What are you trying to achieve with that? What is your business scenario?

[jBPM] - ProcessEventListener methods executed twice

by Sebastien Lelarge

Sebastien Lelarge [http://community.jboss.org/people/slelarge] created the discussion "ProcessEventListener methods executed twice" To view the discussion, visit: http://community.jboss.org/message/632356#632356 -------------------------------------------------------------- Hi, I am playing with ProcessEventListener implementation and I have the feeling that methods are executed twice for the same Node. For now, I am just tracing a message when a method is triggered and I get it twice in the log file ! My goal is to fire rules when I reach a Rule Task Node because I have issues if I fireAllRules at process startup... What's wrong ? Here's how I initialize the ksession {code} ksession = JPAKnowledgeService.newStatefulKnowledgeSession(base, kconfig, JPAWorkingMemoryDbLogger wkfLogger = new JPAWorkingMemoryDbLogger(ksession); ksession.getWorkItemManager().registerWorkItemHandler("Human Task", new CommandBasedWSHumanTaskHandler(ksession)); ksession.addEventListener(new JbpmProcessEventListener(ksession)); {code} here's the code of my EventListener: {code} import org.drools.event.process.ProcessCompletedEvent; import org.drools.event.process.ProcessEventListener; import org.drools.event.process.ProcessNodeLeftEvent; import org.drools.event.process.ProcessNodeTriggeredEvent; import org.drools.event.process.ProcessStartedEvent; import org.drools.event.process.ProcessVariableChangedEvent; import org.drools.runtime.StatefulKnowledgeSession; import org.jbpm.workflow.core.node.RuleSetNode; import org.slf4j.Logger; import org.slf4j.LoggerFactory; public class JbpmProcessEventListener implements ProcessEventListener { private StatefulKnowledgeSession session; private static Logger logger = LoggerFactory.getLogger(JbpmProcessEventListener.class); public JbpmProcessEventListener(StatefulKnowledgeSession ksession){ session = ksession; } public void beforeVariableChanged(ProcessVariableChangedEvent event) { } public void beforeProcessStarted(ProcessStartedEvent event) { } public void beforeProcessCompleted(ProcessCompletedEvent event) { } public void beforeNodeTriggered(ProcessNodeTriggeredEvent event) { logger.debug("beforeNodeTriggered: " + event.getNodeInstance().getNode().getClass()); logger.debug("beforeNodeTriggered: " + event.getNodeInstance().getNode().getName()); if (event.getNodeInstance().getNode() instanceof RuleSetNode) { session.fireAllRules(); } } public void beforeNodeLeft(ProcessNodeLeftEvent event) { } public void afterVariableChanged(ProcessVariableChangedEvent event) { } public void afterProcessStarted(ProcessStartedEvent event) { } public void afterProcessCompleted(ProcessCompletedEvent event) { } public void afterNodeTriggered(ProcessNodeTriggeredEvent event) { } public void afterNodeLeft(ProcessNodeLeftEvent event) { } } {code} -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632356#632356] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - Loss of Constraint Code on Component Insertion

by ksolveson

ksolveson [http://community.jboss.org/people/ksolveson] created the discussion "Loss of Constraint Code on Component Insertion" To view the discussion, visit: http://community.jboss.org/message/632315#632315 -------------------------------------------------------------- I'm new to jBPM (just downloaded 5.1.0.final a few days ago) and have run into a small frustration. Whenever I try to insert a Component (e.g. a Script Task) after a Diverging Gateway, the Java code that defines the associated Diverging Gateway Constraint disappears. I've tried a number of different combinations, e.g. inserting the Component and then moving the Sequence Flow arrow, deleting the arrow and then inserting the new Component, but nothing seems to work. There doesn't seem to be any way of inserting a new Component without losing the Java code associated with the Constraint in question. Any ideas anybody? Thanks in advance. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632315#632315] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - Can be jBPM used for dynamic orchestration of WebServices?

To view the discussion, visit: http://community.jboss.org/message/632217#632217 -------------------------------------------------------------- I need some engine which would allow me to generate web service orchestration during runtime - a user logs in and series of tasks is generated for him. Example: I have three WS method - GET, POST, DELETE and I want to call them in the defined order but each user would have different order. And I want the order to be generated automatically from a XML file or something like that. If it's not understandable, I can explained in a different way. Is this possible with jBPM? Any help would be appreciated. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632217#632217] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[JBoss Messaging] - Re: JBoss JMS standalone GUI tool for beginners showing queues and messages

by Fred Weers

Fred Weers [http://community.jboss.org/people/frederikw] created the discussion "Re: JBoss JMS standalone GUI tool for beginners showing queues and messages" To view the discussion, visit: http://community.jboss.org/message/632214#632214 -------------------------------------------------------------- Hello Gaurav, the tool includes libraries from JBoss 5 (see the lib-directory). If you use JBoss 4, you should probably replace those libraries. But I don't know if the source code will then compile (JBoss 5 classes used in the tool may not exist in JBoss 4). The error appears to originate in ServerQueueMon.java on the line fireTableRowsUpdated(0, getRowCount()-1); You can replace that with fireTableDataChanged(); But that will probably not remove the cause of the error. Most of the data that the tool displays is retrieved using methods in JmsUtil.java Try calling these methods from a test program. E.g. if JmsUtil.getQueueNames(InitialContext) returns an empty list, you probably found the cause of the problems. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/632214#632214] Start a new discussion in JBoss Messaging at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
