使用jsf进行多个CRUD的最佳策略

on my company we are developing a ERP-like app using java and jsf, so far the design team has identified about 20 entities,each with diferent properties, usually we'll be building 20 pages of CRUD , is there any better way to do this?, we are using hibernate as db access, so we came up with the idea of a single DAO for this part of the system, have you faced a similiar situation? what are your thoughts on it?on my company we are developing a ERP-like app
