jBPM 5.2 issue Jboss7.1Beta

pushpak1981 Jan 13, 2012 4:18 AM

We have setup jBPM5.2 on JBoss7.1Beta when we try to execute sample business process we get the following error.

Caused by: java.lang.IllegalAccessException: Class org.mvel2.optimizers.impl.refl.ReflectiveAccessorOptimizer can not access a member of class org.jboss.stdio.StdioContext$DelegatingPrintStream with modifiers "public"

Below is the sample bpmn we are trying to deploy:

Are we missing any configuration for JBoss7 ?

we have the same problem, with this code snip.

	try {
	InitialContext ctx= new InitialContext();
	kbi=(KnowledgeBaseInterface)ctx.lookup("java:global/examplejbpm5/KnowledgeBaseEJB!it.comp.example.jbpm5.KnowledgeBaseInterface");
	} catch (NamingException e) {
	// TODO Auto-generated catch block
	e.printStackTrace();
	}

KnowledgeBase kbase= kbi.getKB();

	EntityManagerFactory emf = Persistence.createEntityManagerFactory("it.comp.example.jbpm5.jpa");
	Environment env = KnowledgeBaseFactory.newEnvironment();
	env.set(EnvironmentName.ENTITY_MANAGER_FACTORY, emf);

	StatefulKnowledgeSession ksession = JPAKnowledgeService.newStatefulKnowledgeSession(kbase, null, env);
	ProcessInstance pi = ksession.getProcessInstance(1);
	if (pi == null) {
	Map<String, Object> params = new HashMap<String, Object>();
	params.put("employee", "krisv");
	params.put("reason", "Yearly performance evaluation");
	pi = ksession.startProcess("sayhello", params); // <--- exception

Hi push,

I solved.

Change the system.out to something like this:

org.jboss.logging.Logger.getLogger("wwww").error("Ciao");

System.out involves a call to a private nested class method which can't be run inside a script... (I suppose)
