Hi, I've got a drools application running with EJB3 and JBoss 5.1. It works fine but most of the times it throws exception while trying to load drools session from JPA. My flow has got user tasks so it stops at places and get stored in db using JPA. Then I try to load it by providing the session id which does exist in database but it fails to load with following exception: Caused by: Could not commit session 2010-12-21 00:47:16,453 ERROR [STDERR] (pool-37-thread-1) java.lang.IllegalStateException: Wrong tx on thread: expected TransactionImple < ac, BasicAction: a64360d:8184:4d0ff52a:18d status: ActionStatus.ABOR TED >, actual null 2010-12-21 00:47:16,453 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aspects.tx.TxPolicy.endTransaction(TxPolicy.java:157) 2010-12-21 00:47:16,453 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aspects.tx.TxPolicy.invokeInOurTx(TxPolicy.java:87) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aspects.tx.TxInterceptor$Required.invoke(TxInterceptor.java:190) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aspects.tx.TxPropagationInterceptor.invoke(TxPropagationInterceptor.java:76) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.ejb3.tx.NullInterceptor.invoke(NullInterceptor.java:42) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.ejb3.security.Ejb3AuthenticationInterceptorv2.invoke(Ejb3AuthenticationInterceptorv2.java:186) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.ejb3.ENCPropagationInterceptor.invoke(ENCPropagationInterceptor.java:41) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.ejb3.BlockContainerShutdownInterceptor.invoke(BlockContainerShutdownInterceptor.java:67) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aspects.currentinvocation.CurrentInvocationInterceptor.invoke(CurrentInvocationInterceptor.java:67) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.ejb3.stateless.StatelessContainer.dynamicInvoke(StatelessContainer.java:421) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.ejb3.remoting.IsLocalInterceptor.invokeLocal(IsLocalInterceptor.java:85) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.ejb3.remoting.IsLocalInterceptor.invoke(IsLocalInterceptor.java:72) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aop.joinpoint.MethodInvocation.invokeNext(MethodInvocation.java:102) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at org.jboss.aspects.remoting.PojiProxy.invoke(PojiProxy.java:62) 2010-12-21 00:47:16,454 ERROR [STDERR] (pool-37-thread-1) at $Proxy678.invoke(Unknown Source) Does anyone know how to get around this issue?
