[EJB 3.0] New message: "Re: Entity Manager with BMT and Transaction Timeout"

by Alexander Hartner

User development, A new message was posted in the thread "Entity Manager with BMT and Transaction Timeout": http://community.jboss.org/message/528562#528562 Author : Alexander Hartner Profile : http://community.jboss.org/people/ejb3workshop Message: -------------------------------------------------------------- Thanks for responsing. Here is my bean code. First the MDB which shows the injection of an entityManager, usertransaction and a datasource: > ... > @MessageDriven(name = "WorkListener", activationConfig = { > @ActivationConfigProperty(propertyName = "acknowledgeMode", propertyValue = "Auto-acknowledge"), > @ActivationConfigProperty(propertyName = "destinationType", propertyValue = "javax.jms.Queue"), > @ActivationConfigProperty(propertyName = "destination", propertyValue = "queue/abc/WorkMessages") > }) > @TransactionManagement(TransactionManagementType.BEAN) > public class WorkListener implements MessageListener { > > @PersistenceContext(unitName = "entityManager") > protected EntityManager entityManager; > > @Resource(name = "jdbc/abcDSNoTX") > DataSource datasource; > > @Resource > private UserTransaction userTransaction; > > public void onMessage(Message message) { > try { > Processor processor = new Processor(entityManager, userTransaction, datasource); > processor.process(message); > .... Then further down the stack we begin a new userTransaction and load some entity via the entity manager > ... > m_userTransaction.begin(); > Account account = m_entityManager.find(Account.class, accountId); > ... > > account.getRelatedAccounts(); However further down the stack we access a collection on the account which loads further linked entities and failes with the LazyInitializationException. This problem only occurs under load and is most likely caused by a slow down while accessing the database. However I am not too concerned about performance at this stage, just want to know how I can debug this issue and see what happened to my entity manager session. My suspicion is that since I am using a User Transaction that the global timeout which I set to 3600 (=1 hour) is not applied. If this is the case where do you set the default transaction timeout for a user transaction or the hibernate session. Usually the first time the exception is thrown is between 20 and 30 minutes after submitting a large volume of work. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528562#528562

[JNDI and Naming] New message: "Re: jndi.properties vs bindings-jboss-beans.xml"

by Brian Stansberry

User development, A new message was posted in the thread "jndi.properties vs bindings-jboss-beans.xml": http://community.jboss.org/message/528556#528556 Author : Brian Stansberry Profile : http://community.jboss.org/people/bstansberry@jboss.com Message: -------------------------------------------------------------- You shouldn't need to provide any URL at all for a client running inside the AS to find the Naming server running inside the AS. The Context implementation class has a static reference to the in-VM naming server and uses that if no java.naming.provider.url is provided. That's why specifying a java.naming.provider.url breaks things or at best slows them down if what you're trying to do is access the local server. -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528556#528556

[JBoss Microcontainer Development] New message: "Re: VFS3 and symlinks"

by Ales Justin

User development, A new message was posted in the thread "VFS3 and symlinks": http://community.jboss.org/message/528555#528555 Author : Ales Justin Profile : http://community.jboss.org/people/alesj Message: -------------------------------------------------------------- > Just want to say that if this is the correct fix, it should not be optional. > I don't see any other way of fixing this -- force all paths to be canonical. But I would expect that this call is not cheap, asking the underlying FS for canonical path. And since 99% of users are not using symlinks (at least that's what I would expect), making this force optional makes sense. > No point in allowing configurations which aren't valid. I don't get this. Unfortunately I think the problem is even bigger than just VFS::getChild. My guess is that even calls to VirtualFile::getChild are due to fail with symlinked path? -------------------------------------------------------------- To reply to this message visit the message page: http://community.jboss.org/message/528555#528555

[JBoss Messaging] New message: "Redelivery Delay and Redelivery Times"

by null null

User development, A new message was posted in the thread "Redelivery Delay and Redelivery Times": http://community.jboss.org/message/528543#528543 Author : null null Profile : http://community.jboss.org/people/Paul_ADP Message: -------------------------------------------------------------- >From all of the documentation for JBM 1.4 (integrated into JBoss 5.1.0) it appears that for both: - MaxDeliveryAttempts - the number of times a message will be delivered to an MDB before being pushed to the DLQ - DeliveryDelay - the delay between subsequent redeliveries of the message to an MDB these values can ONLY be configured on a per destination basis (ie per Queue or Topic) and not per message. Is this true? I could swear the when I used JBoss MQ that you could set it in the message. Can someone please confirm?
