Subject Re: Cayenne pattern quesiton

Also I suspect I am not using a classic version of DAO. My DAO's are  
morphed with the "business layer" and can have interactions with other  
subsystems, not just Cayenne (e.g. caching, data access via web  
services, etc.). Also they are not auto-generated, as any new methods  
are created when a need in them arises in the application. The idea is  
to keep it tight and avoid having any unused and unneeded methods.
