Deployment problem with a simple EJB example
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.
