[JBoss JIRA] Commented: (JBPM-1072) Concurrent JobExecutors can process the same job in parallel

by Alexey Kostylev (JIRA)

[ http://jira.jboss.com/jira/browse/JBPM-1072?page=comments#action_12392637 ] Alexey Kostylev commented on JBPM-1072: --------------------------------------- Is it possible to use several JobExecutors with non-transactional ActionHandlers? As I understand the problem is that the same job is loaded by several JobExecutors and one job is executed several time. When job makes some non-transactional action, as writing is file, this is not acceptable. May be pessimistic locking should help? > Concurrent JobExecutors can process the same job in parallel > ------------------------------------------------------------ > > Key: JBPM-1072 > URL: http://jira.jboss.com/jira/browse/JBPM-1072 > Project: JBoss jBPM > Issue Type: Bug > Components: Core Engine > Affects Versions: jBPM jPDL 3.2.2 > Environment: Linux 2.6.21-1.3228.fc7 #1 SMP Tue Jun 12 14:56:37 EDT 2007 x86_64 x86_64 x86_64 GNU/Linux > MySQL 5.0.22 > Reporter: Jiri Pechanec > Assigned To: Koen Aers > Attachments: expl.tar.gz > > > Attached is a simple test case that > 1) Deploys process definition with two nodes > 2) Starts 20 executor threads > 2) Starts the process instance that will asynchronously execute action on the second node > 4) The second node writes a record to the database > The test case needs to be executed multiple times to see the incorrect behaviour. > This is an example of run output > Isol 8 > Action 1 > Success 0 > Failure 0 > Action 2 > Action 2 1 > Action 2 > Action 2 1 > Action 2 > Action 2 1 > Action 2 > Action 2 1 > Action 2 > Action 2 1 > Action 2 > Action 2 1 > Action 2 > Action 2 > Action 2 1 > Action 2 1 > Action 2 > Action 2 1 > Explanation of the outcome > 9 job executors successfully executed the node action (same job) including database operation.

[JBoss JIRA] Commented: (JBPM-895) null pointer when create new sub process definition

by Michael Thiele (JIRA)

[ http://jira.jboss.com/jira/browse/JBPM-895?page=comments#action_12392258 ] Michael Thiele commented on JBPM-895: ------------------------------------- I had a hard time solving this problem. It's not a bug, it's just not well designed... You don't have to do some kind of bug fix like replacing above said code. You have to make sure, that the sub-process is already deployed, when the main process is being parsed from your processdefinition.xml file. So things like this won't work: ProcessDefinition pdload_sub = ProcessDefinition.parseXmlResource("sub.xml"); ProcessDefinition pdload_caller = ProcessDefinition.parseXmlResource("main.xml"); context.deployProcessDefinition(pdload_sub); context.deployProcessDefinition(pdload_caller); Instead you have to do it that way: ProcessDefinition pdload_sub = ProcessDefinition.parseXmlResource("sub.xml"); context.deployProcessDefinition(pdload_sub); ProcessDefinition pdload_caller = ProcessDefinition.parseXmlResource("main.xml"); context.deployProcessDefinition(pdload_caller); That's sometimes not that easy, since these method calls can be distributed different classes etc., but keep in mind, that resolving the sub-process definition from the given name takes place during parsing, not during deployment of the main process! Besides what Tom B. posted is right for the issue description: parsing of the definition xml has to take place after a JbpmContext has been created. After deployment of the ProcessDefinition it will be persisted with the jbpmContext.close(); in the finally block. If you parse outside the try block (that is without having created a JbpmContext) JBPM won't find the persisted sub-process referenced in the main process definition. > null pointer when create new sub process definition > --------------------------------------------------- > > Key: JBPM-895 > URL: http://jira.jboss.com/jira/browse/JBPM-895 > Project: JBoss jBPM > Issue Type: Bug > Components: BPEL > Affects Versions: jBPM 3.1.3 > Reporter: Tom Nguyen > Assigned To: Tom Baeyens > Attachments: DbSubProcessResolver.java > > > I have a problem with my process composition > Exception happen when deploying process with sub process: > public void deployProcessDefinition() { > ProcessDefinition processDefinition = ProcessDefinition.parseXmlResource("main/processdefinition.xml"); > ProcessInstance instance = new ProcessInstance(processDefinition); > JbpmContext jbpmContext = jbpmConfiguration.createJbpmContext(); > try { > jbpmContext.deployProcessDefinition(processDefinition); > } finally { > jbpmContext.close(); > } > } > java.lang.NullPointerException: can't create a process instance when processDefinition is null > at org.jbpm.graph.exe.ProcessInstance.<init>(ProcessInstance.java:87) > at org.jbpm.graph.exe.Token.createSubProcessInstance(Token.java:571) > at org.jbpm.graph.node.ProcessState.execute(ProcessState.java:109) > at org.jbpm.graph.def.Node.enter(Node.java:316) > <?xml version="1.0" encoding="UTF-8"?> > <process-definition > xmlns="urn:jbpm.org:jpdl-3.1" name="main"> > <start-state name="start"> > </start-state> > <end-state name="end"></end-state> > <process-state name="sub"> > <sub-process name="sub"/> > </process-state> > </process-definition> > This is my sub process: > <?xml version="1.0" encoding="UTF-8"?> > <process-definition > xmlns="urn:jbpm.org:jpdl-3.1" name="sub"> > <start-state name="start"> > </start-state> > <end-state name="end"></end-state> > </process-definition> -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://jira.jboss.com/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
