[jboss-jira] [JBoss JIRA] Commented: (JBPM-681) GraphElement.raiseException results in Exception with Java EE

GraphElement.raiseException results in Exception with Java EE ------------------------------------------------------------- Key: JBPM-681 URL: http://jira.jboss.com/jira/browse/JBPM-681 Project: JBoss jBPM Issue Type: Bug Components: Core Engine Affects Versions: jBPM 3.1.1 Environment: Java EE with JTA Reporter: Bernd Ruecker Assigned To: Tom Baeyens Priority: Critical If you - invoke a SessionBean in a jbpm action - jBPM and the SessionBean run in the same JTA transaction - a Exception occurs Then the Transaction is marked for rollback from the EJB-Container when the Exception occurs in the SessionBean. Now jBPM wants to handle the Exception (see http://docs.jboss.com/jbpm/v3/userguide/processmodelling.html#exceptionha...): When an exception occurs in a delegation class, the process element parent hierarchy is serached for an appropriate exception-handler. When it is found, the actions of the exception-handler are executed But becaue the transaction is already marked for rollback, a call to Hibernate (lazy loading?) results in a exception: 7:14:29,875 INFO [DefaultLoadEventListener] Error performing load command org.hibernate.exception.GenericJDBCException: Cannot open connection at org.hibernate.exception.SQLStateConverter.handledNonSpecificException(SQLStateConverter.java:103 ) at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:91) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:43) at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:29) at org.hibernate.jdbc.ConnectionManager.openConnection(ConnectionManager.java:420) at org.hibernate.jdbc.ConnectionManager.getConnection(ConnectionManager.java:144) at org.hibernate.jdbc.AbstractBatcher.prepareQueryStatement(AbstractBatcher.java:139) at org.hibernate.loader.Loader.prepareQueryStatement(Loader.java:1561) at org.hibernate.loader.Loader.doQuery(Loader.java:661) at org.hibernate.loader.Loader.doQueryAndInitializeNonLazyCollections(Loader.java:224) at org.hibernate.loader.Loader.loadEntity(Loader.java:1785) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:48) at org.hibernate.loader.entity.AbstractEntityLoader.load(AbstractEntityLoader.java:42) at org.hibernate.persister.entity.AbstractEntityPersister.load(AbstractEntityPersister.java:2821) at org.hibernate.event.def.DefaultLoadEventListener.loadFromDatasource(DefaultLoadEventListener.jav a:370) at org.hibernate.event.def.DefaultLoadEventListener.doLoad(DefaultLoadEventListener.java:351) at org.hibernate.event.def.DefaultLoadEventListener.load(DefaultLoadEventListener.java:122) at org.hibernate.event.def.DefaultLoadEventListener.onLoad(DefaultLoadEventListener.java:81) at org.hibernate.impl.SessionImpl.fireLoad(SessionImpl.java:871) at org.hibernate.impl.SessionImpl.immediateLoad(SessionImpl.java:829) at org.hibernate.proxy.AbstractLazyInitializer.initialize(AbstractLazyInitializer.java:66) at org.hibernate.proxy.AbstractLazyInitializer.getImplementation(AbstractLazyInitializer.java:111) at org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:160) at org.jbpm.graph.def.Node$$EnhancerByCGLIB$$cb896060.equals(<generated>) at org.jbpm.util.EqualsUtil.equals(EqualsUtil.java:30) at org.jbpm.graph.def.GraphElement.equals(GraphElement.java:418) at org.jbpm.graph.def.GraphElement$$FastClassByCGLIB$$7a7d6aa6.invoke(<generated>) at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) at org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:163) at org.jbpm.graph.node.TaskNode$$EnhancerByCGLIB$$78d101e.equals(<generated>) at org.jbpm.graph.def.Transition.getParent(Transition.java:204) at org.jbpm.graph.def.GraphElement.raiseException(GraphElement.java:338) at org.jbpm.graph.def.GraphElement.executeAction(GraphElement.java:248) at org.jbpm.graph.def.GraphElement.executeActions(GraphElement.java:212) at org.jbpm.graph.def.GraphElement.fireAndPropagateEvent(GraphElement.java:182) at org.jbpm.graph.def.GraphElement.fireEvent(GraphElement.java:166) at org.jbpm.graph.def.Transition.take(Transition.java:106) at org.jbpm.graph.def.Node.leave(Node.java:382) at org.jbpm.graph.node.TaskNode.leave(TaskNode.java:198) at org.jbpm.graph.def.Node$$FastClassByCGLIB$$d187eeda.invoke(<generated>) at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) at org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:163) at org.jbpm.graph.def.Node$$EnhancerByCGLIB$$cb896060.leave(<generated>) at org.jbpm.graph.exe.Token.signal(Token.java:174) at org.jbpm.graph.exe.Token.signal(Token.java:145) at org.jbpm.graph.exe.Token$$FastClassByCGLIB$$74df1c6e.invoke(<generated>) at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) at org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:163) at org.jbpm.graph.exe.Token$$EnhancerByCGLIB$$fae2cddc.signal(<generated>) at org.jbpm.taskmgmt.exe.TaskInstance.end(TaskInstance.java:420) at org.jbpm.taskmgmt.exe.TaskInstance.end(TaskInstance.java:359) at org.jbpm.taskmgmt.exe.TaskInstance$$FastClassByCGLIB$$cb2c21af.invoke(<generated>) at net.sf.cglib.proxy.MethodProxy.invoke(MethodProxy.java:149) at org.hibernate.proxy.pojo.cglib.CGLIBLazyInitializer.intercept(CGLIBLazyInitializer.java:163) at org.jbpm.taskmgmt.exe.TaskInstance$$EnhancerByCGLIB$$cbd8230f.end(<generated>) at com.camunda.toolkit.jbpm.service.AdminServicesImpl.endTask(AdminServicesImpl.java:1452)
