Re: about implement "folder" with nanning-aop

I am feel well that i am on the right track. in
the old days i do not sure it can do like it or not.

We have no plan to using this in current projects,
every one is newbie to AOP, they more likely to using
oracle, ejb than prevayler, nanning etc. I think it is
a innovation and will take a long time. 

BTW, i will end current job in this weekend and start
seeking for a new job, i hope i can do more aop and 
nanning development in late new job. Currently, just
for me, "Good Good Study, Day Day Up"
(好好学习，
天天向上） , :-)
