Subject ComponentSelector could not find the component Error
Date Tue, 29 Nov 2005 23:38:50 GMT
Hello,
    I am relatively new with Cocoon and have been going through the book 
"Cocoon Developer's handbook" by Lajos Moczar and Jeremy aston.  The book 
goes through an example of a website that a business might use.  I am trying 
to add authentication to this website by adding an xsp page called login.xsp 
and an html page called login.html.  I am running Cocoon with apache tomcat 
4.0 and am using cocoon 2.0.4, on windows xp.  When I try to display the 
page login.html I get a fatal error that looks like the following:

type fatal

message UnnamedSelector: ComponentSelector could not find the component for 
hint [resources]

description org.apache.avalon.framework.component.ComponentException: 
UnnamedSelector: ComponentSelector could not find the component for hint 
[resources]

I don't know where exactly to look to fix this.  If anyone could give me a 
place to look I would appreciate it.  Below I have the files that I am 
using.

Thanks for your time,
