Problems using timers from jbpm

miggfried Jun 8, 2009 11:27 AM

Hi, can someone help me regarding my problems using timers.

I get an exception, which i do not understand.

- JBOSS-4.2.1.GA

- JBPM3.2.6.SP1

adding in jbpm.cfg.xml the following line

<jbpm-context>
.......

.......
</jbpm-context>

This is my process

<process-definition xmlns="urn:jbpm.org:jpdl-3.2" name="mainProcess">
<start-state name="start">

</start-state>

here comes the timer, the preview always deletes my lines ...

<end-state name="end"></end-state>
</process-definition>

I do the following steps

- deploy the process with GPD

- start an instance of the process

- signal on token 'start'

i get these exception:

maybe i try to establish a new transaction and an old transaction is not closed.
I do not really understand

Sorry,I can't understand your question either.But i can give you some code about using Timer which i had successfully tested.i hope it's useful for you.

<task-node name="timer" end-tasks="true">

</task-node>

public class TimerAction implements ActionHandler {

public void execute(ExecutionContext executionContext) throws Exception {
executionContext.leaveNode("dispute");
}
}

Hi, think you for your response.

My Problem is not thy synatk of the element timer.

My problem is how to configure my jboss/jbpm to save timers.

I always get the exception if i try to save these timer (over
javax.ejb.Timer from J2EE).

I only do the following steps:

I install my jboss

i install jbpm as service in jboss

i add one line in jbpm.cfg.xml

with the correct factory

org.jbpm.scheduler.ejbtimer.EntitySchedulerServiceFactory

I always get the exception from my post entry before.

There must be something more to configure to leverage the J2EE Environment for timers

Also I can not use the websale example.

If execution arrives in an node, which has a timer i get the exception.

Do you understand my problem ..

My english is not so good

sorry
