Nested/Sub Transaction in service Mix
Hello,
Can anyone let me know is there support of Nested or sub
transaction in servicemix. What iam looking for if a msg is exchanged
between A->B->C , the flow between A->C is the main transaction and the flow
between B->C is the subtransction. So if exchange between B->C fails then
the flow between A->B is considered as a failure and it should be rolled
back.
Information about any third party component which can be deployed in
servicemix to handle the nexted/sub transaction is also welcome.
looking for reply
Thanks and Regards
Param

The component starting the transaction is responsible for the commit
or rollback. This happens when the component receives the response
from the provider.
Atm, the only JBI endpoint able to start transactions is the JMS one.
You need to specify transacted="xa" and synchronous="true" to have the
transaction being conveyed to other components in the flow. All other
components will be enlisted in the transaction and when the whole flow
completes, the jms endpoint will commit or rollback the transaction (a
rollback will occcur if the exchange has an ERROR status).

Hello gnodet,
do you have any sample code or link about explaining this concept. How
do we say in component c that the transaction is started by A and which
component does the rollback?.. A sample code will really help me out to
understand better.

Why would you need subtransactions for that, you just need a single
transaction and if any error occurs, the whole transaction will be
rolled back.
