Mule 3.1 - Static web server via jetty?

I cannot figure out how to use the jetty:endpoint in a Mule 3.1 context. Examples such as this question do not work in my context. The application fails to load after a long period of timeout:

It seems like the error happens when the .xsd is loaded for validation. But that is a valid URL, so I don't know what I could be doing wrong.

Any help would be appreciated.

I fixed the problem by removing the test:component element. I don't know why but its presence completely breaks the app. You can read more detailed solution instructions on my blog: http://developmentality.wordpress.com/2011/06/07/embed-a-jetty-file-server-within-mule-3-1-1/
