Hi,
can someone give me some advice on how to run seam 2.0.0 beta1 on Jetty.

I'm currently trying to run it using the maven jetty plugin and get the following exception on each request:

Found a wiki page [1] with details about getting seam running on tomcat, and I wonder if there are similar techniques for jetty.

Many thanks,
