That $50 that I spent on the Hibernate in Action was probably the best $50 I ever spent in my life. That money paid off right away.

I had to take a legacy system which had an account system and extend that account system which required some polymorphism and a lot of tedious DB work.

Thanks to Hibernate I haven't written a single line of SQL code, DB schema was generated for me, and all I had to do was enjoy using good 'ol java beans.

Thanks guys!
