    Integration problem of jBPM 4, Spring and Hibernate

    keith wong Newbie


      I would like to integrate Spring and jBPM 4 (with Hibernate) but find the following problems. Can anybody help to indicate what is wrong? Or are there any working example which demonstrate how to do the integration?


      The problem is:

      Program:
      *******************************************
      import org.jbpm.pvm.internal.cfg.JbpmConfiguration;
      import org.jbpm.pvm.internal.env.Environment;
      import org.jbpm.pvm.internal.env.EnvironmentFactory;
      import org.jbpm.pvm.internal.env.PvmEnvironment;
      import org.jbpm.pvm.internal.env.SpringContext;
      import org.springframework.context.ApplicationContext;
      import org.springframework.context.support.ClassPathXmlApplicationContext;

      import Service.ProductManager;


      public class Test{

      private static ProductManager pm;

      public static void main(String args[]){
      ApplicationContext ac = new ClassPathXmlApplicationContext(new String[] {"applicationContext-test.xml"});
      EnvironmentFactory environmentFactory = (EnvironmentFactory) new PvmEnvironment(new JbpmConfiguration());
      Environment environment = environmentFactory.openEnvironment();
      environment.setContext(new SpringContext(ac));
      }

      }

      Console output:

            It says there is a ClassNotFoundException. How are you adding jbpm to the classpath? Are you sure it is there?

            • 3. Re: Integration problem of jBPM 4, Spring and Hibernate
              Shekhar Vemuri Newbie

              OK, looked closer, try this:

              <bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration">
               <constructor-arg value="taskengine.jbpm.cfg.xml"/>
               </bean>
              


              • 4. Re: Integration problem of jBPM 4, Spring and Hibernate
                Shekhar Vemuri Newbie

                or this:

                <bean id="jbpmConfiguration" class="org.jbpm.pvm.internal.cfg.SpringConfiguration">
                 <constructor-arg value="jbpm.cfg.xml"/>
                 </bean>

                  Thank you for your help! However, other problems come out......

                  Do you have any working example or tutorial recommended to me? I want to learn how to integrate JBPM4, Spring and Hibernate. However, I cannot find any example which can guide me through the whole process.

                  Now I am facing this problem:
                  How to call Spring beans from a JBPM4 process? Should I create an 'environment' variable to access Spring bean?

                  The following is my code:

                  import org.jbpm.api.Configuration;
                  import org.jbpm.api.ExecutionService;
                  import org.jbpm.api.HistoryService;
                  import org.jbpm.api.ManagementService;
                  import org.jbpm.api.NewDeployment;
                  import org.jbpm.api.ProcessEngine;
                  import org.jbpm.api.ProcessInstance;
                  import org.jbpm.api.RepositoryService;
                  import org.jbpm.api.TaskService;
                  import org.jbpm.pvm.internal.env.EnvironmentFactory;
                  import org.jbpm.pvm.internal.env.SpringContext;
                  import org.springframework.beans.BeansException;

                   Test test = new Test();
                   test.startUpJBPM();
                   //EnvironmentFactory environmentFactory = new PvmEnvironmentFactory("environment.cfg.xml");
                   environment.setContext(new SpringContext(ac)); <=== Not sure how to create and use 'environment'
                   }
                  
                   public void startUpJBPM(){
                   ProcessEngine processEngine = new Configuration().buildProcessEngine();
                   RepositoryService repositoryService = processEngine.getRepositoryService();
                   ExecutionService executionService = processEngine.getExecutionService();

                   nd.addResourceFromClasspath("jpdl/process.jpdl.xml").deploy();
                   ProcessInstance processInstance = executionService.startProcessInstanceByKey("process");
                   }
                  
                   public void createProduct(){
                   System.out.println("==== createProduct===");
                   managerProduct= (ProductManager) ac.getBean("productManager");

                  }
                  


                  Please help to indicate what is wrong.

                    Now I am facing this problem:

                    The jbpm and spring integration is well documented in the jBPM Developer Guide now, check it out first. http://docs.jboss.com/jbpm/v4.0/devguide/html_single/#springIntegration

                    To access spring bean in jbpm scope, I think you could try the code below:
                    Environment env = Environment.getCurrent();
                    SpringContext sc = env.get(SpringContext.class);
                    sc.get("your spring bean name");

                      another tip, you can find a demo about spring jbpm4 integration on Andries Inze's blog post:

                        Thanks for pointing this out, like others before you did (in other posts)

                        Makes you wonder if it really is difficult to do something like this in google: http://www.google.nl/search?q=spring+jbpm+4+integration. Results in 10 hits of which 5 are certainly relevant.

                          I follow exactly as JBPM Developers Guide session "16.3 Usage" to setup related XML. However, still cannot find the Spring Bean (my case is "TestCon" ).

                                Try add spring to the read context of script manager

                                 <script-manager default-expression-language="juel" default-script-language="juel"
                                 read-contexts="execution, environment, process-engine, spring" write-context="">
                                 <script-language name="juel" factory="org.jbpm.pvm.internal.script.JuelScriptEngineFactory" />
                                 </script-manager>

                                  The method startUpJBPM() is totally unnecessary, since the processEngine and services should have been built by SpringConfiguration bean.

                                  To deploy your process, you could get the repositoryService from spring context:

                                  RepositoryService repositoryService = ac.getBean("repositoryService");
                                  repositoryService.createDeployment().addResourceFromClasspath("jpdl/process.jpdl.xml").deploy();

                                    It was the same result that cannot find property TestCon. Do you have any sugguestion? Besides, I don't understand the meaning and possible values of the parameters of read-contexts. Are there any documents and suggested reading for this?
