    Spring 3 + jbpm 4.4 + hibernate 3.3 + JPA + JTA integration error.

    Ayusman Dikshit Newbie

      All,

      I have been able to make some progress in terms of integrating my current project with jbpm, based on the link below:

       

      http://captaincaveman.posterous.com/jbpm-43-spring-3-jboss-jpa-jta-configuration

       

      With minor modifications, the set up was pretty much close. However, after all the configuration changes are done, I do face this error during server start-up.

      I do have the jbpm.jar file in the classpath (it's in the WEB-INF\lib folder.)

       

      This is bit of a suprise to me. Has anybody faced similar problem?

       

      System configuration:

      RAD 7.5 and WAS 7.0.0.15 Test Environment on Windows XP SP3.

      DB server: SQL Server.

       

      I added the following to my already working spring applicationContext.xml file:

       

           <!-- Added for JBPM  START -->
           <!--
              Activates a load-time weaver for the context. Any bean within the context that
              implements LoadTimeWeaverAware (such as LocalContainerEntityManagerFactoryBean)
              will receive a reference to the auto-detected load-time weaver.
           -->
          <!--    <context:load-time-weaver aspectj-weaving="on" />-->
          
          <!--
              Turn on AspectJ @Configurable support. As a result, any time you
              instantiate an object, Spring will attempt to perform dependency
              injection on that object. This occurs for instantiation via the "new"
              keyword, as well as via reflection. This is possible because AspectJ
              is used to "weave" Roo-based applications at compile time. In effect
              this feature allows dependency injection of any object at all in your
              system, which is a very useful feature (without @Configurable you'd
              only be able to dependency inject objects acquired from Spring or
              subsequently presented to a specific Spring dependency injection
              method). Roo applications use this useful feature in a number of
              areas, such as @PersistenceContext injection into entities.
          -->
          <context:spring-configured />   
          <!--
              This declaration will cause Spring to locate every @Component,
              @Repository and @Service in your application. In practical terms this
              allows you to write a POJO and then simply annotate the new POJO as an
              @Service and Spring will automatically detect, instantiate and
              dependency inject your service at startup time. Importantly, you can
              then also have your new service injected into any other class that
              requires it simply by declaring a field for your service inside the
              relying class and Spring will inject it. Furthermore, this turns on
              @Autowired, @PostConstruct etc support. These annotations allow you to
              use common Spring and Java Enterprise Edition annotations in your
              classes without needing to do any special configuration. The most
              commonly used annotation is @Autowired, which instructs Spring to
              dependency inject an object into your class.

       Also...
       
       I just wanted to do the following with in the web-application.. to verify that I atleast have the handle to jbpm from with in spring...
       
       
      @Autowired
      private static ProcessEngine processEngine;
      .
      .
      . 
      .
      .
      public void foo()
      {
         
      log.debug("START jbpm processing...");
      if (null != processEngine )
      {
          RepositoryService rs = processEngine.getRepositoryService();
          ExecutionService es = processEngine.getExecutionService();
          TaskService taskService = processEngine.getTaskService();
          DeploymentQuery dq = rs.createDeploymentQuery();
          log.debug("Deployment count: "+dq.count());
          ProcessInstanceQuery piq = es.createProcessInstanceQuery();
          log.debug("Total number of process instances is: "+ piq.count());
      }
      else
      {
         log.error("Process engine object is null");
      }
      log.debug("END jbpm processing...");     
       
      }
      
          
      
       
       just incase it matters
