An ORM Standard: EJB and JDO cooperating?!
Dion mentioned this might happen: Happy Harmony for EJB3 & JDO. This is very cool IMO - and I hope it works out. I'd love to see a standard way to map POJOs to databases. The best part is both camps hope to move quickly on this.
The technical objective for this new POJO persistence model is to provide a single object/relational mapping facility for all Java application developers that works in both J2SE and J2EE. The work will be done within the J2EE 5.0 time frame.

JDOQL and EQL are not as good as ANSI SQL on a DB engine. People will get better use out of JDBC as DAO then EJB as DAO. I a Celko Book, SQL for Smarties... not one of those tekniques works with EQL.
98% of time you do not need transaction more than DB commit/rollback
Petstore is a vampire, keeps coming back. There are better DAO's. iBatis PetStore is now Apache, that is a good example
.NET is better than EJB. DAO is better than .NET.
JCP has enough vendors showing of technology. They need users so that they solve problems we have - not technology looking for a problem. Like ... why would I EJB for muti row CRUD when I have alternatives.
Users show file a lawsuit against vendors that lie if the vendor promises that EJB is fast an simple, and if then EJB's ad to project complexity.
"goal of programing is to control complexity" - K&R!
Enough w/ the elephats.
