Prevent enlisting additional resources on EJB caller side in case of server side @RequiresNew --------------------------------------------------------------------------------------------- Key: WFLY-10258 URL: https://issues.jboss.org/browse/WFLY-10258 Project: WildFly Issue Type: Bug Components: EJB Affects Versions: 12.0.0.Final Reporter: Jörg Bäsner Scenario: - server-1 (intermediary) -- Running standalone profile -- Has a remote-outbound-connection pointing at server-2 through server-2's public IP address -- Intermediary bean need to lookup the Target bean in server-2 and also inject the {{TransactionManager}} -- Intermediary bean need to enlist a _dummy_ XAResource - server-2 (target) -- disable {{JBOSS-LOCAL-USER}} auth -- Target bean needs to be annotated with {{@REQUIRES_NEW}} (important) - Standalone EJB client invokes an intermediary bean server-1, which as a result invokes target bean on server-2. The _dummy_ XAResource should log in the {{commit}} method whether one-phase optimization is being used like: {code} @Override public void commit(Xid arg0, boolean onePhaseOptim) throws XAException { logger.info("-- Committing in the client resource. One-phase optimisation is: " + onePhaseOptim + " --" + (onePhaseOptim ? "" : " -> TWO-PHASE COMMIT !!!")); } {code} In this scenario it is expected that the one-phase optimization is being used!
