At least, I suggest you to examine sources of it and catch the ideas and approaches . Then you can try to reuse it. I know, I already have a common class which is responsible for generic tasks like update, remove and so on. But I thought it would be better to use one base class which is written by an orm and hibernate and jpa guru like gavin king (and jsf and seam of course) :-) What I not really like with the EntityHome approach ist the boundary to JSF (e.g. the automatically generated messages as result of an db operation) and the membering of the entity instance. Additionally in my base dao class I've generic list methods and I feel that the membering of the instance doesn't fit so well!
