    Could not instantiate Seam component: citiesHome

    Onur  Uysal Newbie

      Hi All,


      I've Installed Seam 2.2.1 working on JBoss 5.0.1. The core classes (login.java) which comes with seam works properly... But if i add new entity to my project, I'm getting some errors when i deploy.

                Did you put *-ds.xml file with datasources configuration to your deploy folder?

                see for example "server\default\deploy\hsqldb-ds.xml"  file.
