[jBPM] - BPM5Processor - JBossESB

by Vu Kien Pham

Vu Kien Pham [https://community.jboss.org/people/vukien] created the discussion "BPM5Processor - JBossESB" To view the discussion, visit: https://community.jboss.org/message/751974#751974 -------------------------------------------------------------- Dear Community, I've successfully deployed a process on JBPM console. This process consists of different Task forms, Java and JBossESB work items (imported from public Service Repository) It would be ok if I only have to trigger it in console. But now I've got problem regarding triggering this process externally. My question is if it is possible to trigger this process by using BPM5Processor from JBossESB and how? The idea is that a message is sent to ESB to trigger this JBPM process As I read in the Service Guide, ESB can start a process that has been deployed to jBPM but all I can do is to start a simple process with script tasks within Eclipse. I got no idea how to make the BPM5Processor aware of a already deployed process. Would appreciate if anyone can give me some suggestions. I'm using: JBPM 5.2 JBoss 5.1.0 GA JBoss ESB 4.11 Java 7 Thanks! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/751974#751974] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Re: When to call kSession.dispose()?

by Sukumaran Raghavan

Sukumaran Raghavan [https://community.jboss.org/people/suku_1983] created the discussion "Re: When to call kSession.dispose()?" To view the discussion, visit: https://community.jboss.org/message/732800#732800 -------------------------------------------------------------- +1 .... I use multiple sessions in my application and i dispose these as soon as i create a new process instance (basically each process instance has its own session). Once i register the work item, i dispose the ksession. I have also passed the ksession as a parameter to my work item handlers and they in turn save the ksession. Basically i want to call ksession.getWorkItemManager().completeWorkItem(workItemId). Now i am not sure if that call will work or not. It seems to work which is surprising. especially since i disposed my ksession ? How does this all work ? A lil clarity would help me make more apt design decisions. Thanks in advance.! ! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/732800#732800] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Intermittently pending human task come across a missing jbpm parent process in jBPM 5.2

by Dev S

Dev S [https://community.jboss.org/people/devinderpal] created the discussion "Intermittently pending human task come across a missing jbpm parent process in jBPM 5.2" To view the discussion, visit: https://community.jboss.org/message/752342#752342 -------------------------------------------------------------- Env: Jboss 7.1.0, mysql DB, Redhat 5.5, jBPM 5.2 When I thought I'm getting pretty good with jBPM and our application is about to be released, i came across this tough bug during extensive testing. Intermittently we're facing that pending human task has missing parent process instance and it results in nullpointerexception while completing that human task. I ran below SQL query to confirm this: select t.id, t.processInstanceId from Task t where t.processInstanceId not in (select distinct(InstanceId) from ProcessInstanceInfo); +----+-------------------+ | id | processInstanceId | +----+-------------------+ | 33 | 20 | | 43 | 20 | | 47 | 20 | | 53 | 20 | | 57 | 20 | +----+-------------------+ Same code works fine most of the time. So I think it's not problem with our code but some bug in jBPM. MinaTaskServer is being used for our implementation. Also we use JTA persistence for jBPM core engine and RESOURCE_LOCAL for human task. We have to use RESOURCE_LOCAL for human task because JTA can't be used due to another jBPM bug. If I reinitialize the database, then everything works fine for a while but again I run into this problem. Please let us know how we can fix it, if anyone knows solution. I was about to create a blocker JIRA issue but thought let's first get community opinion on this. Exception stack trace is attached. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/752342#752342] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - SignalEvent issue in jBPMConsole

by Herman Post

Herman Post [https://community.jboss.org/people/hbpost] created the discussion "SignalEvent issue in jBPMConsole" To view the discussion, visit: https://community.jboss.org/message/757107#757107 -------------------------------------------------------------- We have run into an issue with jbpmConsole that we do not understand. The sample code runs as expected in eclipse but does not run the same in jbpmConsole. (project attached running jBPM 5.3/Drools 5.4) The sample demonstrates starting two different processes in the same kSession and having one process signal an event in the other process. The sample code in ProcessApp creates an instance of Hello.bpmn which blocks waiting for a SignalEvent. It then creates an instance of DataDriveProcess.bpmn which has a single action node that calls kcontext.getKnowledgeRuntime().signalEvent("TestSignal", false); In eclipse this works fine and the Hello process terminates when it receives the SignalEvent from DataDriveProcess. If these processes are uploaded to Guvnor and packaged, and then started in jbpmConsole, Hello process does not receive the SignalEvent. It can be made to work though, if you start the Hello process, note the processInstanceId, then edit the DataDriveProcess in Guvnor to call signalEvent("TestSignal", false, 8) with the explicit processInstanceId, and rebuild and start DataDriveProcess. So to summarize, signalEvent in 'broadcast' mode, without a specific processInstanceId does not appear to work in jbpmConsole, but does work in eclipse. We also tried to iterate through all of the process instances from the Action node in jbpmConsole and just SignalEvent on each, but no other process instances are visible. They are visible in eclipse.
