i've seen this error before when i use @EJB, but don't actually invoke any 
methods on the injected instance.

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

[xinhua]

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?
