Subject: Persistence with JDBC ??? 2005-10-11 - By J=?ISO-8859-1?Q?=F8rn_=D8lmheim?=

Hi Juan.
We were in the same place you are now about five years ago. We had an old
legacy system filled with PL/SQL logic that we wanted to move to J2EE. We
started out trying to reuse the database as much as possible, and tried to
build our home-grown JDBC based persistence framework to do this. This has
not been successful.
Over the last five years, our knowledge of J2EE has evolved, and our plans
have changed accordingly. I see that you're not using EJBs, and this is
good. We started out using lots of them, but now its all SPRING. We've also
used the practices of Eric Evans Domain Driven Design to build rich domain
models for our business logic to replace the old PL/SQL code. This turns out
to be a lot more maintainable and faster too. We use JDO with a clean
database to store the domain model.
I really think this is the way to go, as we've been trying all the different
steps in between over the course of the last five years.
Best regards,
J?rn ?lmheim
