[jboss-user] [EJB 3.0] - Re: Need Help! encounter strange Exception:not used by any E

Hi, i use DAO pattern, all CRUD fuctions are supposed come from GenericDAO for example, in GenericDAO i defined findAll(), findById()....then , i let EmailTemplate extends GenericDAO to get such frequently used functions and these crud functions are also INVOKED in my SLSB. If the reason of this exception is i did not defined any method in my DAO session Bean, please tell me what is the pupose of this Exception, against inheritance in EJB3 world?
