Mule 3.3.0 Jdbc Transaction Undesired Commit

Question

I'm trying to setup a dummy example of jdbc transaction to test commit and rollback. Here I've got :

• an http entrypoint to start flow,
• an insert on db a component that throw and exception
• an update on db.

I expect that after component exception insert were rollback but it doesn't. Debugging mule source I've seen that in class BeginAndResolveTransactionInterceptor the insert statement terminate with a commit because resolveStartedTransaction property is set to true. This is why in default-exception-strategy rollback doesn't work I suppose... I don't know if I'm doing something wrong in configuration or if is a wrong behavior.

Answer 1

ok I've found a workaround. If transaction is started by vm instead of jdbc it works fine. Probably there is a bug in jdbc/transaction that make commit always when first transactional endpoint is jdbc.
