What is t= he default=20 web.xml --> Extract from the user guide (which you will find at=20 TOMCAT_HOME\doc\uguide\tomcat_ug.html: recommended reading)

[<= /FONT>A detailed descripti= on of=20 web.xml and the web application structure (including directory structure an= d=20 configuration) is available in chapters 9, 10 and 14 of the = Servlet API=20 Spec and we are not going to write a= bout it.=20

There is however a small Tomcat relate= d=20 "feature" that is related to web.xml. Tomcat lets the user define default= w eb.xml values for all context by putting a default web.xml file in the con= f=20 directory. When constructing a new Context, Tomcat uses the default web.xml= file=20 as the base configuration and the application specific web.xml (the one loc= ated=20 in the application's WEB-INF/web.xml), only overwrite these defaults.]

So if= you want=20 the error pages to apply to all webapps then you put the error page tags in= the=20 default web.xml like this:

<?xml version=3D"1.0" encoding=3D"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>

<error-page>

<exception-type>javax.servlet.TryagainException</exception-type>

<location>/errors/TryAgain.html</location>

</error-page>

<error-page>

<error-code>503</error-code><= /DIV>

<location>/errors/TryAgain.html</location>

</error-page>

</web-app>

(I as= sume that=20 you have renamed the directories and files accordingly: errors directory an= d=20 TryAgain.html file are only examples).

If yo= u only want=20 the error pages to apply to a particular webapp then you should create a we= b.xml=20 file that you place in TOMCAT_HOME/webapps/yourWebApp/WEB-INF. This file sh= ould=20 look like this:

<!= DOCTYPE=20 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><= /DIV>

<location>/errors/TryAgain.html</location>

</error-page>

</web-app>

I hop= e this=20 works.

Hi,

Using= <error-page> elements in the web.xml, you can program web applica= tions=20 to handle HTTP errors and exceptions.

The d= eployment=20 description below makes the container send the /errors/TryAgain.html fi= le if=20 either a TryAgainExeption or the HttpServletResponse.SC_SERVER_UNAVAILA= BLE=20 error code occurs:

<web-app>

<!= -- Servlet=20 definitions -->

<error-page>

<exception-type>javax.servlet.Tryagain= Exception</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.
