I really fairly new to JCA development so maybe I am just not looking in the right places; so I want to apologize if the questions is too fundamental. But with what little example I've found from the 1.0.6-Beta distribution/samples, it wasn't very helpful for me to determine all the dependencies(and version) I need to compile a project.
The example just asked to copy every jar under lib/ and one http://community.jboss.org/community/ironjacamar IronJacamar-sjc.jar from bin directory and compile in ant; since I am restricted to maven build environment, I have to somehow enter the version information. How am I supposed to do that?
And that's just first part of my battle. Since the resources I am testing is behind the firewall from my usual development environment, I can't run *profile jbossas-remote-6;* I have to deploy to the isolated environment and somehow run my tests that way. But first I'd like to get through the hump of just setting up the libraries.
Hasn't anyone had the same task, to use maven to set up at least the compile time environment?
Thanks!

[jBPM] - Why is Timer event not triggered in J2EE container?

Hi all,
I have a timer event that is suppose to automatically trigger after 3 minutes.
When I'm testing it on standalone Java program, the bpmn works fine and the task following the timer event gets triggered.
However, the timer event just never gets triggered after I put the StatefulKnowledgeSession into a EJB on the server.
This is a portion of the timer (bpmn2)
<boundaryEvent id="_5" name="TimerEvent" attachedToRef="_4" cancelActivity="false" >
<timerEventDefinition>
<timeDuration xsi:type="tFormalExpression">180s</timeDuration>
</timerEventDefinition>
</boundaryEvent>
My stateless session EJB looks like this:
...
public class CommandDelegate implements SessionBean, ICommandDelegateLocalBM, ICommandDelegateRemoteBM {
private static StatefulKnowledgeSession stateful;
public void startProcess(String processId, Map<String, Object> parameters) {
stateful.startProcess(processId, parameters);
}
Here is my test client:
context = new InitialContext(env);
Object obj = context.lookup("ejb/CommandDelegateRemote");
remoteHome = (CommandDelegateRemoteHome)PortableRemoteObject.narrow(obj,CommandDelegateRemoteHome.class);
remote = remoteHome.create();
...
remote.startProcess("TestTimerBPMN", params);
Any ideas anyone?

[jBPM] - Advice on how to approach CRON based BPMN2 processes

Hi,
I have the need to run Processes, with no human tasks, on a repeating basis, normally 3 times a day, weekdays and excluding holidays. But I also need to run the same tasks on an ad hoc basis. So if I code a new workitem that is a Start task that uses Quartz scheduler (thus holidays can be supported) I could not run that on an ad hoc basis. Alternately I could use a normal Start task and have a diverging gateway as the first node that tests for a boolean param that represents "run now" it could diverge to a converging gateway and thus to the actual first node that does real work in the Process, the alternate path would hit the new Timer workitem that I would have to code that also used Quartz, this would then hit a converging gateway with the direct run now path to start the actual Process that does the work I need. Another alternative is theh start task with Quartz and also an integrated parameter test for pass through.
Any suggestions on how this problem scenario is best solved?
thx.
Ed

Hi guys,
I developed that process with a SubProcess (designed with the new BPMN2 editor). The xml definition is attached.

[jBPM] - event handler method not getting invoked in jbpm

Hi,
I have a spring 3 and jbpm 4.4 integration environment.
However in one of my tasks I have provided a event as per jpdl specs.
My jpdl snippet with the task element looks like this:
<task name="TK1"
assignee="test"
description="A task that gets assigned to somebody with user name test"
g="117,90,48,52">
<on event="start">
<event-handler expr="#{myEventHandler}"/>
</on>
<on event="end">
<event-handler expr="#{myEventHandler}"/>
</on>
<transition name="END" to="END" g="-31,2"/>
</task>
and the myEventHandler bean is created in spring as below:
<bean id="myEventHandler" class="com.test.MyEventHandler">
<!-- myBO bean is created in the spring application context file itself which contains code to insert/update data to DB-->
<property name="myBO" ref="myBO"/>
</bean>
and my Event handler class looks like this:
import org.jbpm.api.listener.EventListener;
import org.jbpm.api.listener.EventListenerExecution;
public class MyEventHandler implements EventListener {
private MyBO myBO;
@Override
public void notify(EventListenerExecution eventExecution) throws Exception
{
//Do some logical operation based on incoming process variable...
//Use the myBO bean to do DB operation...
myBO.insert(...);
myBO.update(...);
}
}
The problem is:
after trying several options, the notify method NEVER gets executed. I see the tasks getting created in JBPM4_TASK table, but strangely I can not get the notify() invoked. And there is no form of error or warning to be seen.
Has anybody faced similar problems?
Is there a way to resolve this?
Any help is appreciated.
