Re: [jboss-user] [JBoss Web Services] - Web Service annotated with @PostConstruct - wrong order w.r.t Listener

The main job of the ServletContextListener is to grab the ServletContext so that later in the @PostConstruct init-method on the Web service, I can load some resources that are only available from the ServletContext's classloader. So far, I'm hitting 0.750 (I should be in the majors!) Here is my deployment descriptor for my 'Simple' Web service: <?xml version="1.0" encoding="UTF-8"?> <web-app xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" version="2.5"> <listener> <listener-class>_dbws.ProviderListener</listener-class> </listener> <servlet> <servlet-name>_dbws.SimpleProvider</servlet-name> <servlet-class>_dbws.SimpleProvider</servlet-class> <load-on-startup>0</load-on-startup> </servlet> <servlet-mapping> <servlet-name>_dbws.SimpleProvider</servlet-name> <url-pattern>/simple</url-pattern> </servlet-mapping> </web-app> -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/550232#550232] Start a new discussion in JBoss Web Services at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Performance Tuning] - Performance issue to use remote ejb?

To view the discussion, visit: http://community.jboss.org/message/550228#550228 -------------------------------------------------------------- 1) By reference 2) Not sure of what you are asking. If the EJB is remote, the request and response data will always have to be marshalled and transferred across the network. Is that slower than accessing a local EJB? Yes! But there is no other way to access a remote EJB. If possible, cache the EJB proxy you look up from JNDI. By reusing this proxy you will at least save time by not repeatedly making the JNDI call. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/550228#550228] Start a new discussion in Performance Tuning at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [Beginner's Corner] - Couldn't start JBoss AS as Windows service

by Peter Johnson

Peter Johnson [http://community.jboss.org/people/peterj] replied to the discussion "Couldn't start JBoss AS as Windows service" To view the discussion, visit: http://community.jboss.org/message/550226#550226 -------------------------------------------------------------- *>>Was the problem occured because i'm install jboss as 4.0.5ga but the service is version 5?* No. Look inside the service.bat file - it uses the name JBAS50SVC as the service's short name. You can edit the lines in service.bat that identify the service to be anything you like. To get to the cause of the problem, you have to look in two locations. First, go to the Windows Event Viewer and look in the Application log. That usually has something in it regarding the error. The other place to look is in C:\jboss-as-web\bin\run.log - service.bat redirects all stdout output to that file. If you don't understand the messages you see in either place, post them here. -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/550226#550226] Start a new discussion in Beginner's Corner at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - jBPM and caching

by Eivind Barstad Waaler

Eivind Barstad Waaler [http://community.jboss.org/people/eivindbw] created the discussion "jBPM and caching" To view the discussion, visit: http://community.jboss.org/message/550224#550224 -------------------------------------------------------------- Does anyone have any experience enabling Hibernate second-level caching with jBPM? Things like User, Deployment and more are practically never changed in our application, and could easily be cached to reduce the amount of database queries. I can get it to work by writing my own custom criteria searches, adding setCacheable(true), but nothing else seems to have any effect. Re-implementing the whole API just to add that one line to all criterias does not seem like a good idea. Does anyone have any hints or tips regarding this? Right now our application drowns in database requests with a few hundred active process-instances, and we need it to scale up to at least 10 000. Documentation suggests that the Deployment objects are cached, but as far as I can tell that is not happening in our application. We are using Spring to set up the SessionFactory. Could this be the problem? -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/550224#550224] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - How to overwrite fork, join and decision?

Max Bryan [http://community.jboss.org/people/MBryan] created the discussion "How to overwrite fork, join and decision?" To view the discussion, visit: http://community.jboss.org/message/550212#550212 -------------------------------------------------------------- Hey Folks, I'm working on a process with jPDL. The process definition seems right to me, but i nevertheless can't run the simulation. Is the problem, that i haven't overwritten the forks, joins and decisions? I only know how to overwrite tasks and i think, this is the problem why i can't run this simulation. Here is the code: <process-definition name="newProcess"> <swimlane name="labor"> <assignment pooled-actors="labor1,labor2,labor3"/> </swimlane> <swimlane name="doktor"> <assignment pooled-actors="doktor1,doktor2,doktor3"/> </swimlane> <start-state name="start"> <transition to="anamnese" name="start"/> </start-state> <task-node name="anamnese"> <task name="anamnese" swimlane="doktor" /> <transition to="entscheidung" name="e1"/> </task-node> <decision name="entscheidung"> <transition to="fork1" name="to fork1"></transition> </decision> <fork name="fork1"> <transition to="join1" name="join1"></transition> <transition to="blutprobe" name="blutprobe"></transition> </fork> <task-node name="blutprobe"> <task name="blutprobe" swimlane="labor"></task> <transition to="join1" name="join1"></transition> </task-node> <join name="join1"> <transition to="entscheidung1" name="entscheidung1"></transition> </join> <decision name="entschdeidung1"> <transition to="end" name="zoeliakie"></transition> </decision> <end-state name="end" /> </process-definition> <?xml version="1.0" encoding="UTF-8"?> <experiment name='newProcess' time-unit='second' run-time='16000' real-start-time='20.10.2009 08:00:00:000' currency='€' unutilized-time-cost-factor='0.0'> <scenario name="status_quo" execute="false"> <distribution name="newProcess.start" sample-type="real" type="erlang" mean="95"></distribution> <distribution name="newProcess.anamnese" sample-type="real" type="normal" mean="1800" standardDeviation="300"></distribution> <distribution name="newProcess.blutprobe" sample-type="real" type="normal" mean="1800" standardDeviation="300"></distribution> <sim-process path="/org/jbpm/sim/tutorial/business/newProcess/processdefinition.xml"> <process-overwrite start-distribution="newProcess.start"></process-overwrite> <task-overwrite task-name="anamnese" time-distribution="newProcess.anamnese"> <transition name="e1" probability="95"></transition> </task-overwrite> <task-overwrite task-name="blutprobe" time-distribution="newProcess.blutprobe"> <transition name="e1" probability="95"></transition> </task-overwrite> </sim-process> </scenario> <scenario name="status_quo_normal_case" execute="true" base-scenario="status_quo"> <resource-pool name="labor" pool-size="1" costs-per-time-unit="0.023888889"/> <resource-pool name="doktor" pool-size="1" costs-per-time-unit="0.043888889"/> <output path='./sim_out/'></output> </scenario> </experiment> Thanks in advance -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/550212#550212] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

[jBPM] - Bug in JBPM 4: timers on transitions.

Gert Leenders [http://community.jboss.org/people/glnds] created the discussion "Bug in JBPM 4: timers on transitions." To view the discussion, visit: http://community.jboss.org/message/550211#550211 -------------------------------------------------------------- Even in the last snapshot build jbpm-distro-4.4-20100618.012828-1 there still seems to be a bug when adding a timer to a transition: *<state>* * <transition to="Task x">* * <timer duedate="3 seconds"/>* * </transition>* *</state>* When defining this in jpdl you’ll always get the following error: +Exception in thread "main" org.jbpm.api.JbpmException: timer has no signalName or eventName specified+ + at org.jbpm.pvm.internal.job.TimerImpl.validate(TimerImpl.java:143)+ + at org.jbpm.pvm.internal.jobexecutor.JobExecutorTimerSession.schedule(JobExecutorTimerSession.java:53)+ + at org.jbpm.pvm.internal.job.TimerImpl.schedule(TimerImpl.java:70)+ This is because the variable ‘eventName’ of TimerImpl is never set (and there seems no possibility to do it due to the restrictions in jpdl and the jpldParser). Maybe when parsing a timer on a transition a default event (timeout) could be specified?

Re: [jboss-user] [jBPM] - How to get a list of available transitions for an ActivityExecution

by Joe Gottman

Joe Gottman [http://community.jboss.org/people/joegottman] replied to the discussion "How to get a list of available transitions for an ActivityExecution" To view the discussion, visit: http://community.jboss.org/message/550204#550204 -------------------------------------------------------------- I finally figured it out. Jorge's answer was almost correct, but I had to manually create an Environment variable for ExecutionImpl.getActivity() to succeed. So the final code was EnvironmentFactory environmentFactory = (EnvironmentFactory)processEngine; Execution execution = executionService.findExecutionById(executionID); if (execution instanceof ExecutionImpl) { ExecutionImpl executionImpl = (ExecutionImpl)execution; EnvironmentImpl environment = environmentFactory.openEnvironment(); ActivityImpl activityImpl = null; try { activityImpl = executionImpl.getActivity(); } finally { environment.close(); } if (activityImpl != null) { return activityImpl.getOutgoingTransitionsMap().keySet(); } } return Collections.<String>emptySet(); -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/550204#550204] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]

Re: [jboss-user] [jBPM] - Suggestion for transitions

by Jochen Mader

Jochen Mader [http://community.jboss.org/people/jochen_mader] replied to the discussion "Suggestion for transitions" To view the discussion, visit: http://community.jboss.org/message/550190#550190 -------------------------------------------------------------- I want to be able to signal the transition. Example: There is one user who does a couple of changes on a data item, he then either "submits" (signal execution with the string "submit") or saves the data item. When he "submits", another user will be able to "accept", "decline" or "defer" the changes with each signal triggering a different workflow. A decision for me involves some computation which has to be done inside jBPM whereas what I am doing is that a user actively triggers the different workflows. So I would say that using signalExecution is the correct way in a process sense. Thanks, Jochen -------------------------------------------------------------- Reply to this message by going to Community [http://community.jboss.org/message/550190#550190] Start a new discussion in jBPM at Community [http://community.jboss.org/choose-container!input.jspa?contentType=1&cont...]
