Is it possible to lookup and use UserTransaction from a remote-client as in AS5? Or is it planned for further release?

Another interesting thing you can also do is use Arjuna in Jta mode on the client and join local resources in the transaction as well.

===== 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) ???

But with BMT-SLSB. If I start the Tx at client and call a method the following code return with FALSE: {code} @Stateless @TransactionManagement(TransactionManagementType.BEAN) public class BMTStatelessSessionBean implements BMTStatelessSession { private static final Logger LOGGER = LoggerFactory.getLogger(BMTStatelessSessionBean.class); @Resource UserTransaction uTx; @Override public boolean checkTransaction() { try { if(uTx.getStatus() == Status.STATUS_ACTIVE) { return true; } LOGGER.error("Transaction is not Active as expected! State {}",uTx.getStatus()); } catch (SystemException e) { LOGGER.error("Could not check Transaction!",e); } return false; } {code} Am I wrong? If I remember correct from my examples this should work in AS5. Or is it a bug?

@Jaikiran - might be a question for you What about loadbalancing EJB calls? If I remember rightly this was planned for 7.1.1.
