Hello, i wrote a simple stateless bean to test the TimerService. i am using jboss 4.2.0GA
Whenerver i initialize the time i run into the following exception: 2007-10-02 14:56:55,437 ERROR [org.jboss.ejb.txtimer.TimerServiceImpl] Cannot create txtimer | java.lang.IllegalStateException: Unable to persist timer | at org.jboss.ejb.txtimer.DatabasePersistencePolicy.insertTimer(DatabasePersistencePolicy.java:124) | at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) | at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) | at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:25) | at java.lang.reflect.Method.invoke(Method.java:585) | at org.jboss.mx.interceptor.ReflectedDispatcher.invoke(ReflectedDispatcher.java:155) | ... | ... | at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:241) | at org.apache.coyote.ajp.AjpProcessor.process(AjpProcessor.java:437) | at org.apache.coyote.ajp.AjpProtocol$AjpConnectionHandler.process(AjpProtocol.java:381) | at org.apache.tomcat.util.net.JIoEndpoint$Worker.run(JIoEndpoint.java:447) | at java.lang.Thread.run(Thread.java:595) | Caused by: org.jboss.util.NestedSQLException: Could not enlist in transaction on entering meta-aware object!; - nested throwable: (javax.transaction.SystemException: java.lang.Throwable: Unabled to enlist resource, see the previous warnings. tx=TransactionImple < ac, BasicAction: -3f57fdff:555:47023fba:53 status: ActionStatus.ABORT_ONLY >); - nested throwable: (org.jboss.resource.JBossResourceException: Could not enlist in transaction on entering meta-aware object!; - nested throwable: (javax.transaction.SystemException: java.lang.Throwable: Unabled to enlist resource, see the previous warnings. tx=TransactionImple < ac, BasicAction: -3f57fdff:555:47023fba:53 status: ActionStatus.ABORT_ONLY >)) | at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:94) | at org.jboss.ejb.txtimer.GeneralPurposeDatabasePersistencePlugin.insertTimer(GeneralPurposeDatabasePersistencePlugin.java:199) | at org.jboss.ejb.txtimer.DatabasePersistencePolicy.insertTimer(DatabasePersistencePolicy.java:120) | ... 317 more | Caused by: org.jboss.resource.JBossResourceException: Could not enlist in transaction on entering meta-aware object!; - nested throwable: (javax.transaction.SystemException: java.lang.Throwable: Unabled to enlist resource, see the previous warnings. tx=TransactionImple < ac, BasicAction: -3f57fdff:555:47023fba:53 status: ActionStatus.ABORT_ONLY >) | at org.jboss.resource.connectionmanager.TxConnectionManager.managedConnectionReconnected(TxConnectionManager.java:343) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.reconnectManagedConnection(BaseConnectionManager2.java:518) | at org.jboss.resource.connectionmanager.BaseConnectionManager2.allocateConnection(BaseConnectionManager2.java:399) | at org.jboss.resource.connectionmanager.BaseConnectionManager2$ConnectionManagerProxy.allocateConnection(BaseConnectionManager2.java:842) | at org.jboss.resource.adapter.jdbc.WrapperDataSource.getConnection(WrapperDataSource.java:88) | ... 319 more | Caused by: javax.transaction.SystemException: java.lang.Throwable: Unabled to enlist resource, see the previous warnings. tx=TransactionImple < ac, BasicAction: -3f57fdff:555:47023fba:53 status: ActionStatus.ABORT_ONLY > | at org.jboss.resource.connectionmanager.TxConnectionManager$TxConnectionEventListener$TransactionSynchronization.checkEnlisted(TxConnectionManager.java:744) | at org.jboss.resource.connectionmanager.TxConnectionManager$TxConnectionEventListener.enlist(TxConnectionManager.java:577) | at org.jboss.resource.connectionmanager.TxConnectionManager.managedConnectionReconnected(TxConnectionManager.java:337) | ... 323 mor I googled a bit and found some issues. Now I still dont know what to do. Do i need to configure the TimerService with my database (MySQL)? I think for me its not neccessary to persist the status. Its enough for me if the timer is executed as long as the application is running. Any hints would be great. regards, hasc View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4090639#4090639 Reply to the post : http://www.jboss.com/index.html?module=bb&op=posting&mode=reply&p=4090639 _______________________________________________ jboss-user mailing list jboss-user@lists.jboss.org https://lists.jboss.org/mailman/listinfo/jboss-user
