Some of my questions.

• Would you recommend me with going with xDocklet. Is there any alternative for it?
• Is it one of the best way, as hbm's does get generated automatically.
• Any suggestions on the way how my Java Objects should get persisted in the DB?
• Any good tutorials over xDocklet Maven and Hibernate.

I am using xDocklet to generate HBM's automatically by annotating my POJO's.
