Problem with the Sample Ajax Echo Project

[benek]

I'm new in JSF and Richfaces, and I am trying to follow the 'Getting Starded With Richfaces' guide: http://www.jboss.org/file-access/default/members/jbossrichfaces/freezone/docs/devguide/en/html_single/index.html#GettingStarted

This is the code of my JSP:

When I start the application server (glassfish) and go to http://localhost:8080/PruebaRichfaces/ then the page looks like this:

http://farm4.static.flickr.com/3147/2435668342_91f38b4b1a_o.jpg

And my application server log show this error:

Error on send resource
org.ajax4jsf.cache.CacheException: Could not get Input stream for resource: org.ajax4jsf.javascript.AjaxScript

The complete exception trace is here:

Does anyone knows what is happening?
