[Installation, Configuration & Deployment] - Classloader bug with java2parentdelegation in JBoss 5.x?
by ops
Hi,
I tested the following using JBoss 4.2.2.GA. I deployed some utility classes in server/default/lib and also in my application configured with java2parentdelegation=true. The application has a scoped loader repository. In fact, the classes stored in lib are only used, if they were loaded to the default UnifiedLoaderRepository before. This behaviour is exactly as described in the classloader wiki. BUT! If I test the same szenario with JBoss 5.1.0.GA, there is a strage thing happening: If the class was not loaded to the standard UnifiedLoaderRepository before, it is loaded into it now and used.
If I understood the class loading model right, this is a contradiction to the java2parentdelegation flag, wich means that classes from the standard repository are only used in scoped applications, if they were loaded to the standard repository before. In any other case the scoped application has to load the classes itself.
What do you experts think?

Is this good enogh? Sorry for previous post, this forum has very nice feature - you can not edit or remove post once you have submitted it. So, if you submit something by mistake, no way to fix it.

This probably is the cause. Thank for the answer. Too bad they did not use standard way of log in to application (like in gwt-console-server-jbpm where it is easy to customize), but they own approach, which makes customization hard to people not familiar with gwt.

[jBPM Users] - Re: Problem with node state
by mafemuea
Hello
I post more information about my problem:
I use jBPM 3.2.6.
This is a part of workflow:
| .....
| <task-node name="Recepcion de catalogos">
| <description>
| RecepciÃÂón de catÃÂálogos
| </description>
| <task name="Recepcionar catalogos">
| <description>
| recepcionarCatalogos.do
| </description>
| <assignment class="*.*.*.bussiness.jbpm.handler.assignment.AsignaPoolActorTarea"></assignment>
| </task>
| <transition to="Esperar para desmontar"></transition>
| </task-node>
| <state name="Esperar para desmontar">
| <event type="node-enter">
| <action name="Esperar para desmontar" class="*.*.*.bussiness.jbpm.handler.action.ConfigurarPlanificadorDesmontaje"></action>
| </event>
| <transition to="Valor mayor 500 mil"></transition>
| </state>
| <decision name="Valor mayor 500 mil">
| <handler class="*.*.*.bussiness.jbpm.handler.decision.ValorMayor500milEuros"></handler>
| <transition to="Solicitud desmontaje" name="No"></transition>
| <transition to="Solicitud de escolta desmontaje" name="Si"></transition>
| </decision>
| .....
|
The handler class "ConfigurarPlanificadorDesmontaje":
| public void execute(ExecutionContext executionContext) throws Exception {
| try{
| logger.debug("[execute] Inicio");
| BusinessCalendar businessCalendar = new BusinessCalendar();
| Token token = executionContext.getToken();
| logger.debug("[execute] token name: " + executionContext.getToken());
| Timer timer = new Timer (token);
| timer.setName("TimerDesmontaje");
|
| Delegation delegation = new Delegation("*.*.*.bussiness.jbpm.handler.action.SalirPlanificadorDesmontaje");
| executionContext.getJbpmContext().getSession().save(delegation);
|
| Action action = new Action ();
| action.setName("Salir de planificador");
| action.setActionDelegation(delegation);
| timer.setAction(action);
| timer.setGraphElement(executionContext.getNode());
|
| String tiempo = "2 business minutes"; //TODO: Value dinamic, go to BD
| Duration duration = new Duration(tiempo);
| Date dueDateDate = businessCalendar.add(new Date(), duration);
| timer.setDueDate(dueDateDate);
|
| SchedulerService schedulerService = (SchedulerService) Services.getCurrentService(Services.SERVICENAME_SCHEDULER);
| schedulerService.createTimer(timer);
| logger.debug("[execute] Fin");
| }catch(Exception e){
| throw e;
| }
| }
|
|
And the handler class "SalirPlanificadorDesmontaje":
| public void execute(ExecutionContext context) throws Exception {
| try{
| logger.debug("[execute] Inicio");
|
| context.leaveNode();
| logger.debug("[execute] Fin");
| }catch (Exception e) {
| throw e;
| }
| }
|
When it finish the task "Recepcion de catalogos", my workflow should wait time (String tiempo = "2 business minutes"; //TODO: Value dinamic, go to BD) before running the decision node "Valor mayor 500 mil", but happend the error:

I have no clue how it is done in JBoss because I am using Tomcat. The Tomcat demo setup (jBPM-4.1) has this lines in the server.xml to reference the jBPM users' database. I don't know how JbpmConsoleRealm is implemented.

| <Realm className="org.jbpm.integration.tomcat6.JbpmConsoleRealm"
| driverName="org.hsqldb.jdbcDriver"

| connectionPassword="" />
|
| </Host>
| </Engine>

It could be that the console does not use the custom IdentitySession since the BPM-console is not jused used exclusively for jBPM. Maybe you should ask about this in the BPM-Console forum.
P.S.: Please quote me correctly next time. :)
