[commons-chain] catalog not being set

[Filipe Tavares <ft...@devyant.org>]

Hello,

    I'm trying to use commons-chain on my Struts web app. For what I've 
seen on the log, the ChainListener is loading and catalog.xml is 
correctly loaded. Now, the problem is that the catalog instance isn't 
where it should be. This meaning that:

    Catalog catalog = (Catalog) request.getSession() 
.getServletContext().getAttribute("catalog");

returns null, for there is no such attribute.

*my catalog.xml:*
<?xml version="1.0" ?>
<chains>
    <command
        name="Test"
        className="org.devyant.www.commands.Test" />
</chains>


*my web.xml:*
<?xml version="1.0" encoding="ISO-8859-1"?>
<web-app xmlns="http://java.sun.com/xml/ns/j2ee"
    xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
    xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd"
    version="2.4">
