To view the discussion, visit: https://community.jboss.org/message/747682#747682 -------------------------------------------------------------- Hi all, I have a connector based on JCA. I am confused on the inflow transaction issue. I construct a XID and submit the work to work manager. The work will access the same database twice, and they will use 2 XAResources. I configured that all XAResource are not belong to same RM. The first XAResource can work fine, but the second XAResource will *use the same XID* to start, it is failed. I noticed that the TransactionImple will use com.arjuna.ats.internal.jta.transaction.arjunacore.subordinate.jca.TransactionImple, its createXid method will use the below code, it will use the old one. I want to confirm that JCA subordinator can only include one XAResource? If it is no, how can I do it?     private final Xid createXid(boolean branch, XAModifier theModifier)     {         Xid xid = baseXid();           if (xid != null)             return xid;           xid = new XidImple(_theTransaction, branch);           if (theModifier != null)         {             try             {                 xid = theModifier.createXid((XidImple) xid);             }             catch (Exception e)             {                 e.printStackTrace();             }         }           return xid;     } public final Xid baseXid () {     return ((SubordinateAtomicAction) _theTransaction).getXid(); } It's my start transaction code snippet. ResourceAdapterImpl ra = (ResourceAdapterImpl)notifier_.getResourceAdapter(); BootstrapContext ctx = ra.getContext(); Xid xid = getXid(tid); WorkManager workMgr = ctx.getWorkManager(); ExecutionContext ectx = new ExecutionContext(); ectx.setXid(xid); MyWork work = new MyWork(this, events); workMgr.doWork(work, WorkManager.INDEFINITE, ectx, work); I use JBossTS 4.2.3 SP5 C09. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/747682#747682] Start a new discussion in IronJacamar at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&...]
