Transaction Attribute & Rollback Question

[michael schufer]

Hi,

If I have a session bean (A) calling 3 other methods in 3 other diffent session beans (B,C,D)
as follows with the transaction attributes:


A ---> B (Create, Transaction Attribute: Required)
---> C (Query, Transaction Attribute: Never)
---> D (Delete, Transaction Attribute: Required)

Question: If there's a failure in Sesssion Bean D, will the whole transaction be roll backed to B? Assuming that the context.setRollBackOnly method is being called in each of the catch method.
Thanks.

I assume there is no transaction in A, otherwise A'll get an RemoteException calling C.

A calls B. B starts a transaction, say Tx-B, and completes (commit).
A calls C.
A calls D. D starts a transaction, say Tx-D, and rollbacks. This will cause only Tx-D to rollback, not Tx-B.

J2EE does not support nested transactions. If you want Tx-B to rollback as well, then you need to use "Required" in A and change "Never" to "NotSupported" in C.
