I'm using WAS 5 and a UserTransaction.
As I told in my answer to Mickael, I used a different instance of Database for each database operation :(
I'm coding a facade over Castor in a J2EE context and I'm looking for some advice on how to do it correctly.
cf. my answer to Mickael:

Cedrick,
What J2EE container are you using? What transaction type is being used?
