    Deployment problem with a simple EJB example

    Andreas Meisel Newbie

      Hi,
      I want to reproduce an EJB tutorial and want to deploy Konto.jar into JBoss 4.0.0. So, I put it into the default/deploy directoy and I got the following error message:

      13:29:33,581 WARN [verifier] EJB spec violation:
      Bean : KontoBean
      Method : public abstract double abheben(int) throws RemoteException
      Section: 6.10.5
      Warning: The methods defined in the remote interface must have a matching method
      in the bean's class with the same name and same number and types of arguments.

      13:29:33,591 WARN [verifier] EJB spec violation:
      Bean : KontoBean
      Method : public abstract void einzahlen(int) throws RemoteException
      Section: 6.10.5
      Warning: The methods defined in the remote interface must have a matching method
      in the bean's class with the same name and same number and types of arguments.
