The class must implement the bean�s business interface(s) or the methods of the bean�s business interface(s), if any.
So your bean class should implement both the methods in the interface.
i am implementing(definition) only one in the bean class but i am not getting any error.
Where are you checking the error for? Are you looking in a IDE or are you checking during deployment of the beans on the server? And does your bean class "implement" the business interface or are you using annotations or deployment descriptor to specify the business interface for the bean?
