Subject [jira] Commented: (DERBY-2360) The XAResource.end(xid, XAResource.TMFAIL) throws an exception
Date Wed, 21 Feb 2007 13:21:05 GMT

    [ https://issues.apache.org/jira/browse/DERBY-2360?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#action_12474694
] 

Julius Stroffek commented on DERBY-2360:
----------------------------------------

I checked the Apache Geronimo (http://geronimo.apache.org/) and the implementation code for
javax.transaction.Transaction.delistResource looks as (in a class org.apache.geronimo.transaction.manager.TransactionImpl)

        try {
            xaRes.end(manager.getBranchId(), flag);
            if (flag == XAResource.TMSUSPEND) {
                suspendedXaResources.put(xaRes, manager);
            }
            return true;
        } catch (XAException e) {
            log.warn("Unable to delist XAResource " + xaRes + ", error code: " + e.errorCode,
e);
            return false;
        }
 
So, If I will pass a TMFAIL in flags I will get an exception that the transaction manager
is not able to delist the resource.

I also checked JOTM on ObjectWeb (http://jotm.objectweb.org/) and the corresponding code for
javax.transaction.Transaction.delistResource which can be found in org.objectweb.jotm.TranasctionImpl.java
is

        // Send the XA end to the XAResource
        try {
            xares.end (myjavaxxid, flag);
            // xares.end( (javax.transaction.xa.Xid) resXid, flag );
        } catch (XAException e) {
            String error =
                "Cannot send XA end:"
                    + e
                    + " (error code = "
                    + e.errorCode
                    + ") --"
                    + e.getMessage();
            TraceTm.jotm.error(error);
            if (TraceTm.jta.isDebugEnabled()) {
                TraceTm.jotm.debug("xares.end= " + xares);
            }
            throw new SystemException(error);
        }

which also propagates the exception thrown in XAResource.end with TMFAIL flag as an error
to the application.

same as with TMSUCCESS except that I can only rollback the transaction.
