Hi friends,
Recently I have been asked for using JDO to do with the database in Websphere5 (I used to use Entity Beans), I have know idea what I am going to do. I knew there is a lot of JDO implementations software, but I am not sure which one is fit for websphere, by the way, does anyone know which one is for free?
Thank you very much!

Before I get struck down, I know it isn't really JDO, but we use Castor http://castor.exolab.org and have been very happy with it. A criticism of JDO is that it isn't easy to do, where Castor only took a couple of weeks to retrofit and we have it supporting WAS container managed transactions and logging etc.

Thank you David!
I will take a look at that!
By the way, have anyone used OJB and Hibernate? Which one is better? Can OJB map to an existing database?
Thanks
