Doubt regarding the Timer Task?

[guideme]

Hi

Timer task executes based on business calendar properties file. Could you please tell me overridding the existing business calendar properties file is possible in jBPM and if so where I need to place the overridden business calendar properties file. Can I place business calendar properties file in the src/config.files location?

<start-state name="start">
<transition name="test_transition" to="init">
<action name="SimpleTransitionTest" class="com.sample.TestTransition"></action>
</transition>
</start-state>

<state name="init">
<transition name="to_end" to="end"></transition>
<timer duedate="1 business hours" name="TimerTest" repeat="2 minutes">
<action name="MyTimerTask" class="com.sample.TestBean"/>
</timer>

</state>

<end-state name="end">
<event type="node-enter">
<cancel-timer name="TimerTest"/>
</event>
</end-state>

I implemented the Timer task. When I execute my code, the action class (com.sample.TestBean) associated with the timer never get executed? Could you please tell me what I am doing wrong?

ProcessDefinition definition = ProcessDefinition.parseXmlResource("testtimer.par/processdefinition.xml");

ProcessInstance instance = new ProcessInstance(definition);

System.out.println("instance in start state = " + instance.getRootToken().getNode().getName()); // It prints "start"

instance.signal();

System.out.println("instance in initialize state = " + instance.getRootToken().getNode().getName()); // It prints "init"

instance.signal();

System.out.println("instance in end state = " + instance.getRootToken().getNode().getName()); // It prints "end"

The docs are your friend : http://docs.jboss.com/jbpm/v3/userguide/businesscalendar.html.
Just place the file somewhere on the classpath...

In fact then you define timer in your processdefinition it is not executed.
It will be created in special table jbom_timer suring executing of process_instance. . And you should have a schedulerthread running: it will execute timers that are created. To start scheduler thread you can call special servlet which is included into jbpm.war

Koen, the sources are an even better friend. You said:

Just place the file somewhere on the classpath...

But the docs say:

The configuration file can be customized and a modified copy can be placed in the root of the classpath.

The sources say (best docs there are ;-)) say you are right, so maybe it should be 'koen is your friend' :-P
