Mike Panetta [http://community.jboss.org/people/blarevil] created the discussion "Error in Sample Task Service" To view the discussion, visit: http://community.jboss.org/message/613053#613053 -------------------------------------------------------------- I just downloaded the jbpm 5.1 full installer.  After installing and starting the demo, I went into the jbpm console and created a new instance of the evaulation process.  Upon doing this, I get an error in the human task service (see below).  Any idea what I may be missing here?  Looks like some data is missing in the OrganizationalEntity table and I'm not sure how to go about loading this. Does this have anything to with the LoadUsers.mvel and LoadGroups.mvel files that are loaded when the task starts? I tried connecting to the H2 Database through eclipse, but I do not see any tables in this system. I treid out the jbpm 5.0 installer and have the same problem.  Several months ago I was able to get this demo running under the Drools Flow project, but I cannot find a download page for this project anymore. javax.persistence.RollbackException: Error while commiting the transaction     at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:71)     at org.jbpm.task.service.TaskServiceSession.doOperationInTransaction(TaskServiceSession.java:820)     at org.jbpm.task.service.TaskServiceSession.addTask(TaskServiceSession.java:134)     at org.jbpm.task.service.TaskServerHandler.messageReceived(TaskServerHandler.java:109)     at org.jbpm.task.service.mina.MinaTaskServerHandler.messageReceived(MinaTaskServerHandler.java:41)     at org.apache.mina.core.filterchain.DefaultIoFilterChain$TailFilter.messageReceived(DefaultIoFilterChain.java:713)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.callNextMessageReceived(DefaultIoFilterChain.java:434)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.access$1200(DefaultIoFilterChain.java:46)     at org.apache.mina.core.filterchain.DefaultIoFilterChain$EntryImpl$1.messageReceived(DefaultIoFilterChain.java:793)     at org.apache.mina.filter.codec.ProtocolCodecFilter$ProtocolDecoderOutputImpl.flush(ProtocolCodecFilter.java:375)     at org.apache.mina.filter.codec.ProtocolCodecFilter.messageReceived(ProtocolCodecFilter.java:229)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.callNextMessageReceived(DefaultIoFilterChain.java:434)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.access$1200(DefaultIoFilterChain.java:46)     at org.apache.mina.core.filterchain.DefaultIoFilterChain$EntryImpl$1.messageReceived(DefaultIoFilterChain.java:793)     at org.apache.mina.filter.logging.LoggingFilter.messageReceived(LoggingFilter.java:176)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.callNextMessageReceived(DefaultIoFilterChain.java:434)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.access$1200(DefaultIoFilterChain.java:46)     at org.apache.mina.core.filterchain.DefaultIoFilterChain$EntryImpl$1.messageReceived(DefaultIoFilterChain.java:793)     at org.apache.mina.core.filterchain.IoFilterAdapter.messageReceived(IoFilterAdapter.java:119)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.callNextMessageReceived(DefaultIoFilterChain.java:434)     at org.apache.mina.core.filterchain.DefaultIoFilterChain.fireMessageReceived(DefaultIoFilterChain.java:426)     at org.apache.mina.core.polling.AbstractPollingIoProcessor.read(AbstractPollingIoProcessor.java:638)     at org.apache.mina.core.polling.AbstractPollingIoProcessor.process(AbstractPollingIoProcessor.java:598)     at org.apache.mina.core.polling.AbstractPollingIoProcessor.process(AbstractPollingIoProcessor.java:587)     at org.apache.mina.core.polling.AbstractPollingIoProcessor.access$400(AbstractPollingIoProcessor.java:61)     at org.apache.mina.core.polling.AbstractPollingIoProcessor$Processor.run(AbstractPollingIoProcessor.java:969)     at org.apache.mina.util.NamePreservingRunnable.run(NamePreservingRunnable.java:64)     at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886)     at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908)     at java.lang.Thread.run(Thread.java:680) Caused by: org.hibernate.exception.ConstraintViolationException: Could not execute JDBC batch update     at org.hibernate.exception.SQLStateConverter.convert(SQLStateConverter.java:94)     at org.hibernate.exception.JDBCExceptionHelper.convert(JDBCExceptionHelper.java:66)     at org.hibernate.jdbc.AbstractBatcher.executeBatch(AbstractBatcher.java:275)     at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:266)     at org.hibernate.engine.ActionQueue.executeActions(ActionQueue.java:168)     at org.hibernate.event.def.AbstractFlushingEventListener.performExecutions(AbstractFlushingEventListener.java:321)     at org.hibernate.event.def.DefaultFlushEventListener.onFlush(DefaultFlushEventListener.java:50)     at org.hibernate.impl.SessionImpl.flush(SessionImpl.java:1027)     at org.hibernate.impl.SessionImpl.managedFlush(SessionImpl.java:365)     at org.hibernate.transaction.JDBCTransaction.commit(JDBCTransaction.java:137)     at org.hibernate.ejb.TransactionImpl.commit(TransactionImpl.java:54)     ... 29 more Caused by: org.h2.jdbc.JdbcBatchUpdateException: Referential integrity constraint violation: "FK27A9A59E619A0: PUBLIC.TASK FOREIGN KEY(CREATEDBY_ID) REFERENCES PUBLIC.ORGANIZATIONALENTITY(ID)";
