Seam 2.1.1 + Jetty 6

[orangeven]

i am trying to make a simple seam(2.1.1) project runing in the Jetty 6 since several weeks. i got many exceptions so that i am almost despair. is that possible? hat somebody already try it?      
I am grateful if someone give me a hint.

i have found something:
- howto add Embedded JBoss to Tomcat: http://www.jboss.org/community/docs/DOC-9687
   but there is nothing for jetty.
- a discus: http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4093683#4093683
   and a blog artikel: http://www.jroller.com/wesleyhales/entry/my_first_seam_2_0
   both said, seam2 app. can't run on jetty.

is that true? had someone already try this?

thanks
