public interface Trader
extends EJBObject
The methods in this interface are the public face of TraderBean. The signatures of the methods are identical to those of the EJBean, except that these methods throw a java.rmi.RemoteException. Note that the EJBean does not implement this interface. The corresponding code-generated EJBObject, TraderBeanE, implements this interface and delegates to the bean.
