singleton

its out of question that a dao will not hold any state.

however, for easiest access to the class, is it better to use prototype( = new every time) or singleton?

simple object creation is cheap for dao's.. it typically only holds a sessionfactory, accessing the object from a list of singletons may be equally expensive.

clarfication: the focus of this question is, if there is a common convention to the scoping of daos.
