[jboss-user] [JBoss Seam] - Problem reading components

[jimcarrey]

Hi,
I am using tomcat with the embeddable EJB container.
At startup, after seam initialises it's own components and tries to initialise the application components, I get the following error:

I am the SeamListener configured in my web.xml and the version of seam I am using is, Seam-Version: 1.0.0.CR3.

any ideas appreciated?
