this page, and I send a salutation to all
people.
Well, this is my question. I have installed jakarta tomcat 3.2.2 in a linux
machine. All works fine but I want change one thing and I don't know how
can I make it. When occurs some error in a servlet, the servlet engine
sends a response like this:
Error: 500
Localizacion: /examples/servlet/EnbreveServlet
Error interno del servlet:
java.lang.NullPointerException

Can I change this information to a default html page?
Thanks.
PS: Could be this is a FAQ, but I have searching in the FAQ-o-matic and in
the archive list and I can't find answer to my question.
