[rules-users] Drools Gunvor and Oryx integration

[Patricia Bogoevici]

Hi,


I followed the steps provided but the Evaluation.bpmn file does not load correctly into the Oryx editor. Looking into the logs, it seems like Oryx complains because the BPMN schema  namespace is different from what it expects. While Drools is using this: http://www.omg.org/spec/BPMN/20100524, Oryx editor is expecting this: http://schema.omg.org/spec/BPMN/2.0.

Stack trace snippet:
ERROR [STDERR] javax.xml.bind.UnmarshalException: unexpected element (uri:"http://www.omg.org/spec/BPMN/20100524/MODEL", local:"definitions"). Expected elements are <{http://schema.omg.org/spec/BPMN/2.0}activityResource>,<{http://bpmndi.org}activityShape>,<{http://schema.omg.org/spec/BPMN/2.0}adHocSubProcess>
……


I changed the BPMN 2.0 schema for Evaluation.bpmn to match the one the designer expects, and imported the file manually into the designer (localhost:8080/designer/editor), to check if that fixed the problem. And it seems that fixed it, although, now I got a different error: 

2010-08-06 02:29:55,482 ERROR [STDERR] java.lang.IndexOutOfBoundsException: Index: 0, Size: 0

……


What I changed to Evaluation.bpmn was the root element which is now:

<definitions id="Definition"
             targetNamespace="http://www.jboss.org/drools"
             typeLanguage="http://www.java.com/javaTypes"
             expressionLanguage="http://www.mvel.org/2.0"
             xmlns="http://schema.omg.org/spec/BPMN/2.0"
             xmlns:xs="http://www.w3.org/2001/XMLSchema-instance"
             xs:schemaLocation="http://schema.omg.org/spec/BPMN/2.0 BPMN20.xsd"
             xmlns:g="http://www.jboss.org/drools/flow/gpd"
             xmlns:tns="http://www.jboss.org/drools">


I will download the source code for the designer, and try to debug this 
issue, but I wonder if any of you know what this problem is about and 
can advise on what to do next.

Thanks,
Patricia

      Hi,
       
      Just for information.
       
      In order for the Oryx integration to work, you need to
        install the oryx designer available from
      http://anonsvn.jboss.org/repos/labs/labs/jbossrules/contrib/designer/
    
    I would add that the .war is provided by the Antoine Toulme, who
    maintains a branch at github, with the aim of merging changes back
    into the main oryx tree, and you can get the latest version there:

    http://github.com/atoulme

    http://github.com/intalio/process-designer/

    

    

    
       
      Install the designer.war into JBoss and make sure you can
        access it from localhost:8080/designer
       
      Then, in the download drools-5.1.0.CR1-install.zip, you
        should see a Evaluation.bpmn

        Copy this file into your Guvnor repository through WebDAV into
        the defaultPackage (note : not any other package)
      Once you have done this, you should see the process under the
        defaultPackage Processes in Guvnor.
      And when you double click on it, you should have the bpm
        loaded in the designer.
       
      A side note is that the designer will only load bpmn file,
        for obvious reason that the rf format is not supported by oryx.
      So, you cannot create a process from Guvnor and load it in
        the designer because the default type is rf.
       
      Hope this helps.

                Hi all,

                  

                  I found a preview of the Guvnor /Oryx integration here
                  (http://blog.athico.com/2010/06/browser-based-bpmn2-authoring-in-drools.html).

                  

                  I tried Drools Guvnor 5.1.0.CR1, but there is nothing
                  about this integration, one can only view the flow
                  diagram. 

                  

                  Can any of you tell when the integration with Oryx
                  will be available for testing? Someone commented to
                  the blog entry, that it'll be for 5.1 version, but as
                  I said, it is not on 5.1.0.CR1. 

                  

                  Thanks,

                  Patricia
