The problem is that I was not using transactions... Just surround my code in a tm.begin() and tm.commit() and it works fine. I get my tm using the jboss tm locator: TransactionManager tm = TransactionManagerLocator.locateTransactionManager(); tm.begin(); // get and set variables here tm.commit(); Is this the right way to go? -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/733626#733626] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[EJB3] - Re: Remote access works fine, but local injection does not – any ideas?

To view the discussion, visit: https://community.jboss.org/message/726584#726584 -------------------------------------------------------------- I have found out that this may be a class loading problem still present in JBoss 7.1.1. My problem looks very similar to what is described very well in this thread: https://community.jboss.org/thread/169828?start=0&tstart=0 https://community.jboss.org/thread/169828?start=0&tstart=0 >From that thread it looks as if the fact that I mave my business interfaces packaged with both my ejb.jar and my web.war creates a class loading problem because each jar/war has its own class loader, which effectively makes the EJB from my ejb.jar incompatible with the business interface in my web.war. Hmmm... perhaps it is time to file a bug report. -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/726584#726584] Start a new discussion in EJB3 at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - How to set the condition on a XOR Gateway using guvnor web designer

by Christian Witschel

Christian Witschel [https://community.jboss.org/people/cwitschel] created the discussion "How to set the condition on a XOR Gateway using guvnor web designer" To view the discussion, visit: https://community.jboss.org/message/754991#754991 -------------------------------------------------------------- Dear All, Either I am blind folded or guvnor lacks the possibility to use XOR Gateways effectively. 1. I am adding a XOR (Data-based exclusive (XOR) Gateway as its called). 2. in the properties I give it the Name: approval successfull? 3. Add one incomming connection and 2 outgoing (one labelled yes the other no) There is a process variable [approval] of type boolean. this is set in the preceeding user task. All this was done in jBPM 5.3s Guvnor, jBPM Designer Web 2.3 Release version. How do I make the XOR use the process variable [approval]? Please dont tell me it can only be done with the eclipse plugin. Cheers -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/754991#754991] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - jBPM 5.4 released !

by Kris Verlaenen

Kris Verlaenen [https://community.jboss.org/people/KrisVerlaenen] created the discussion "jBPM 5.4 released !" To view the discussion, visit: https://community.jboss.org/message/778581#778581 -------------------------------------------------------------- http://kverlaen.blogspot.be/2012/11/jbpm-54-released.html http://kverlaen.blogspot.be/2012/11/jbpm-54-released.html We are proud to announce the release of *jBPM 5.4.0.Final*. The bits were ready more than a week ago already (and looking at the download statistics quite a few of you already found them ;)), but a busy travel schedule made it difficult to complete the work and announce everything. But here it is ! *Downloads*: https://sourceforge.net/projects/jbpm/files/jBPM%205/jbpm-5.4.0.Final/ https://sourceforge.net/projects/jbpm/files/jBPM%205/jbpm-5.4.0.Final/ *Documentation*: http://docs.jboss.org/jbpm/v5.4/userguide/ http://docs.jboss.org/jbpm/v5.4/userguide/ *API and JavaDocs*: http://docs.jboss.org/jbpm/v5.4/javadocs/ http://docs.jboss.org/jbpm/v5.4/javadocs/ The +jBPM installer+ is probably the best way to get started. Download the http://sourceforge.net/projects/jbpm/files/jBPM%205/jbpm-5.4.0.Final/jbpm... full installer and follow the documentation http://docs.jboss.org/jbpm/v5.4/userguide/ch.installer.html here to walk through some of the most important components. So what's new? *Simulation* We've added simulation capabilities to the web-based process designer, that allows you to simulate how a process might behave at runtime. This includes the addition of various simulation-related properties (like resources and duration-related attributes for tasks, and probabilities for diverging gateways etc.). Our implementation is based on the specification created by the http://code.google.com/p/bpswg/ BPSWG (Business Process Simulation Working Group). Based on these properties, you can run a number of instances of your process and: * Use the path finder to look at all identified paths * Look at the generated charts containing information about minimal, maximum and average completion times, etc. using (horizontal and vertical barcharts, pie charts or tables. * Check the timeline to get an overview of all the recorded events Maciej did a http://mswiderski.blogspot.be/2012/08/simulation-in-jbpm-draft.html blog recently on the ideas and concepts behind it, and Tihomir did a http://surdilovic.wordpress.com/2012/09/13/business-process-simulation-in... blog, including a 12-minute video, that shows simulation in action. *Local task service* When human actors participate in a business process (also known as human workflow), a task service is used to manage the life cycle of the tasks (claiming, completing, task lists, etc.). While we supported the use of a centralized task service (using HornetQ for remoting), we now also support a +local+ version that runs as a simple Java component next to the engine and all the work it does is synchronous and nicely integrated with the transaction of the process engine. org.jbpm.task.service.TaskService taskService = new org.jbpm.task.service.TaskService( emf, SystemEventListenerFactory.getSystemEventListener()); LocalTaskService localTaskService = new LocalTaskService(taskService); LocalHTWorkItemHandler humanTaskHandler = new LocalHTWorkItemHandler( localTaskService, ksession, OnErrorAction.RETHROW); humanTaskHandler.connect(); ksession.getWorkItemManager().registerWorkItemHandler( "Human Task", humanTaskHandler); *Spring* We have improved our http://docs.jboss.org/jbpm/v5.4/userguide/ch.integration.html#d0e7839 Spring support, where you can use a Spring configuration file to configure your environment and inject a ksession and/or task service into your application code. For transactions, it integrates with the Spring transaction manager, supporting both JTA and RESOURCE_LOCAL with shared entity manager factory (emf) or shared entity manager (em). *JPA2* jBPM runtime persistence can now also use JPA2 for persistence. That means it is completely independent of the underlying persistence provider (we use Hibernate by default but other persistence providers should be possible as well). You can use Hibernate4 with JPA2 for even better performance. For all the details on how to do this, here's a link to a persistence configuration file for both https://github.com/droolsjbpm/jbpm/blob/master/jbpm-installer/db/jbpm-per... JPA1 and https://github.com/droolsjbpm/jbpm/blob/master/jbpm-installer/db/jbpm-per... JPA2. *Some of the other features* * Improvements on some of the BPMN 2.0 constructs in the core engine, related to error events, terminating end events in sub processes, * Introduction of a business calendar related to timers etc. * The ability to start a process by name, which will automatically start the latest version of that process. * We created separate wars for EE6 (AS7) and EE5 (AS5) to avoid a lot of manual dependency management. JBoss AS 7.1.1 is now the new default application server in the installer. * Improved support for invoking web services from inside your processes. * A database-backed solution for managing which users are part of which group (UserGroupCallback). * When configuring handlers for domain-specific services, the ksession is automatically injected as an optional constructor parameter in the handler configuration file. The details on all fixed issues and new features can be found in detail in https://issues.jboss.org/browse/JBPM JIRA. jBPM 5.4.0.Final has been released in sync with the latest http://blog.athico.com/2012/11/drools-550final-released.html Drools 5.5.0.Final release. If you have any questions / issues, let us know: * Ask questions on IRC: chat.freenode.net:6667 #jbpm (there is a web-based client available http://webchat.freenode.net/ here) * Create a JIRA issue: https://issues.jboss.org/browse/JBPM https://issues.jboss.org/browse/JBPM * Ask the community in the https://community.jboss.org/community/jbpm?view=discussions forum The jBPM team -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/778581#778581] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - Exception handling for technical exceptions

by M S

M S [https://community.jboss.org/people/marcomr] created the discussion "Exception handling for technical exceptions" To view the discussion, visit: https://community.jboss.org/message/743088#743088 -------------------------------------------------------------- Hello. I have a scenario where a java exception inside a work item handler should abort the workflow execution. Up until now I've been mapping this java exception to a business exception (following a suggestion by Kris in which I map the exception as an exit variable and signal from an exit action if said variable is filled) but I'd like to hide this complexity from the modellers: they should know that a service task could abort the workflow and not have to model error events for this. I see that older jBPM versions had the concept of a global exception handler. Is there any similar concept in 5.3? What is the best approach to handle this scenario?

[jBPM] - Integrating jBPM 5 into web application - architecture

by Pedro Gonçalves

Pedro Gonçalves [https://community.jboss.org/people/pgoncalves] created the discussion "Integrating jBPM 5 into web application - architecture" To view the discussion, visit: https://community.jboss.org/message/736299#736299 -------------------------------------------------------------- Hello, I've been trying to integrate the jBPM5 into my own web app, but I've some doubts about how to make it. My processes are mostly composed by Human Actions, which make them long running processes. My problem is similar to the one discribed here: https://community.jboss.org/message/636561#636561 https://community.jboss.org/message/636561#636561 I've already configured jBPM to use persistense and I was able to start processes (building kbase, ksession, taskService, etc.). But everytime I start a process, or try to list the started processes I create a new entry on SessionInfo (in the database), and I got a empty list of started processes (I've 2 process instances holding a human action). * It is clear to me that I'm not managing the sessions properly, my question is, what is the best way to do it? :p * Does jBPM5.3 brings any improvement on this? * What are the best practices regarding the use of the kbase, ksessions, taskServices, etc. Thanks in advance! -------------------------------------------------------------- Reply to this message by going to Community [https://community.jboss.org/message/736299#736299] Start a new discussion in jBPM at Community [https://community.jboss.org/choose-container!input.jspa?contentType=1&con...]

[jBPM] - JBPM 5.2 console can't get any Guvnor Process Definition

by Rogelio Di Pasquale

Rogelio Di Pasquale [https://community.jboss.org/people/roger0681] created the discussion "JBPM 5.2 console can't get any Guvnor Process Definition" To view the discussion, visit: https://community.jboss.org/message/646993#646993 -------------------------------------------------------------- I'm using jbpm-5.2.0.Final jbpm-5.2.0.Final-gwt-console guvnor-distribution-wars-5.3.1.Final on jboss-as-7.0.1 I could create process definitions in Eclipse, add them to Guvnor, build the package, create snapshots, etc. But when trying to see process definitions in jbpm-console, I just see nothing. If I try using the rest api ( http://127.0.0.1:8080/gwt-console-server/rs/process/definitions http://127.0.0.1:8080/gwt-console-server/rs/process/definitions), I get: {"definitions":[]} (and JBoss logs says that parsed 0 process definitions). I've made several packages in Guvnor, and jbpm-console seems to be trying to parse processes from all of them, but keeps saying he got 0 processes to parse. Here I upload a list of assets obtained from the Guvnor's rest api ( http://127.0.0.1:8080/drools-guvnor/rest/packages/defaultPackage/assets http://127.0.0.1:8080/drools-guvnor/rest/packages/defaultPackage/assets). Should jbpm-console see any process? What does a process definition look like in the rest API when it is parseable by jbpm-console?
