See the above two post by Jacob and tynor, they have the solution. But you will also need it defined on your local interface for the SFSB. The reason the @DataModel works is because you are referring to it directly as a Seam component. It is NOT a method. All public methods of Seam components (ie your stateful and stateless beans) need to be declared in local interfaces. This is required by Seam (and by the EJB spec) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4090839#...
