Hi Tim! I think I have the same issue. I am using 2 instances of jboss 4.2.1GA with messaging 1.3 The source is a remote server (on my local machine). | <mbean code="org.jboss.jms.jndi.JMSProviderLoader" name="jboss.messaging:service=JMSProviderLoaderRemote,name=RemoteJMSProvider_A"> | <attribute name="ProviderName">RemoteJMSProvider_A</attribute> | <attribute name="ProviderAdapterClass">org.jboss.jms.jndi.JNDIProviderAdapter</attribute> | <!-- The combined connection factory --> | <attribute name="FactoryRef">XAConnectionFactory</attribute> | <!-- The queue connection factory --> | <attribute name="QueueFactoryRef">XAConnectionFactory</attribute> | <!-- The topic factory --> | <attribute name="TopicFactoryRef">XAConnectionFactory</attribute> | <attribute name="Properties"> | java.naming.factory.initial=org.jnp.interfaces.NamingContextFactory | java.naming.factory.url.pkgs=org.jnp.interfaces | java.naming.provider.url=localhost:2099 | </attribute> | </mbean> | As you can see I am not using "java:" but the error is the same. My error only occurs if I am using "QOS_ONCE_AND_ONLY_ONCE". Settings to 1 works. On the source I get: | 14:04:59,328 ERROR [ExceptionUtil] ConnectionEndpoint[76] sendTransaction [a42z4q-jbavvr-f5z5x8i7-1-f5z7mkao-3l] | javax.jms.JMSException: Failed to route Reference[8]:RELIABLE to incomingSyncRequests | at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.sendMessage(ServerConnectionEndpoint.java:694) | at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.processTransaction(ServerConnectionEndpoint.java:786) | at org.jboss.jms.server.endpoint.ServerConnectionEndpoint.sendTransaction(ServerConnectionEndpoint.java:456) | at org.jboss.jms.server.endpoint.advised.ConnectionAdvised.org$jboss$jms$server$endpoint$advised$ConnectionAdvised$sendTransaction$aop(ConnectionAdvised.java:101) | at org.jboss.jms.server.endpoint.advised.ConnectionAdvised$sendTransaction_N3268650789275322226.invokeNext(ConnectionAdvised$sendTransaction_N3268650789275322226.java) | at org.jboss.jms.server.container.ServerLogInterceptor.invoke(ServerLogInterceptor.java:105) | at org.jboss.jms.server.endpoint.advised.ConnectionAdvised$sendTransaction_N3268650789275322226.invokeNext(ConnectionAdvised$sendTransaction_N3268650789275322226.java) | at org.jboss.jms.server.endpoint.advised.ConnectionAdvised.sendTransaction(ConnectionAdvised.java) | at org.jboss.jms.wireformat.ConnectionSendTransactionRequest.serverInvoke(ConnectionSendTransactionRequest.java:82) | at org.jboss.jms.server.remoting.JMSServerInvocationHandler.invoke(JMSServerInvocationHandler.java:141) | at org.jboss.remoting.ServerInvoker.invoke(ServerInvoker.java:734) | at org.jboss.remoting.transport.socket.ServerThread.processInvocation(ServerThread.java:560) | at org.jboss.remoting.transport.socket.ServerThread.dorun(ServerThread.java:383) | at org.jboss.remoting.transport.socket.ServerThread.run(ServerThread.java:165) | On my destination (where bridging is installed) I get: | 14:04:59,328 WARN [Bridge] Failed to send + acknowledge batch, closing JMS objects | javax.transaction.RollbackException: [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] [com.arjuna.ats.internal.jta.transaction.arjunacore.commitwhenaborted] Can't commit because the transaction is in aborted state | at com.arjuna.ats.internal.jta.transaction.arjunacore.TransactionImple.commit(TransactionImple.java:253) | at org.jboss.jms.server.bridge.Bridge.sendBatch(Bridge.java:1221) | at org.jboss.jms.server.bridge.Bridge.access$1600(Bridge.java:59) | at org.jboss.jms.server.bridge.Bridge$BatchTimeChecker.run(Bridge.java:1336) | at java.lang.Thread.run(Thread.java:619) | 14:04:59,359 ERROR [ClosedInterceptor] ClosedInterceptor.ClientSessionDelegate[77]: method getXAResource() did not go through, the interceptor is CLOSED | 14:04:59,359 WARN [Bridge] Will retry after a pause of 50000 ms | Any Ideas?
