I don't know if i have to set something in order to connect to the server, because i
have set the IpAddress and the port but still from the localhost:8080/jbpm-console i
can't see my processes i only see the evaluation.bpmn that i got from the
jbpm-installer folder

So, what are you trying to achieve?
In order to register a WorkItemHandler against a Task Server you need to know where your
task service is.
Did you start an instance of a task server?
Cheers

You will need to share more information with us you want our help.
localhost? are you using the jBPM Console? are you using eclipse? are you creating your
own application embeding jBPM5 in it? Can you describe the components that you are using?
Cheers

Hello, Mauricio!
I've got the same problem. And I can share some info about problem:
- I'm using jbpm-5.3.0.Final-installer with example "Evaluation" on
localhost
- I've added additional business process, called "test.bpmn2", added
additional java-class "ProcessTest_debtOff", like "ProcessTest" from
example
- I've got exception like https://community.jboss.org/people/mab1990.amu RSTVMA
LDHYAGF, when I tried to start my test process from java class.
Java code and BPMN-style process are in attached files.
Thank You for your help

I'm running the latest JBPM Demo setup (jbpm 5.3.0 Final), following the first
tutorial (Evaluation sample) in the user guide (Using the Eclipse tooling) and I get the
same error as the original poster. It works on the first run after just starting the demo,
but after stopping the process and run it again it throws the following error:
ERROR workitem.wsht.GenericHTWorkItemHandler.executeWorkItem - Thu Jul 26 11:21:00 CEST
2012: Error when creating task on task server for work item id 1. Error reported by task
server: Task operation request timed out
java.lang.RuntimeException: Task operation request timed out
Any idea why?

Make sure that you have your task server up and running

I have started the demo enviroment with ant start.demo, and I can view and complete tasks
through the jBPM Console without issues so I would suppose the task server is up and
running.

Hello Mauricio,
I'm using the jBPM Console and eclipse. But I don't know if its possible because
the project that we are doing we using Flash Builder as the front-end, so is there any way
to intergrate Flash builder and JBPM.
The localhost that i use is: http://localhost:8080/jbpm-console
http://localhost:8080/jbpm-console and for my tasks i use the ip address 127.0.0.1 and
port 5445.

Hi,
I'm having similar issue.
I have installed jBPM 5.3 final with ant install.demo.
I have started all processes with ant start.demo
I have made a small workflow with a start event, a human task event and an end event
I have made a program to start the workflow and then in a loop monitor the status of the
workflow.
I get inconsistent behaviour.
Sometimes it all works as expected:
-Human task gets created and becomes visible in human task view in eclipse
-Program reports that process is active.
-The program goes into a loop whereby it validates the workflow status each 3 seconds, as
long as the workflow is still active and reports on the status.
-I use the human task view in eclipse to start and complete the task
-As soon as the task is completed, the program reports that the process is no longer
active
Sometimes it acts weird in one way:
-The program reports the above mentioned time-out while starting the workflow
-However, the human task does become visibible in human task view in eclipse, so the
creation is successfull, despite the exception
-The program reports that the process is active and keeps reporting it, until I complete
the human task with the human task view in eclipse, after which the program reports that
the workflow is completed.
Sometimes it acts weird in another way:
-The human task gets created and becomes visible in human task view in eclipse. I
don't get any exceptions.
-On first iteration, program reports that the process is active (as expected)
-On second iteration, program reports that the process is completed.
-The human task however is still in status 'reserved', as I did not yet start and
complete the human task using the human task viewer.
Any help in troubleshooting these issues is appreciated
Thanks and kind regards,
Alex

Hi guys,
I am having exactly the same issue with the demo. In Eclipse, the first time I run
"Debug as .." Java application, everything goes smoothly. I start all the tasks,
terminate them, let the debugger go till the end, and later terminate.
If I run inmediately after "Debug as .." then I got the nasty error "Error
when creating task on task server for work item id 1. Error reported by task server: Task
operation request ..."
It only disappears when I stop the demo, clean the db (ant clean.db) and restart again..
quite annoying...

Sorry to go off thread but to reply to *toorop*, it sounds like you've hit the same
issue as me ( https://community.jboss.org/thread/223191 Cannot make Evaluation example
work consistently in Eclipse).
I've not had time to revisit it since, but I think it may be something to do with the
example code (ProcessTest) not disposing of the human task at the end of the demo.
Not very helpful I know, but at least you know you are not alone :)
