1. Re: Async Fork Transaction Issues
swiderski.maciej Apr 1, 2010 1:44 PM (in response to rhodos)HI,
when I run your process (but with my simple test classes - you did not attach source) including your configuration test fails indeed.
What I did to make it to work was to disable jobexecutor in jbpm.cfg.xml. After that change test went well. I tested that for both 4.3 and 4.4.
If that would not help you please post source for custom nodes I will try to dig a bit deeper.

rhodos Apr 1, 2010 2:18 PM (in response to swiderski.maciej)Hi,
Sorry about that, here is the sourcecode.
The problem is that I need it to work with the job executor, because I need concurrent forked executions.
Thanks for looking into it.

3. Re: Async Fork Transaction Issues
swiderski.maciej Apr 9, 2010 1:56 PM (in response to rhodos)Hi Rachel,
took me some time to look deeper into your issue but finally I did it. Here are some explanations:
2) When run as a unit test, each node only prints its name once, and the test passes.
This is due to not enough time for job executors to finish their job, I mean that your main thread (junit) will kill all child threads as soon it will go through the loop. Just put a sleep on your main class and you should get all print outs from your custom nodes.
1) When run as a Java application , the following exception is thrown:
org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.pvm.internal.model.ExecutionImpl#7]
I could reproduce that only when I manually executed job at the same time job executors were running. Moreover, I did deploy it to db and then run it from console and it worked fine. Did you try to run it from console?!

rhodos Apr 12, 2010 4:17 AM (in response to swiderski.maciej)Hi Maciej,
Thanks so much for working on this!
I've been trying to run it from the console but I am having some issue with my configuration (see my other post: http://community.jboss.org/message/535308#535308).
Also, what is the point of a unit test? Can this run operationally from the console somehow or is it only meant for testing purposes?

swiderski.maciej Apr 12, 2010 4:59 AM (in response to rhodos)Hi Rachel,
I would say that unit tests are only to verify that everything works as expected in isolation - so yes, only testing purposes.
Could you provide some information about how did you install jBPM and details about your environment - what server, what db, etc.
Cheers,
Maciej

6. Re: Async Fork Transaction Issues
rhodos Apr 12, 2010 3:28 PM (in response to swiderski.maciej)Maciej,
I am using jBPM 4.3 with jBoss, HSQLDB, Java 1.6, on a Linux OS. I don't know what information I can give about how I installed jBPM; I just add the jar files to my classpath.. I am sending a new copy of my source code, as it's slightly changed, and I'm also attaching the the parser I'm using. The error seems to be with parsing jbpm.cfg.xml. No matter how I change this file (I've tried unchanged, removing the first line, commenting everything out, etc.), I get this error:

7. Re: Async Fork Transaction Issues
rebody Apr 13, 2010 1:37 AM (in response to rhodos)Hi Rachel,
The error is most likely there is invalid character in the jbpm.cfg.xml. I am afraid your jbpm.cfg.xml may be broken by some reason. You should find a new jbpm.cfg.xml from jBPM distribution, overwrite the old one, and try again.

8. Re: Async Fork Transaction Issues
swiderski.maciej Apr 13, 2010 1:01 PM (in response to rhodos)Hi,
I am not sure it should be xerces - at least it is not part of jBPM distribution.
I would suggest to create your class path strictly based on following libraries:
- ${jbpm43.home}/jbpm.jar
- ${jbpm43.home}/*.jar
Of course you could add your own classes as well but please be careful with adding any xml parsers.
Cheers,
Maciej

9. Re: Async Fork Transaction Issues
rhodos Apr 13, 2010 3:34 PM (in response to swiderski.maciej)Maciej,
You're right- I don't get that error when I simplify my classpath to include only jbpm jars. This is good! :]
Now, when you said that you got it working from the console, did it work with the threads running concurrently (i.e. printing something like "A, B, A, A, B.."?

13. Re: Async Fork Transaction Issues
rhodos Apr 14, 2010 5:11 PM (in response to swiderski.maciej)Maciej,
With the source code I sent you, I get a NullPointerException because repositoryService isn't defined.
When I add the following lines to the end of ConcurrencyTest.initialize() (and import the RepositoryService class):
repositoryService = processEngine.get(RepositoryService.class);
executionService = processEngine.getExecutionService();
the process gets farther but then throws the following exception:13:48:55,893 INF | [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.SignalCmd@15a4523org.jbpm.api.JbpmException: execution[TestConcurrencySimple.7.to A] is not active: asyncThen, if I comment out signalExecutionById, I get the original exception I was complaining about:
org.hibernate.StaleObjectStateException: Row was updated or deleted by another transaction (or unsaved-value mapping was incorrect): [org.jbpm.pvm.internal.model.ExecutionImpl#7]
How the heck did you get my source code to work??
(Sorry to keep throwing new questions at you.)
