ReaperMonitor usage

[hernanbolido]

Hi!

I'm trying to implement a listener implementing the ReaperMonitor interface, but I can't find the way to stablish the relation between the monitor an the TransactionReaper instance.

can anyone give me a piece of advice about this?

Regards.

Hernán.

Hi Hernan,

Thanks for your interest in Narayana

Hope this helps: https://github.com/jbosstm/narayana/blob/master/ArjunaCore/arjuna/tests/classes/com/hp/mwtests/ts/arjuna/reaper/ReaperMonitorTest.java

Thanks,

Hi Tom! Thank you very much!

I'm wondering if this mechanism can be used for wildfly's subsystem too, or it's only for standalone instantiation.

Hi Hernan,

You should be OK to use it in WFLY but I haven't tried myself:

import com.arjuna.ats.arjuna.coordinator.TransactionReaper;

import com.arjuna.ats.arjuna.coordinator.listener.ReaperMonitor;

TransactionReaper reaper = TransactionReaper.transactionReaper();

reaper.addListener(new ReaperMonitor() {...});

Don't include the Narayana jar in your .war/ear, instead you need something like this in your manifest:

Dependencies: org.jboss.jts

Please note that the ReaperMonitor is called after the transaction is rolled back/set rollback only. It may have an impact on the implementation of your listener.

Hope it helps,

Tom
