I am using seam 2 and sun app server 9. I have two seemingly identical configurations. On one version my ear works fine and on the other I get this exception whenever any seam @Name object is referenced i.e. even if I remove the authentication.

javax.el.PropertyNotFoundException: Target Unreachable, identifier 'authenticator' resolved to null

 I am fairly sure seam is initing correctly as as I can see the following in the logs.

I have the web.xml completed correctly and as I said it works on my home setup which I beleive to be identical regards the java development environment.

Thanks for any help I have been stuck with this for two days now.
