[jbpm-users] [JBoss jBPM] - exploring JBPM 4: some questions

Hi, I hope someone can help me with these problems in jbpm4 1) Referring to the example in the JBPM 4.0 Developer Guide (par 2.2. Persistent execution mode) if I try to create a processDefinition in the PVM context, then when I try to deploy it I get the following exception: [DefaultCommandService] exception while executing command org.jbpm.pvm.internal.cmd.DeployCmd@17e6a96 | java.lang.NullPointerException | at org.jbpm.pvm.internal.svc.DeploymentImpl.getFileNamesForType(DeploymentImpl.java:401) | at org.jbpm.jpdl.deploy.ParseJpdlDeployer.deploy(ParseJpdlDeployer.java:38) 2) Futhermore, if I try to execute the following code (see the example in the developer guide) EnvironmentFactory environmentFactory = new PvmEnvironmentFactory("environment.cfg.xml"); | | ProcessService processService = environmentFactory.get(ProcessService.class); | ExecutionService executionService = environmentFactory.get(ExecutionService.class); | ManagementService managementService = environmentFactory.get(ManagementService.class); | | ClientProcessDefinition processDefinition = ProcessFactory.build("loan") | .node("submit loan request").initial().behaviour(AutomaticActivity.class) | .transition().to("evaluate") | .node("evaluate").behaviour(WaitState.class) | .transition("approve").to("wire money") | .transition("reject").to("end") | .node("wire money").behaviour(AutomaticActivity.class) | .transition().to("archive") | .node("archive").behaviour(WaitState.class) | .transition().to("end") | .node("end").behaviour(WaitState.class) | .done(); | | Deployment deployment = new Deployment(processDefinition); | processService.deploy(deployment); I get other problems: - PvmEnvironmentFactory does not exist anymore - It is not possibile to use the costructor new Deployment(processDefinition) since now Deployment is an inteface. If I try using the class new DeploymentImpl(processDefinition) I get the exception showed at the point 1) 3) If I try to get a process already deployed, I could use the ProcessService.findProcessDefinitionById (or findProcessDefinitionByKey) but the ProcessDefinition do not allow me to access to the data that are available in ProcessDefinitionImpl. If I try a cast it does not work. How can I get the processDefinitionImpl (I mean the process infos such as nodes, events and so on) ? 4) is there a way to contact the developers to signal possible problems?
