    How to start a process (developed in BPMN2 Modeler) in a CDI application based on jBPM 6.2?

    Michael Awizen Novice

      Hi everybody,

       

      I developed a process using the BPMN2 Modeler.

      The process file is used in the RuntimeEnvironment producer as suggested in the documentation http://docs.jboss.org/jbpm/v6.2/userguide/jBPMIntegration.html#d0e19365

       

      The process is tested in a test class and it works.

       

      Now I try to start the process in the CDI application like this:

       

      KModuleDeploymentUnit deploymentUnit = new KModuleDeploymentUnit("myGroupId", "myArtifactId", "1.0");
      deploymentService.deploy(deploymentUnit);
      
      Map<String, Object> params = new HashMap<String, Object>();
      params.put("potentialOwner", "userA");
      long processInstanceId = processService.startProcess(deploymentUnit.getIdentifier(), "mySimpleProcess", params);
      

       

      Unfortunately this does not work:

      org.eclipse.aether.resolution.ArtifactResolutionException: Could not find artifact myGroupId:myArtifactId:jar:1.0 in central (http://repo1.maven.org/maven2/)

       

      My question is:

       

      How to start a process modelled with the "BPMN2 Modeler" using the CDI service?

          Michael,

           

          The RuntimeEnvironment producer is mainly for pre 6.2 environments. The recommended approach in 6.2 is to package your process as a kjar in maven. This page and accompanying 6.2 examples are a good reference examples (Upgrade of jbpm-6-examples to jBPM 6.2 services | Jiri Svitak). The StartupBean in his examples replaces the EnvironmentProducer for deploying services.

           

          Once your process is packaged as a kjar, then your first two lines should find the artifact and deploy it correctly.

            Hi Chris,

             

            thank you for your suggestion.

             

            OK then. I will package my process as kjar and install it to my local maven.

             

            I have created my process with BPMN2 Modeler.

             

            How to package a process definition as kjar?

             

            I miss this crucial information in the 6.2 documentation.

              Many thanks to Chris and Francesco

               

              Deploying a kjar is not that difficult...

               

              To work with my process definition file as desired I have placed it in a separate minimal maven project.

               

              The most important thing is to add those lines to the pom of the new project:

               

              <packaging>kjar</packaging>
              
              <properties>
              <jbpm.version>6.2.0.Final</jbpm.version>
              </properties>
              
              <build>
              <plugins>
                <plugin>
                  <groupId>org.kie</groupId>
                  <artifactId>kie-maven-plugin</artifactId>
                <version>${jbpm.version}</version>
                  <extensions>true</extensions>
                </plugin>
              </plugins>
              </build>
              

               

              Eclipse complains about the plugin line, but installing of the kjar to maven works anyway.

               

              Now I can design my process using BPMN2 Modeller in my Luna Eclipse.

               

              Deployment with KModuleDeploymentUnit works as desired.

               

               

              KModuleDeploymentUnit deploymentUnit = new KModuleDeploymentUnit("com.sample", "myProcess", "1.0");
              deploymentService.deploy(deploymentUnit);
              
              Map<String, Object> params = new HashMap<String, Object>();
              params.put("potentialOwner", "userA");
              long processInstanceId = processService.startProcess(deploymentUnit.getIdentifier(), "myProcessId", params);
              

               

               

              As a next step I will move the deployment lines to the StartupBean.

               

              Enclosed see my minimal project for process deployment.
