It appears the problem happens with persistence enabled only. Is this a bug? Should I code something else when using persistence for timers to work properly? I'm using version 5.3. The workflow is an start event with timer event definition with a cycle of 1 second... going to a script system out hello world and then to an end event. Executing with *JPA*.... loading ksession with JPAKnowledgeService.loadStatefulKnowledgeSession( sessionId, kbase, null, env ).startProcess("testTimer"); The execution is shown below 163745 [http-8080-1] WARN bitronix.tm.twopc.Preparer - executing transaction with 0 enlisted resource Hibernate: select nextval ('hibernate_sequence') Hello World Hibernate: select processins0_.InstanceId as col_0_0_ from ProcessInstanceInfo processins0_ inner join EventTypes eventtypes1_ on processins0_.InstanceId=eventtypes1_.InstanceId where eventtypes1_.eventTypes=?

[Beginner's Corner] - Migrating from AS4 to AS7 - Property File Issue

by Neil Doshi

Neil Doshi [https://community.jboss.org/people/ndoshi] created the discussion "Migrating from AS4 to AS7 - Property File Issue" To view the discussion, visit: https://community.jboss.org/message/742858#742858 -------------------------------------------------------------- Hello, I apologize in advance if this question has already been answered. I spent some time looking around but could not find a suitable answer. Currently I am running our applications on JBoss 4.0.4 and I am trying to upgrade our systems to the latest version of JBoss AS. The problem I am running into is that our applications depend on being able to find one or more properties file during startup. The properties files hold multiple different keys that cannot be loaded individually as system properties, nor do I want to bundle them up into our war file. I would appreciate any help to point me in the right direction. --Neil -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742858#742858] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Unable to dispose ksession

by Arun Selva

Arun Selva [https://community.jboss.org/people/arselv] created the discussion "Unable to dispose ksession" To view the discussion, visit: https://community.jboss.org/message/742763#742763 -------------------------------------------------------------- My workflow process operations happens asynchronously. Creating a process instance and completing a task happens seperately. So i couldnt identify a idle time to dispose the knowledge session. Kindly help with a way to dispose the session. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742763#742763] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Event manage

by marcosdutto

marcosdutto [https://community.jboss.org/people/marcosdutto] created the discussion "Event manage" To view the discussion, visit: https://community.jboss.org/message/742843#742843 -------------------------------------------------------------- How can i do something like this? The important thing that i want to do is to activate events only in some flows of my process. Here is an example taken from the book "BPMN Modeling and Reference Guide". My events here are "Make Mortgage Offer" and "Criteria Not Met". https://community.jboss.org/servlet/JiveServlet/showImage/2-742843-18774/... https://community.jboss.org/servlet/JiveServlet/downloadImage/2-742843-18...

[jBPM] - JBPM Timers behaviour

by Bira Neto

Bira Neto [https://community.jboss.org/people/biraneto] created the discussion "JBPM Timers behaviour" To view the discussion, visit: https://community.jboss.org/message/742825#742825 -------------------------------------------------------------- What is the bahaviour for jbpm timers in a low level? Does reaching the end event in the workflow clears the timers? I also ask this because I have a workflow that has a start timer (with a cycle type and 1 min period) leading to and end event. I was expecting it to start every minute but it only do so while the end event is not reached (if I put some more flows and gateways that block the end from being reached). Is that expected behaviour or should timers fire indefinetely for such a workflow? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742825#742825] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[Performance Tuning] - Re: Connection pool problem jboss 5.1 + hibernate oracle 11.2.3.0 DB, Hibernate 3.3.2.GA

You should monitor the pool statistic and see whether the number of used connections will grow ovber the time. Also you might have a look into these: https://community.jboss.org/docs/DOC-9255 https://community.jboss.org/wiki/CanJBossTellMeWhenIDontCloseAConnection https://community.jboss.org/docs/DOC-12682 https://community.jboss.org/wiki/WhatDoesTheMessageDoYourOwnHousekeepingMean -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742201#742201] Start a new discussion in Performance Tuning at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[Beginner's Corner] - experimenting with JBoss 7 quickstart helloworld tutorial

by mperdikeas

mperdikeas [https://community.jboss.org/people/mperdikeas] created the discussion "experimenting with JBoss 7 quickstart helloworld tutorial" To view the discussion, visit: https://community.jboss.org/message/742795#742795 -------------------------------------------------------------- I am coming from a Tomcat / JSF background so I did a little experimentation with the quickstart helloworld tutorial. Specifically I was curious as to the need for the beans.xml file which basically defines namespaces. Since the first helloworld example does not include any xhtml I thought the file is not needed and so I removed it. Not surprisingly I received an error when I tried to access the deployed application: java.lang.NullPointerException org.jboss.as.quickstarts.helloworld.HelloWorldServlet.doGet(Unknown Source) javax.servlet.http.HttpServlet.service(HttpServlet.java:734) javax.servlet.http.HttpServlet.service(HttpServlet.java:847) What I cannot fathom is how not defining XML namespaces which are not used results in a NullPointerException error. If anybody can shed some light this will help me improve my mental model and perhaps be able to decipher similarly cryptic messages in the future. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742795#742795] Start a new discussion in Beginner's Corner at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - JBPM 5.3 - new editor

Roman Biesiada [https://community.jboss.org/people/rtutus] created the discussion "JBPM 5.3 - new editor" To view the discussion, visit: https://community.jboss.org/message/742781#742781 -------------------------------------------------------------- Hello, Could someone can help me to locate any documentation for new JBPM Editor introduced in jBPM 5.3? It has very nice user interface and it looks like a significant step forward but I could not find any description of the new editor except couple sentences in official jBPM 5.3 User Guide. Does anybody knows what to do to have the new editor refreshing the palette automatically so newly added service tasks (imported from repository) are shown on the pallete without need to close editor window and opening it again? thanks, Roman -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/742781#742781] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]
