Maybe someone would be interested in a library (framework?) I've developed last time with JBossAOP.
It's kind of persistance concern which uses Prevayler: object, in-memory database.
From the top of it you code POJOs only, and annotate root of your object graph with @@pat.root and every method you want to be transacted with @@pat.transaction (and every business class with @@pat.bo).
I like the "AOP metadata" way. There are some features from JBossAOP I still need, but .. not all at once.
So, anyway: thanks for nice AOP library guys :)
