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 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 defaultw eb.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.

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.
