    ClassCastException

    Eric Härtel Newbie

      Hi forum,


      today I started with Seam and felt directly into a problem. I started with a fresh and new JBoss (jboss-5.0.1.GA) and the registration example, as recommended in the tutorial. After the first deployment the application worked well, but after the second deploy I got a wired exception:


      DEPLOYMENTS IN ERROR:
        Deployment "vfsfile:/home/eric/Programme/jboss-5.0.1.GA/server/default/deploy/jboss-seam-registration.ear/" is in error due to the following reason(s): java.lang.ClassCastException: org.jboss.metadata.ear.spec.EjbModuleMetaData cannot be cast to org.jboss.metadata.ear.spec.WebModuleMetaData

      Until now I didn't change anything in the code or configuration. Any sugestions or hint to isolate the problem?


      Greetings
