Hi,
 
You will find a full copy of the **default** web.xml in TOMCAT_HOME/conf/.
 
What is the default web.xml --> Extract from the user guide (which you will
find at TOMCAT_HOME\doc\uguide\tomcat_ug.html: recommended reading)
[A detailed description of web.xml and the web application structure
(including directory structure and configuration) is available in chapters
9, 10 and 14 of the  <http://java.sun.com/products/servlet/> Servlet API
Spec and we are not going to write about it. 

There is however a small Tomcat related "feature" that is related to
web.xml. Tomcat lets the user define default web.xml values for all context
by putting a default web.xml file in the conf directory. When constructing a
new Context, Tomcat uses the default web.xml file as the base configuration
and the application specific web.xml (the one located in the application's
WEB-INF/web.xml), only overwrite these defaults.]

So if you want the error pages to apply to all webapps then you put the
error page tags in the default web.xml like this:

<?xml version="1.0" encoding="ISO-8859-1"?>

<!DOCTYPE web-app

PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"

"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

<web-app>

<!-- IMPORTANT: all the tags that were already in the default web.xml file
should remain in the file -->
 
<error-page>
<exception-type>javax.servlet.TryagainException</exception-type>
<location>/errors/TryAgain.html</location>
</error-page>
 
<error-page>
<error-code>503</error-code>
<location>/errors/TryAgain.html</location>
</error-page>

</web-app>

(I assume that you have renamed the directories and files accordingly:
errors directory and TryAgain.html file are only examples).

If you only want the error pages to apply to a particular webapp then you
should create a web.xml file that you place in
TOMCAT_HOME/webapps/yourWebApp/WEB-INF. This file should look like this:

<!DOCTYPE web-app

PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.2//EN"

"http://java.sun.com/j2ee/dtds/web-app_2_2.dtd">

<web-app>

<error-page>
<exception-type>javax.servlet.TryagainException</exception-type>
<location>/errors/TryAgain.html</location>
</error-page>
 
<error-page>
<error-code>503</error-code>
<location>/errors/TryAgain.html</location>
</error-page>

</web-app>

I hope this works.

it didn´t work...could you please give a "complete" web.xml? and where
should I put this file? in %TOMCAT_HOME%/conf or somewhere else? I´m using
tomcat 3.2.2 and win2k, I would like any help you could provide, because I
just started working with tomcat.
 
thanks,

Hi,
 
Using <error-page> elements in the web.xml, you can program web applications
to handle HTTP errors and exceptions.
 
The deployment description below makes the container send the
/errors/TryAgain.html file if either a TryAgainExeption or the
HttpServletResponse.SC_SERVER_UNAVAILABLE error code occurs:
 
<web-app>
 
<!-- Servlet definitions -->
 
<error-page>
<exception-type>javax.servlet.TryagainException</exception-type>
<location>/errors/TryAgain.html</location>
</error-page>
 
<error-page>
<error-code>503</error-code>

<location>/errors/TryAgain.html</location>
</error-page>
 
I hope this helps.
