what is your suggestion to use DTOs and still use container managed transactions?
Any hints appreciated,
DTO'S are just data holders. The standard pattern is to pass a dto to a a session bean which does an insert or update using data from the dto. Using cmt allows multiple session beans/dao's to be strung together in a single transaction
Probably I need to be more specific.
I'm working on a program the uses session beans as a facade, and DTOs to allow for bulk data transfer. So the question(s) could be more detailed:
1. How do you control the transactions on the domain entities when using session beans as facade ?
2. How do you keep transactions open etc. when using DTOs ? The entitiy bean objects may already be back in the pool, although the DTOs are in-use at the client. How do you synchronize the DTOs with the entity beans ? How do you open transactions for changing their data, or even delete the table rows ? etc. pp.
