Re: [jboss-as7-dev] UserTransaction used by remote clients

===== Regarding node-name. ===== In standalone I supposed it is the name of jboss-ejb-client.properties remote.connection.*default*.host=localhost But I have to set it by -Djboss.node.name=<>. ??? it is not possible to add a system-property to the standalone.xml for that, or do I something wrong with the system-property element in configuration??? ??? What is the name in domain mode? Is the <server name="" ...> attribute for each defined server used??? ??? Is it possible to see the node name with the management console??? The section for remote invoking EJB's note that a node name must be set unique, but I did not see any problem if I start two instances (same machine) without jboss.node.name? Is here a default created? ==== UserTransaction ===== If I do this in my client: {code} 1: UserTransaction uTx = EJBClient.getUserTransaction("Wolf"); 2: LOG.debug("UserTransaction ="+uTx); 3: uTx.begin(); 4: LOG.debug("Tx.begin() ok"); 5: bmtSession.checkTransaction(); // call a SLSB to use Tx 6: uTx.commit(); LOG.debug("Tx.commit() ok"); {code} Line 1 and 3 works nevertheless whether there is a server (with or without a correct node.name) or not. The line 5: will fail 'No EJB receiver with 'node.name' If I remove getUserTransaction I can execute the code nevertheless whether a node name is set or not. ??? So I suppose the getUTx will attach the next EJB call to that server ??? If a server is available the commit will fail (also the EJB checkTransaction show the TxState=6 (NO-Tx) java.lang.IllegalStateException: BaseTransaction.commit - ARJUNA016074: no transaction! at com.arjuna.ats.internal.jta.transaction.arjunacore.BaseTransaction.commit(BaseTransaction.java:113) at com.arjuna.ats.jbossatx.BaseTransactionManagerDelegate.commit(BaseTransactionManagerDelegate.java:75) at org.jboss.as.ejb3.remote.protocol.versionone.UserTransactionCommitTask.manageTransaction(UserTransactionCommitTask.java:47) at org.jboss.as.ejb3.remote.protocol.versionone.UserTransactionManagementTask.run(UserTransactionManagementTask.java:64) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:471) at java.util.concurrent.FutureTask$Sync.innerRun(FutureTask.java:334) at java.util.concurrent.FutureTask.run(FutureTask.java:166) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1110) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:603) at java.lang.Thread.run(Thread.java:679) at org.jboss.threads.JBossThread.run(JBossThread.java:122) ??? My question what is wrong with my assumption or code??? - Wolf On 03/06/2012 06:28 PM, David M.
